      <title>Modelling and optimization of viscoelastic flow behaviour of thermoplastic resin modified asphalt binder in dynamic shear domain</title>
      <link>https://trid.trb.org/View/2601027</link>
      <description><![CDATA[In response to the increasing demand for high-temperature durability in asphalt pavements, the modification of asphalt binders using thermoplastic resin (TPR) additives has gained attention due to their aromatic structure, chemical compatibility, and ability to improve rutting resistance. This study investigates the viscoelastic flow behavior and performance optimization of TPR-modified asphalt (TPRMA) binders through a comprehensive experimental and numerical modeling framework. A petroleum-derived thermoplastic resin was incorporated into a 70/100 penetration grade asphalt binder at different ratios (1 %, 3 %, 5 %, 7 %). Rheological characterization was performed using Dynamic Shear Rheometer (DSR) tests under a wide range of temperatures and frequencies. Master curves of complex viscosity were constructed using time–temperature superposition and fitted with Cross and Carreau-Yasuda models. Both models showed excellent agreement with experimental data (R2>0.99), with 5 % TPR yielding the highest zero-shear viscosity and lowest critical shear rate. In the second phase of the study, Response Surface Methodology (RSM) was employed to optimize the G*/sinδ parameter, a critical indicator of rutting resistance. RSM model was developed (R2=0.9922; p < 0.0001), and numerical optimization identified 5.702 % TPR at 64 °C as the optimum formulation, producing a predicted G*/sinδ value of 5453.91 Pa. Post-analysis confirmed the statistical reliability of the prediction, with tight confidence and tolerance intervals enclosing the target response. Regression coefficient analysis further emphasized the dominant effects of temperature, TPR content, and their interactions. Overall, the findings highlight that moderate dosages of thermoplastic resin, particularly around 5 %, significantly enhance the high-temperature performance of asphalt binders.]]></description>

      <title>Performance of natural asphalt as a paving material: A laboratory and field evaluation</title>
      <link>https://trid.trb.org/View/2447804</link>
      <description><![CDATA[The ever-growing need to build roads to meet the necessary transportation demands is challenging, especially for developing countries. Low-volume roads (LVRs) are usually the backbone of catalyzing economic growth in these countries. With impediments surrounding Petroleum bitumen (price fluctuations) and environmental concerns, scientists are putting their effort into finding an alternative. The presented research is an attempt to check if Natural asphalt can be used as a full or partial replacement of the Petroleum bitumen. To the best of the authors' knowledge, only limited studies have focused on characterizing and understanding the engineering properties of Natural asphalt. The available techniques do not provide reliable information to the road authorities and hence they are discouraged from using it in practice. Particularly for countries, where the Natural asphalt source is available, the overall dependence on importing the Bitumen could be substantially reduced. Empirical and experience-based design criteria may not be sufficient as the standards were never developed for such materials, hence, a scientific approach is required before bringing it into practice. In this research, Natural asphalt sourced from different locations in Nigeria was assessed. Before performing the mixture level tests using Marshall and Cantabro design methods, the rheological and fatigue properties of the extracted Natural bitumen were examined in the laboratory. In the design of the experiment, various percentages of Natural asphalt were added between 0 % and 20 % by total mix weight; implying that the remaining required fraction of binder was fulfilled by the addition of petroleum bitumen. By using a ranking system (supported by statistics), an optimal design of mixture was obtained which was used in the field (exposed to normal traffic) at 30 different sections. Overall, results showed a good correlation between laboratory and field performance as compared to the petroleum-based mixture which was used as a reference mixture]]></description>

      <title>A distributionally robust optimization model for inventory-transportation integrated optimization problem of petroleum products under uncertainty</title>
      <link>https://trid.trb.org/View/2404426</link>
      <description><![CDATA[In the downstream supply chain of petroleum products, the logistics planning optimization is a crucial issue that not only involves the inventory management of oil depots to stabilize market supply, but also needs to take transportation into account and develop a reasonable resource allocation plan associated with replenishment costs. However, the fluctuation of market sales makes oil product outbound volumes full of uncertainty, which also increases the challenge and difficulty of planning optimization. Therefore, this paper investigates the inventory-transportation integrated optimization problem of petroleum products, proposes a novel distributionally robust optimization (DRO) modeling method aiming at a solution scheme addressing the uncertainty in real business. Firstly, considering the uncertainty of random variable distribution, an ambiguity set is confirmed based on the maximum mean discrepancy (MMD) metric. Subsequently, a MMD-DRO model is combined and transformed into an equivalent and solvable mixed-integer linear programming model. Futhermore, with regard to the deficiency of solvers in handling large-scale regional problems, a logic-based Benders decomposition (LBBD) algorithm is designed and enhanced by heuristic strategies. Finally, with the cases from PetroChina, the efficacy and applicability of the proposed approach are validated, and demonstrated the superior performance of the improved LBBD algorithm.]]></description>

      <title>Evaluation of Rheological and Failure-Based Recycling Agent Optimization Methods</title>
      <link>https://trid.trb.org/View/2353886</link>
      <description><![CDATA[This study examined rheological and failure-based approaches for the optimization of two bio-based and two petroleum-based recycling agents (RAs). The results showed that optimizing the RAs based on the performance grade (PG) approach did not fully achieve the rheological and failure characteristics of the target asphalt binder. This was observed for both a bio-based and a petroleum-based RA. The asphalt binder quality test (ABQT) and Glover–Rowe (G-R) approaches showed potential as surrogate methods for estimating the optimum dosage of RAs, whereas the double-edge notched tension (DENT) approach provided a more cost-effective dosage. This needs to be further evaluated through future mixture-level testing and in situ experiments. The selected dosage of each RA, based on the high-end PG, was then applied to a mixture containing 40% reclaimed asphalt pavement (RAP) to achieve the target performance, which was a mixture with 20% RAP. The mixture characteristics were evaluated using the Hamburg wheel tracking test (HWTT) for rutting and moisture damage characterization and the indirect tensile asphalt cracking test (IDEAL-CT) for cracking characterization. The results showed that the addition of RAs improved the cracking resistance of the 40% RAP mixtures without significantly affecting their rutting resistance. The RAs used in this study did not negatively affect the moisture damage resistance of the mixtures. After long-term aging conditions, all mixtures exhibited diminished cracking resistance. The comparison between the aging protocols highlights varied performance among these mixtures, underscoring the necessity for further research in the selection of appropriate aging protocols. Overall, the results revealed that bio-oil-based RAs compare favorably with petroleum-based ones.]]></description>

      <title>Tabu-Based Adaptive Large Neighborhood Search for Multi-Depot Petrol Station Replenishment With Open Inter-Depot Routes</title>
      <link>https://trid.trb.org/View/2108325</link>
      <description><![CDATA[The petrol station replenishment problem (PSRP) refers to the process of transporting petroleum products from oil depots to petrol stations via tank trucks. It mainly consists of two parts: allocating petroleum products to tank trucks and planning the travel route of each truck. In this study, the authors examine a new variant of PSRP by considering a multi-depot vehicle routing problem with open inter-depot routes (MDVRPOI). Each depot can act as an intermediate replenishment facility, and each truck can be reloaded at any depot any number of times within the working period. Moreover, trucks can end their routes at any depot instead of making a long empty drive to the start depot. The trucks are heterogeneous with multiple load-specific compartments. They formulate the problem as a mixed-integer linear programming (MILP) model. Given the problem’s complexity, a tabu-based adaptive large neighborhood search (T-ALNS) algorithm is proposed, which integrates the tabu search approach into ALNS to solve the problem effectively. The T-ALNS executes multiple problem-tailored destroy/repair operators on the station, trip, and route levels. A local search procedure with problem-specific operators and an adaptive strategy is further embedded into T-ALNS. They use the real data of an oil company in China to evaluate their algorithm. Computational results show that theor T-ALNS significantly outperforms the CPLEX solver and other algorithms in terms of solution quality and computation time. Further, it realizes an average reduction in transportation cost of about 45% compared to the company’s actual strategy.]]></description>

      <title>Modification mechanism of C9 petroleum resin and its influence on SBS modified asphalt</title>
      <link>https://trid.trb.org/View/1879137</link>
      <description><![CDATA[In this paper, C9 petroleum resin was used as the raw material, and the microstructure of C9/SBS modified asphalt at a different time under different C9 petroleum resin content was studied by fluorescence microscope. The mechanical properties were studied by using the whole section fracture energy, the pavement performance of C9/SBS modified asphalt was tested and analyzed. The results show that C9 petroleum resin is conducive to SBS particles being sheared into smaller particles under the same preparation process. The larger the content of C9 petroleum resin, the smaller the final size of SBS particles, and the smallest SBS particle size can be reduced by about half. When the content of C9 petroleum resin is more than 9%, the decreasing trend is no longer obvious. This phenomenon mainly occurs in the final stage of shearing. C9 petroleum resin can affect the swelling behaviour of SBS in asphalt and its final microstructure by reducing the particle size of SBS. The larger the content of C9 petroleum resin, the larger the area occupied by SBS after swelling, and the longer the skeleton length of SBS, the easier the crosslinking occurs and the denser the crosslinking network structure is formed. The addition of C9 petroleum resin can effectively improve the fracture energy density of SBS modified asphalt, and its mechanism is closely related to the effect of C9 petroleum resin on the shear particle size and final swelling degree of SBS particles. C9 petroleum resin can effectively hinder the floating and aggregation of SBS modifier in asphalt during high-temperature storage, thus improving the storage stability of SBS modified asphalt. The incorporation of C9 petroleum resin can significantly increase the viscosity of SBS modified asphalt, improve the low-temperature performance of SBS modified asphalt, and improve the anti-ageing performance of SBS modified asphalt. The results provide a new way to improve the performances of SBS modified asphalt.]]></description>

      <title>Effect of Soy-Based Asphalt Rejuvenators on Asphalt Binders of Different Performance Grades</title>
      <link>https://trid.trb.org/View/1756901</link>
      <description><![CDATA[The objective of this study was to evaluate the effect of three soy-based biorejuvenators and one conventional petroleum-based oil on aged asphalt binders. Two neat asphalt binders (PG 64-22 and PG 70-16) were aged in a rolling thin-film oven (RTFO) and in a pressurized aging vessel (PAV). Different proportions of rejuvenating agents (RA) were added to the aged binders, and the rheological properties were measured. Rejuvenation effectiveness was also assessed through Fourier Transform Infrared spectra and a reduction of the chemical aging indices. The overall results indicated that the soy-based bio-oils were able to restore the rheological and chemical properties of aged asphalt. The optimum content of the bio-oils that resulted was relatively lower than that obtained for the petroleum-based oil, which can be explained by the lower viscosity of these biomaterials. The Fourier transform infrared analysis indicated that both the petroleum-based oil and the bio-oils were able to rejuvenate the aged binders by restoring the chemical aging indices, at least partially, to the condition of the virgin binder, with the bio-oils performing better than the petroleum-based rejuvenator.]]></description>

      <title>Evaluation of the chemical composition and rheological properties of bio-asphalt from different biomass sources</title>
      <link>https://trid.trb.org/View/1741282</link>
      <description><![CDATA[This paper presents the findings of a study conducted to evaluate the potential effect of bio-asphalt from corn and wood waste on the rheological properties of styrene–butadiene–styrene/rubber composite-polymer modified asphalt. Results showed that bio-asphalt from corn contained significantly high amount of oxygen (62%), whereas petroleum-based asphalt only contained trace amounts of oxygen (0.91%). The average molecular weight, total rings per average molecule, naphthenic carbon rate, and aromaticity of bio-asphalt from corn were smaller than that of petroleum-based asphalt. Meanwhile the characteristics of bio-asphalt from wood waste were similar to that of petroleum-based asphalt, yet the molecular size and polarity of bio-asphalt were slightly lower. For workability, the addition of bio-asphalt decreases the viscosities of composite-polymer modified asphalt. Samples with bio-asphalt from wood waste presented higher viscosity than that with bio-asphalt from corn at the same added amount. A suitable amount (15%) of bio-asphalt showed the best anti-rutting properties under all conditions owing to bio-asphalt can function as light oil to swell polymer or act as a lubricant to limit the intermolecular interactions. Moreover, the addition of bio-asphalt from corn increased the anti-cracking property, whereas the increasing degree of adding bio-asphalt from wood waste were not obvious. The m-values of samples with bio-asphalt from wood waste were also smaller than that of samples added with bio-asphalt from corn. The stiffness of modified asphalt with bio-asphalt from wood waste decreased with an added amount of less than 15% and increased when the bio-asphalt amount exceeded 15%. Samples with bio-asphalt from wood waste also provided better durability and storage stability than that with bio-asphalt from corn. Therefore, bio-asphalt from wood waste was more suitable to represent petroleum-based asphalt partly than bio-asphalt from corn.]]></description>

      <title>Characterizing petroleum hydrocarbons deposited on road surfaces in urban environments</title>
      <link>https://trid.trb.org/View/1568063</link>
      <description><![CDATA[Petroleum hydrocarbons are a toxic pollutant group, primarily including volatile organic compounds (VOC), semi-volatile organic compounds (SVOC) and non-volatile organic compounds (NVOC). These pollutants can be accumulated on urban roads during dry periods and then washed-off by stormwater runoff in rainy days. Unlike heavy metals and polycyclic aromatic hydrocarbons, petroleum hydrocarbons have not received an equal attention in the field of stormwater pollutant processes. This paper investigated characteristics of VOC, SVOC and NVOC pollutant loads deposited on urban roads and their influential factors using a forward stepwise regression and PROMETHEE-GAIA analysis techniques. The results indicate that the loads deposited on urban roads were NVOC > SVOC > VOC. It is also noted that the degrees of factors in influencing petroleum hydrocarbons deposited on urban roads did not equal and their order was total solids > land use type > vehicular traffic > roughness of road surfaces. The research results also showed that petroleum hydrocarbons on urban road surfaces tend to be source limiting rather than transport limiting. These outcomes can contribute to petroleum hydrocarbons polluted stormwater management, such as treatment system design and stormwater modelling approach improvement.]]></description>

      <title>Development of Hot Mixture Asphalt for Oil Resistance and Rutting Resistance</title>
      <link>https://trid.trb.org/View/1573794</link>
      <description><![CDATA[Transportation vehicles run over asphalt pavement and cause rutting. Polymer modified asphalt is used as a technical countermeasure to rutting, and offers expectations for some level of improvement. The impact of global warming, however, has led to an increased number of days during the summer in Tokyo when the temperature exceeds 35˚C and days when the pavement road surface temperature exceeds 60˚C. Consequently, demands to counteract rutting are mounting. Since asphalt used in asphalt pavement is a product derived from petroleum, its resistance to mineral oils is low. Erosion caused by these has been noted to lead to impairments such as potholes. Semi flexible pavement and epoxy asphalt concrete with superior rutting resistance and oil resistance are used for pavement in response to the above. They present challenges, however: Special techniques are required during manufacture of the mixture or during pavement construction, and recycling is difficult. For the purpose of improving pavement durability, therefore, the authors have developed the high stability asphalt mixture that can be handled in the same manner as conventional asphalt mixture. This paper describes the laboratory assessment of durability for the developed mixture, and various application cases that used this mixture.]]></description>
