      <title>Nebraska Department of Roads Transportation Asset Management Plan (TAMP)</title>
      <link>https://trid.trb.org/View/1697697</link>
      <description><![CDATA[The goal of this project was to develop a document that describes the overarching Transportation Asset Management Plan for Nebraska. Note that this document is a summary document and that most of the technical details can be found in the supporting documents. A partial list is shown in the References section. Appendix A lists the outline of the proposed summary document. Note that this project summarizes what is currently being done in Nebraska as related to asset management activities defined by the Moving Ahead for Progress in the 21st Century Act (MAP-21). There are no recommendations or studies on current asset management practice. This document allows Nebraska Department of Roads  (NDOR) to meet the requirements of MAP-21 related to Transportation Management Plan documentation. This document was forwarded to the Federal Highway Administration (FHWA) for approval.

      <title>Freeway Safety Evaluation: A Quantitative Approach Using Highway Safety Manual to Informed Decisions</title>
      <link>https://trid.trb.org/View/1497408</link>
      <description><![CDATA[Performance-based design in the form of operation and safety in the freeway system plays a significant role in alternative evaluation process. Moreover, performance-based design consistent with Highway Safety Manual is getting more accepted and adopted by the highway agency since it sets specific goals in meeting safety targets that lead to meet performance criteria. Nebraska Department of Roads (NDOR) sets targets by using the systematic safety assessment on design modifications. The application of Highway Safety Manual (HSM) in the safety assessment of freeway alternatives focusing on Metropolitan Travel Improvement Study (MTIS) provides a new direction for making informed decisions at the agency level. With that in mind, this study was conducted with the objectives to perform: (1) safety performance evaluation of alternatives in the MTIS by applying Enhanced Interchange and Freeway Safety Analysis Tool (ISATe); (2) safety performance evaluation of design exceptions; and (3) qualitative safety performance evaluation of sub-options as part of sensitivity analysis for design year 2040. This paper focuses on a performance-based approach to compare safety performance of alternatives and provides information to assist safety professionals, designers, planners, and policy makers at state and local levels in making informed decisions. Finally, this study highlights some of the challenges of using predictive tool recommend by HSM in real applications.]]></description>

      <title>Effectiveness Study of UNL’s Crack Routing Device (CRD) –
Phase II</title>
      <link>https://trid.trb.org/View/1464019</link>
      <description><![CDATA[This project evaluated the crack routing device (CRD) for effectiveness in improving current crack-cutting practices and for possible adoption as a standard in the Nebraska Department of Roads (NDOR). To enact these evaluations of CRD, the research team collaborated with NDOR to conduct surveys and field tests. Given the positive results obtained from this project, improved road-maintenance practices are anticipated when CRD is used, and this research therefore recommends the adoption of CRD in crack-routing work.]]></description>

      <title>Mitigating Pavement Edge Drop off</title>
      <link>https://trid.trb.org/View/1378629</link>
      <description><![CDATA[The objective of this research was to investigate and document practices currently being used by the Nebraska Department of Roads (NDOR) districts and other State departments of transportation (DOTs) to mitigate pavement edge drop off. The NDOR has developed (or borrowed) and is currently incorporating into its standard practices several procedures that significantly decrease the incidence and magnitude of pavement edge drop off. As these practices become more fully integrated into highway reconstruction projects, pavement edge drop off is expected to decrease dramatically. Localized areas of pavement edge drop off along paved lanes with bare or vegetated shoulders were noted as posing particular problems for NDOR maintenance personnel. Several commercial systems for artificially reinforcing soil beneath vegetated or aggregate shoulders were investigated. Suggestions for follow-on research and field studies involving various mitigation procedures are included in the recommendations.]]></description>

      <title>Avian Protection Plan for the Nebraska Department of Roads</title>
      <link>https://trid.trb.org/View/1346339</link>
      <description><![CDATA[Compliance with the Migratory Bird Treaty Act (MBTA) has presented challenges for the Nebraska Department of Roads (NDOR) and its contractors. NDOR has worked to reduce avian mortality through implementing changes in project scheduling, increasing migratory bird surveys, and introducing changes in project construction timelines to avoid avian conflicts. The attractiveness of bridges/culverts and right of way (ROW) habitat for migratory bird nesting, coupled with the overlap of the primary nesting period and construction season are the basis of the conflicts between avian conservation and construction of highway projects. The implications of the conflicts range from construction delays and shutdowns to the potential for violating the federal law (MBTA), resulting in costly claims and fines. NDOR was one of the first state transportation agencies to employ a Liaison with USDA-APHIS-Wildlife Services (WS). NDOR sought the expertise that the liaison provided concerning migratory birds. Additionally, the Liaison was able to use the WS depredation permit to take migratory birds if a conflict arose during construction. In 2006 though, an informal opinion from the United States Fish and Wildlife Service (FWS) solicitor’s office ended the use of the WS depredation permit (on NDOR projects), prompting NDOR to explore other avenues to comply with the MBTA, while minimizing effects on NDOR’s construction program. Avian Protection Plans (APP) are being developed by public and private entities nationwide, and NDOR recognized this as a way to formalize the department's MBTA procedures and to provide a resource for NDOR employees and contractors. NDOR’s APP is one of the first among transportation agencies. By implementing the APP, NDOR will attain its goals of (1) protecting and conserving avian populations and (2) reducing conflicts between construction of NDOR projects and the laws governing migratory bird protection. NDOR’s environmental stewardship will be enhanced, detrimental effects on migratory birds will be reduced, and regulatory compliance will be achieved with the implementation of this new plan.]]></description>

      <title>Development and Implementation of a Programmatic Agreement for Endangered Species Act Consultation in Nebraska</title>
      <link>https://trid.trb.org/View/1347268</link>
      <description><![CDATA[In December of 2008, the Nebraska Department of Roads (NDOR), the Federal Highway Administration-Nebraska Division (FHWA), the U.S. Fish and Wildlife Service-Nebraska Ecological Services Field Office (USFWS), and the Nebraska Game and Parks Commission (NGPC) all began working on a Programmatic Agreement (PA) for Endangered Species Act (ESA) and Nebraska Non-game and Endangered Species Conservation Act (NESCA) consultations. What resulted was a standardized, streamlined, approach for conducting endangered and threatened species consultations in Nebraska. Standardized effect determinations were agreed to, based on construction activity type, onsite species records/habitat conditions, and also included the development of standardized conservation conditions (measures) for all state and federally-listed species that are also implemented at the project level. This program consultation allows all agencies to meet their individual agency missions efficiently and consistently while decreasing staff workloads and enhancing species conservation on a program level.]]></description>

      <title>Nebraska's "The Matrix Reloaded!": Joint Regulatory Compliance and Agency Collaboration for Streamlined Transportation Project Delivery and Effective Environmental Resource Protection</title>
      <link>https://trid.trb.org/View/1345729</link>
      <description><![CDATA[After finalizing the Nebraska “Matrix” programmatic process in 2012, the “Matrix” would next undergo a new revolution, a “Matrix Reloaded” effort. Part of the “Matrix Reloaded” effort included a joint agency review to evaluate the effectiveness of the tools and implementation of the previous “Matrix” process. This was done through a random sample assessment of projects over a seven month time frame. These projects had been assessed under the current Programmatic Agreement (PA) and approved by Nebraska Department of Roads (NDOR) with no resource agency review. Based on this joint review, it was determined that the process was working as expected, and some additional tweaks were made to further improve efficiency and effectiveness. In addition to the “Matrix” process successfully being implemented, the agency team identified that procedures were still not in place for demonstrating compliance with other regulations such as the Migratory Bird Treaty Act (MBTA), the Bald and Golden Eagle Protection Act (BGEPA), Fish and Wildlife Coordination Act (FWCA) or the Section 404 of the Clean Water Act. Another active “Matrix Reloaded” effort now includes the development and action plan for completing Appendices that would address other biological considerations such as invasive species, contractor borrow, wetlands, migratory birds, wildlife connectivity, etc. These jointly developed compliance procedures will be amended to the existing agreement (PA) upon their completion. This work is a good example of how transportation and the resource agencies can work cooperatively in a collaborative manner to achieve conservation of natural resources.]]></description>

      <title>Research Pays Off: Second-Generation, Full-Depth, Precast Concrete Deck System: Nebraska Department of Roads Applies NUDECK to Improve Constructability and Cost-Effectiveness</title>
      <link>https://trid.trb.org/View/1344100</link>
      <description><![CDATA[There are a number of advantages to using full-depth, precast concrete deck systems instead of cast-in-place concrete decks in bridge construction. These include improved construction quality, decreased impact on the traveling public, possible weight reduction, and a lower bridge life-cycle cost.  However, some of the operations associated with traditional full-depth, composite precast concrete deck systems can complicate the process of fabrication and erection and increase construction costs and duration. This can make precast concrete systems a less attractive solution. This article describes a research project by the Nebraska Department of Roads (DOR) to develop a precast concrete desk system that addresses some of the problems with traditional systems, with a goal of achieving a deck with a service-life expectancy that matches the bridge’s design life.  The project proposes the application of the second generation of a precast concrete deck system called NUDECK, the first generation of which was used to construct the Skyline Bridge in Omaha, Nebraska. The article describes the demonstration and tests of the system, details its application in the construction of the Kearney East Bypass, and outlines the new system’s benefits.]]></description>

      <title>Development of a Mechanical Rocker Test Procedure for Ice Melting Capacity Evaluation</title>
      <link>https://trid.trb.org/View/1315663</link>
      <description><![CDATA[During Phase 2 of the Nebraska Department of Roads (NDOR) deicing chemicals performance evaluation project (No. SPR-P1(10) P328), a simple and economical test using a martini shaker to evaluate ice melting capacity of liquid deicers showed good potential to become a standardized test. There is a need to support an internal effort at NDOR to further develop the shaker test into a deicing chemicals test protocol. A number of parameters of the testing procedure need to be precisely specified to ensure repeatability and accuracy. The main objective of this research is to transform the shaker test into a gold standard for ice melting capacity evaluation of liquid deicing chemicals. This research focused on the use of a mechanical rocker for shaking instead of shaking by hand which can introduce significant error due to the variability of shaking. In this test, 33 ice cubes of 1.3-mL each and 30-mL of liquid deicing chemical are mixed in a vacuum sealed thermos on a mechanical rocking platform. The rocker is set to a frequency of 90 RPM with a tilt angle of ±10°. The time duration for rocking is set for 15 minutes. A styrofoam dish or cup should be used for measuring the mass of ice. With these test parameters, a standard deviation of 1.15% has been achieved when testing with Apex Meltdown™. This Mechanical Rocker Ice Melting Test procedure will be submitted to selected Departments of Transportation and Clear Roads for parallel testing and feedback. The Mechanical Rocker Ice Melting Test can be used for screening of new deicing products submitted to NDOR by vendors each year. Once validated by other independent organizations, the Mechanical Rocker Ice Melting Test may be proposed to the American Association of State Highway and Transportation Officials (AASHTO) for adoption for ice melting capacity evaluation of liquid deicing chemicals.]]></description>

      <title>Effect of Supplementary Cementitious Materials on the Performance of Concrete Pavement</title>
      <link>https://trid.trb.org/View/1303840</link>
      <description><![CDATA[Supplementary cementitious materials (SCMs) have been used in portland cement concrete pavements (PCCP) to increase their resistance to deterioration mechanisms, such as alkali-silica reaction (ASR), freeze and thaw, and permeability. In addition, SCMs are mostly by-products that can effectively reduce material cost and improve concrete sustainability. This paper presents the results of an experimental investigation carried out to evaluate the effect of Class C fly ash, Class F fly ash, and ground granulated blast furnace slag (GGBFS) on the performance of PCCP. Laboratory testing of multiple mixes with different combinations and percentages of SCMs is presented. This testing includes slump, unit weight, air content, time of setting, compressive strength, flexural strength, alkali-silica reactivity, freeze/thaw, length change, chloride ion penetration, and wet/dry test specified by Nebraska Department of Roads (NDOR). Field applications of four candidate mixes at two separate locations are also presented. Test results from laboratory and field investigations indicated that using a combination of Class C fly ash (15–20%) and Class F fly ash (20–25%), or all three SCMs in the range of 15–20% each, improves concrete durability and overall performance.]]></description>

      <title>Developing a Quality Measure for Evaluating the Contractor Performance in Asphalt Pavement Construction</title>
      <link>https://trid.trb.org/View/1246509</link>
      <description><![CDATA[Most construction agencies have a quality management system to control and manage the quality of their final product. Once the project is over, the tests results are usually kept in archives with no use. Project bidding is a time when the quality information could be very helpful to identify qualified contractors. The proposed model is an effort to use quality tests in evaluating the contractor performance. The composite percent defective is proposed as the quality measure which combines percent defectives of a number of selected quality characteristics. The trend analysis is used to provide a better look at the contractor performance. The significance of the proposed measure is in its ability to reflect the true quality of the contractor work being calculated based on actual tests results.]]></description>

      <title>Implementation of the AASHTO LRFD Code in Geotechnical Design-Piles</title>
      <link>https://trid.trb.org/View/1239496</link>
      <description><![CDATA[The Load and Resistance Factor Design (LRFD) of the American Association of Highway and Transportation Officials ( AASHTO)(2007) includes substantial changes compared to the AASHTO Standard Specifications (2002). Therefore, State Departments of Transportation have to review their current practice and, if needed, develop a new approach that is consistent with the LRFD philosophy. Load and resistance factors in LRFD code were determined in the reliability-based calibration process. However, this calibration was limited to the superstructure. The resistance factors for the piles were mostly based on engineering judgment. Therefore, there is a need for verification of a pile design provisions. The objectives of this study were to review the available pile capacity analysis methods and develop a user-friendly and possibly more accurate formula. In addition, a procedure was developed for comparison of the pile design and the calculation of the resistance factors. The following methods of determining the load carrying capacity of a pile were compared: Static Load Test, Case Pile Wave Analysis Program (CAPWAP), Wave equation, Gate formula, and Nebraska modified Engineering-News (ENR) formula. A formula has been proposed for the calculation of the pile capacity that is in good agreement with the CAPWAP results. The resistance factor has been calculated based on the assumption that the LRFD AASHTO Code and the AASHTO Standard Specifications result in the same design of a pile. The calculations were carried out for a representative number of design situations (pile material, pile type and soil conditions).]]></description>
