Assessment of reinforced asphalt products for road applications using finite element modelling

Several reinforced asphalt products are being investigated for use in road applications, particularly for rehabilitation of existing cracked reinforced-concrete pavements required for heavy-duty pavements. The products are assessed based on their structural capacity for the specific designs, especially with regard to joints or cracks in the underlying layers using new 3D nonlinear finite element (FE) analysis procedures. This allows comparison of relative performance of various reinforced products and, hence, selection of the most effective solution for the designs concerned. Other factors influencing their use such as availability, costs and long-term environmental sustainability are also considered to examine the suitability of reinforced asphalt products for long-term cost-effective solutions over the traditional asphalt materials. This will help the issues of sustainability in material selection for pavement works. (a) For the covering record of the conference, please refer to ITRD no. E218387.
