New technology of reinforcement materials in asphalt overlays can offer a potentially cost effective solution for treating cracked pavements. To date, however, there is no design process allowing the use of available reinforcement products in road applications in Australia; whereas overseas design procedures are not readily available. A new 3D finite element (FE) analysis procedure was considered where reinforced asphalt layer is modelled as a thin 3D compound non-homogeneous layer which is then converted into a 3D orthotropic membrane. This procedure was used to analyse performance of three reinforcing products for road applications in Australia and results indicated that it is possible to predict and compare "retard reflection cracking" performance of various reinforced products.
