Porous Asphalt Pavement Binder Performance and Standards under High Temperature and Heavy Load Conditions

Because of its porous, noise-reduction, and anti-skid qualities, porous asphalt pavement has attracted a lot of interest from the transportation industry recently. However, the porous asphalt pavement is prone to rutting deformation due to high temperature and heavy vehicles. To address this issue, we use high-viscosity binder to improve pavement performance and propose a technical standard for asphalt binder for porous asphalt pavement. The study about the performance of asphalt binder and the impact on the road performance of porous asphalt pavement under high temperature and heavy vehicles is currently being conducted. The research results can provide support for the application and popularization of porous asphalt pavement.
