    Research of Porous Asphalt Concrete Application on Highway Sections with The Increased Aquaplaning Danger Level by Oleksandr Rieznik, Shilin Yang, Andrii Bieliatynskyi, Meiyu Shao, Mingyang Ta

    Published 2023-09-01
    “…The construction of the road surface was also improved with the separation of the pavement layers, where porous asphalt mixture was used as the top layer, and the basalt canvas (impregnated) between the used construction levels was used. The mathematical calculation of the road was improved taking into account the physical phenomena occurring between the car and the road surface in the presence of water. …”
