Skid Resistance Performance of Asphalt Mixtures Containing Recycled Pavement Materials under Simulated Weather Conditions

One of the challenges using recycled materials in road structures is to maintain safe and durable pavements. A multitude research has been conducted over years on various materials, with a focus structural performance Another crucial, but almost overlooked, aspect pavement’s ability provide adequate skid resistance for users under different climatic conditions. With this mind, present study aimed investigate asphalt mixtures containing two types laboratory-simulated weather Conventional hot-mix (HMA) either reclaimed pavement (RAP) aggregate replacement or crumb rubber (CR) as bitumen additive were prepared tested at temperatures surface conditions (i.e., dry/wet) following wetting protocol. Skid was measured British Pendulum Tester (BPT). The results showed that performed similarly conventional ones terms when temperature varied variable simulated too. In some cases, they even better than mixtures. Overall, promising potential demonstrated towards use investigated courses.
