Highlights Polyurethane rubber particle mixture (PRPM) is developed as a sustainable material. Comprehensive performance of polyurethane rubber particle mixture is evaluated. Mixture F5 is the most suitable PRPM for future application.
Abstract Poroelastic road surface is a type of pavement surface which makes full use of waste rubber and at the same time effectively reduces traffic noise. However, the comprehensive performance of polyurethane rubber particle mixture (PRPM) prepared with different kinds of rubber particles and polyurethane is rarely studied. This study aims to evaluate the comprehensive performance of PRPMs, such as the high-temperature performance, anti-aging performance, skid resistance performance, etc. Rubber particles and four different kinds of polyurethane were adopted to prepare polyurethane rubber particle mixtures. A dog bone shape mold for forming specimens was self-designed, and a slab specimen forming device was created to form slab specimens. Different test methods were conducted to evaluate the comprehensive performance of the mixtures. The results showed that four types of polyurethane rubber particle mixtures exhibited high rutting resistance and high temperature performance. Mixture F5 had the best anti-aging performance and noise reduction performance. The skid-resistance of the polyurethane rubber particle mixture was slightly lower than that of conventional asphalt mixture, but it still met the road specification requirements. The polyurethane rubber particle mixture had more interconnected pores, which was found to have greater drainage function and was expected to reduce noise. Polyurethane rubber particle mixture F5 had superior comprehensive performance, except for slightly lower skid resistance, and it was determined to be the most suitable polyurethane rubber particle mixture type for future application.
