Road Performance of Polyurethane Rubber Particle Mixture

Poroelastic Road Surface (PERS) 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 mixtures based on the different kinds of rubber particles and polyurethane were not fully investigated. This study aims to investigate the comprehensive road performance of polyurethane rubber particle mixtures, such as the high-temperature performance, anti-aging performance, skid resistance performance. Rubber particles and four different kinds of polyurethane were adopted to make polyurethane rubber particle mixtures. A dog bone shape mold for forming specimens was designed and flat plat specimen forming device was developed to form the flat plat specimen. Tests were conducted to evaluate the comprehensive performance mixtures. The results shows that all types of polyurethane rubber particle mixtures exhibit excellent rutting resistance, and the polyurethane rubber particle mixture has excellent high temperature stability. Mixture FS9005A has the best anti-aging performance. The skid-resistance of polyurethane mixture is slightly worse than that of traditional asphalt mixture, but it basically meets the road specification requirements. The polyurethane rubber particle mixture has good interconnected pores and excellent drainage effect, which can be expected to have good drainage and noise reduction functions. Polyurethane rubber particle mixture FS9005A is excellent in road performance analysis, except for slightly poor skid resistance, other performances are all satisfied, and it is the most suitable polyurethane rubber particle mixture type.
