	1	Investigation on mechanical properties and water stability of porous polyurethane concrete显示文摘Porous polyurethane concrete(PPUC)is a novel material for permeable pavements and is considered as an alternative to porous asphalt or porous cement concrete.However,studies of the mechanical properties of PPUC are still insufficient.In this study,the comprehensive mechanical properties and water stability of PPUC with different gradations and polyurethane dosages were investigated,and its water damage mechanism was preliminarily explored.The results show that the flexural strength and Marshall stability of PPUC can more easily reach the index in the standards of porous cement concrete or porous asphalt,while the compressive strength and abrasion resistance are the weak points of its mechanical properties and need to be further optimized.The mechanical properties and water stability of PPUC were effectively improved by increasing the polyurethane dosage and using continuously graded aggregates.PPUC is more susceptible to water damage because water reacts with the residual isocyanate groups within the polyurethane film to generate carbon dioxide gas,which reduces the cohesion and adhesion performance of polyurethane film.This study provides a comprehensive understanding of the mechanical properties of PPUC and an initial insight into the mechanism of water damage.
