Abstract:
In order to alleviate the brittleness development and pavement damage of polymer pervious concrete pavement after hardening, based on previous experience and conclusions, the road performance of polypropylene fiber modified polymer pervious concrete pavement was studied. The road section model was made by using solvent-free polyurethane as adhesive and polypropylene fiber pervious concrete as road surface layer. A series of tests on chloride ion permeability, bearing capacity, impact resistance and runoff reduction of pavement were carried out, and the results were compared with those of ordinary pervious concrete. The results show that the permeability coefficient of ordinary concrete and polymer pervious concrete is 81% and 92% of the initial value respectively. The ordinary pervious concrete is easier to block than polymer pervious concrete, mainly because polymer emulsion improves the working performance of new pervious concrete and improves the compactness of concrete. There are a lot of active substances in latex, which increase the adhesion of latex to aggregate and hydration products during the hydration and hardening of concrete. The surface bearing capacity of polypropylene fiber modified polymer pervious concrete is 52% higher than that of polymer pervious concrete. With the increase of polypropylene fiber content, the impact resistance is enhanced. When adding polypropylene fiber is 1.5%, the impact resistance is increased by 245.9%. The rainfall runoff coefficient of polypropylene fiber modified polymer pervious concrete pavement is 0.11-0.29, which has better runoff reduction effect than ordinary pervious concrete pavement.
