摘要
In order to improve the anti-erosion performance of cement-stabilized macadam base material, polypropylene fiber reinforced cement-stabilized macadam base material was made to investigate the effects of fiber content, fiber length, cement content, curing age and eroding time on its anti-erosion property by MTS (material test system). The anti-erosion improvement mechanism of polypropylene fiber was analyzed from material composition, strength theory and fracture and damage theory .The test results show that the eroding rate in 20 min of 14 d polypropylene fiber reinforced cement-stabilized macadam base material at 10 Hz alternating load can be used to evaluate its anti-erosion performance. Reasonable proportion design of polypropylene fiber reinforced cement-stabilized macadam base material reduced the eroding amount more than 30% compared with ordinary cement-stabilized macadam base material.
