RESEAECH ON THE APPLICATION OF POLYPROPYLENE ANTI-CRACK BASE CLOTH IN EXTEND ROAD
In order to study the anti-reflective crack effect of polypropylene filament anti-crack base cloth on high-way pavement,the anti-crack effect of asphalt concrete pavement is studied and evaluated by vehicle load test and core shear strength tests.The experimental results show that the sample with polypropylene filament anti-cracking base cloth experiences 2.65 times more loading times than that without polypropylene filament anti-cracking base cloth,and the core shear strength with polypropylene filament anti-cracking base cloth is more than 46%higher than that without polypropylene filament anti-cracking base cloth.At the joint of new semi-rigid base asphalt con-crete pavement and old pavement,adding polypropylene filament anti-crack base cloth delays the generation of re-flective cracks in pavement and improve the safety and reliability of road engineering.
