Study on the influence of basalt fiber content on the road performance of rollable pavement.

Add SBS modified asphalt with 10% rock asphalt and 15% rubber powder as base material, and mix 0, 0.1%, 0.3%, 0.5% basalt fiber and appropriate basalt grade gravel to make asphalt flexible pavement mixture. The effect of basalt fiber content on road performance of pavement asphalt mixture was studied. The results show that with the increase of basalt fiber content by 0, 0.1%, 0.3%, 0.5%, the rutting test dynamic stability, low temperature bending failure strain and water immersion Marshall residual stability of pavement asphalt mixture increase first and then decrease, normal temperature bending failure strain is gradually increased. Adding appropriate amount of basalt fiber can effectively improve the road performance of the prefabricated curable asphalt mixture. [ABSTRACT FROM AUTHOR]
