Because there is almost no difference between composition of basalt fiber material itself and aggregate, it is not hydrophilic stone, just changes in shape, basalt fiber is not only compatible with asphalt, but also can make up the lack of connection due to the shape of aggregate itself.
So the fiber in asphalt concrete material withstands greater force under the synthetic action of external load and freeze-thaw, plays its own performance.
