Retracted: Experimental Study on Fiber Content in Asphalt Mixture

The optimum dosage of fiber in asphalt mixture is affected by the fiber adsorption capacity, the gradation of mineral aggregate and the dispersion of fiber. The skeleton dense asphalt mixture as the main research object, such as SMA, according to the mineral Fiber content of 0%, 0.3%, 0.5%, 0.7% and 0.9%, selection of basalt fiber, using rutting test and bending test, high temperature stability, comparing the different conditions of asphalt mixture low temperature crack resistance, determine the best content of mineral fiber, in order to improve the pavement performance of asphalt mixture.
