The experimental research on the influence of cellulose fiber to different types of asphalt mixture

摘要

Based on the Marshall test adding cellulose fiber to the AC-13 I asphalt mixture, the influence of fiber on the content of asphalt is studied, the optimal fiber content of cellulose fiber is obtained; Through adding cellulose fiber to the AC-13 I, OGFC-13 and SMA-13 asphalt mixtures, high-temperature rutting test is carried on, the enhancement capacity of fiber in different types of mixture is studied, the optimum fiber content is obtained from the fiber reinforced capacity, and the dynamic stability computational model of fiber-reinforced asphalt concrete is established ; Through adding cellulose fiber to the SMA-13 asphalt mixture, the Schellenberg Binder Drainage Test is carried on, the composition and mechanism of asphalt Matrix is analyzed, the Cantabro Test, the relationship model between dynamic stability of SMA and the loss of Schellenberg Binder Drainage Test is established ; Through adding cellulose fiber to the OGFC-13 and SMA-13 asphalt mixtures, the water stability test is carried on, and the anti-water damage mechanism of fiber is analyzed; At last, through adding cellulose fiber to the SMA-13 asphalt mixtures, the relationship model between parameters of water stability and the loss of Cantabro Test is established.
