Intensifying the Road Performance of Asphalt Concrete by Matching the Size Distribution of Short-Thin Straw Pieces and Aggregate Framework
AbstractIn order to reduce costs and prevent environmental pollution in the fabrication process of straws fibrosis, a simple and efficient method of straw reinforcing asphalt concrete is proposed, which means to add short-thin straw pieces (STSP) into asphalt mixture directly by matching the size distribution of STSP and the aggregate spacing of asphalt mixtures. The road performances were testified in terms of the properties of bending, rutting and Marshall stability of the prepared straw asphalt concrete (SAC) samples. The results show that the flexural strength of asphalt mixture increased by 6%, the dynamic stability increased by 54% (reached 1,592 times) while the rut depth decreased by 24%. In addition, based on the analysis of the adhesion, shear lag and bridging effect of STSP, etc., a mechanism of enhancement is illustrated.
