Abstract:
According to the Sayers M W theory and measurement results of asphalt pavement unevenness, the pavement surface was simulated by using sine curve. Based on the coupling of vehicle dynamic loading and surface unevenness, vehicles moving load caused by road surface roughness was analyzed and calculated through complex mode theory and Matlab, VC++ program. Considering the factors of dynamic road and environment, and combining the test results of highway surface roughness,the pavement evenness deterioration law was studied by amendment shell permanent deformation theory. Based on the above, a new forecasting method was proposed to predict the remaining life of asphalt concrete pavement, and the method was proved to be reasonable and reliable, which can provide reference for scientific decision-making of pavement management. 1 tab, 3 figs, 13 refs.
