Abstract:
Aimed at asphalt concrete pavement cracks, the anchor steels were placed on the base course and the surface course of asphalt pavement structure lengthwise to give the prestress to the structure to prevent the cracks. A research is made contrastively on the test pieces with anchor steel and without anchor steel through indoor experiment to analyze the applicational effects on different types of anchor steel. The result shows that the tensile strength, the bending tensile strength and the fatigue performance of the test pieces with anchor steel are increased to 60.74%、46.40% and 134.02% separately. The tensile strength of the test pieces with the anchor steel of diameter of 1.3 mm welded angel bar is the maximum, and the bending tensile strength and the fatigue performance of the test pieces with the anchor steel of diameter of 1.1 mm added the small pommel is the maximum. 3 tabs, 10 figs, 11 refs.
