Abstract
This paper describes a specific laboratory test method for measuring asphalt mixture shear resistance, which is denominated as co-axle shear strength test. The test rationality and reliability are discussed and emphasized. According to finite element analysis results and co-axle shear test specimen failure plane, the position of max shear stress is determined then. The max shear stress in specimen under 1 kN unit vertical loading is defined as shear strength coefficient, which is hardly influenced by mixture modules in normal temperature range from 15 ℃ to 60℃. Then shear strength coefficients are given as a constant and equals to 0. HO MPa · kN-1. The regression analysis of laboratory test results shows good relationship between co-axle shear strength and permanent deformation or DS.关键词
