Abstract:
In order to obtain the interfacial bond factor of semi-contacted bi-layer asphalt mixture beam, the theoretical analysis method was applied to deduce the computational formula for semi-contacted bi-layer asphalt mixture beam. The reasonable bending test was designed to measure the relative parameters in theoretical formula, and on the base of measured results, the interfacial bond factor of semi-contacted bi-layer beam was calculated. At last the interfacial bond factors、 of the semi-contacted bi-layer asphalt mixture beams with bonding oil contents of 1 kg/m2, 2 kg/m2 were respectively calculated out to be 0.348 and 0.406. The research indicates that: it is feasible to calculate the interfacial bond factor of semi-contacted bi-layer asphalt mixture beam by the method of theoretical analysis combining with test simulation. The interfacial bond factor calculated can be used as the index for evaluating the interface treatment of bi-layer beam and the basis for selecting the optimal bonding oil content between layers. 2 tabs, 3 figs, 8 refs.
