| Abstract: | Factors affecting the mechanic performances of composite base were studied in this paper.Some appropriate indexes in long-life pavement design were analyzed,and the sensitivity to the parameters affected by thickness and modulus was studied.An orthogonal experiment was designed to calculate the mechanic performances of the variation parameter combinations with BISAR software.Furthermore,the parameters were optimized.Under standard loads,the strain of the asphalt treated base(ATB) in the optimized structure ... |
