摘要
研究了路面结构层厚度误差对模量反算结果的影响 .结果表明 ,路面结构层厚度误差对模量反算结果具有较大的影响 .各层厚度误差对底基层模量反算结果影响较大 ,而对土基模量反算结果影响甚微 .当各结构层厚度误差控制在± 5 %以内时 ,可以使反算的各结构层模量误差不超过± 1 5 % .
The effect of the thickness errors of pavement layers on moduli backcalculating is discussed.The results show that the errors have great influence on moduli backcalculating.The subbase modulus is easily influenced and the subgrade modulus is basically not influenced by the thickness errors. The errors of backcalculated moduli will not exceed ±15% if the errors of pavement layer thickness are controlled within ±5%.
