中文摘要：

沥青混合料路面结构层厚与集料最大公称粒径的比例是影响沥青路面质量的重要因素。本研究的数值模拟计算结果认为，公路沥青路面施工技术规范2004版中对这一比例值的修改较之94版的规定更为合理，但对于近年来流行的嵌挤密实型等粗级配，这一比例的确定还需更多的考虑与工程实践。结合数值计算结果，研究提出了各类级配层厚与最大公称粒径比例的建议值。

英文摘要：

The proportion particle size of asphalt concrete Numerical simulation results o Specification for Construction a between the construction thickness of structure course and the maximum is a significant factor that affects the quality of asphalt concrete pavement. f the research show that modification about the proportion in Standard nd Acceptance of Highway Asphalt Pavements is reasonable. And for the compacted interlocked gradation, determination of the proportion requires more consideration and practices. Further, the proposed proportions for each type of gradation are presented on the basis of the research.
