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。
Asphalt pavement structure thickness and aggregate maximum nominal particle size ratio is an important factor affecting the quality of asphalt pavement. The results of numerical simulation in this study show that the revision of this ratio value in the 2004 version of the highway asphalt pavement construction specification is more reasonable than that of the 94 edition. However, The determination of this ratio needs more consideration and engineering practice. Combined with the numerical calculation results, the proposed values for various graded layer thicknesses and the maximum nominal particle size ratio are proposed.
