现行沥青混凝土路面设计规范中以路表弯沉为主要设计指标,并以综合弯沉修正系数调整实测值与理论值之间的偏差。鉴于考虑的基层类型以半刚性基层为主,通过对现场试验路测试数据的分析,提出了新的F计算式,适用于厚沥青混凝土层路面结构形式。 Current asphalt concrete pavement design specifications to the road surface deflection as the main design indicators, and comprehensive deflection correction coefficient to adjust the deviation between measured and theoretical values. In view of the grass-roots type considered mainly semi-rigid grass-roots level, through the analysis of the test data of the field test road, a new F formula is proposed, which is suitable for the thick asphalt concrete pavement structure.
