抗车辙能力与沥青混凝土混合料的体积构成

Rut resistance and volumetric composition of asphalt concrete mixtures

以混合料抵抗力的概念给出了用于估计混合料抗车辙能力的模型,为了证实所提出模型的可用性,把MN/Road,Wes Track和NCAT Test Track的车辙数据引入了该模型,并用抵抗力、Ndesign和相关现场密度作为预测变量,这个模型可被用来分析混合料构成的变化、结合料的等级和压实对抗车辙能力的影响。

This paper describes a model for estimating mixture rut resistance using the ooncept of mixture resistivity, to verify the usefulness of the proposed model field rotting data from MN/Rcad,WesTrack and the NCAT Test Track were modeled, using resisfivity,Ndesign and relative field density as predictor variables. This model was used to analyze the effects of changes in mixture composition, binder grade,and compaction on rut resistance.
