摘要
设计了12组AC-16沥青混合料,对其高温稳定性进行了试验研究,根据分形理论和车辙试验结果,建立了分形维数与高温稳定性能评价指标的相关方程,利用该方程预测AC-16沥青混合料的高温稳定性,可减少试验次数,为工程设计提供参考。
Twelve groups of AC-16 asphalt mixtures were designed and their high temperature stability was studied.Based on fractal theory and rut test results,the correlation equation of fractal dimension and high temperature stability evaluation index is established.This equation can be used to predict the high temperature stability of AC-16 asphalt mixture,which can reduce the number of tests and provide reference for engineering design.
