低温工况下沥青路面压实特性研究
Study on Compaction Characteristics of Asphalt Pavement under Low Temperature
摘要
Abstract
In order to study the influence of temperature on compaction degree,theory density change rule of Marshall specimens was studied under different temperatures and compaction times.A mixture temperature lost model was established based on heat conduction theory to study asphalt mixture heat losing under low temperature,this model was also verified by observation data.The results show that:asphalt mixture was difficult to be compact to 98％ degree under 100 ℃.As thin as the pavement was,the temperature distributed more scattered and the compaction become more hard.Thickness of pavement decreases from 10 cm to 4 cm by 2 cm grads,the effective rolling time decreases by 9.7％,25％,24％.关键词
