针对气候特点对新疆地区沥青路面层间处治进行了气候分区,结合各分区温度与降雨特征分别推荐了层间处治沥青材料.综合温度、面层厚度、纵坡与车辆载重等因素对层间工作状态的影响,提出了新疆地区半刚性基层沥青路面层间工作状态分级及典型影响因素取值.基于渗透试验和层间抗剪试验,得到了不同透层材料、不同洒布量下的渗透深度与抗剪强度,确定了不同透层材料最佳洒布量.采用直剪试验,得到了不同碎石洒布量、不同沥青材料、不同沥青洒布量下基面层间抗剪强度,确定了封层碎石与沥青的最佳洒布量.同时,研究了风吹砂对基面层间结合状况的影响,分别得到了干燥与饱水状态下,风吹沙污染量与基面层间抗剪强度的回归函数.
According to the climatic characteristics of Xinjiang asphalt pavement treatment of climate division, combined with the sub-district temperature and rainfall characteristics were recommended for the treatment of asphalt between the layers of material. Comprehensive temperature, surface thickness, longitudinal and vehicle load and other factors on the work of the interlayer The paper puts forward the classification of the working status of semi-rigid base asphalt pavement in Xinjiang and the typical influential factors.According to the permeability test and the interlaminar shear test, the infiltration depths And shearing strength, the best amount of spreading material for different layers of permeable material was determined.The direct shear test was used to obtain the shear strength of different materials, different asphalt materials, The influence of wind-blown sand on the bonding between the base and the floor was studied, and the relationship between the amount of wind and sand blown and the surface layer Regression function between shear strength.
