摘要
结合新疆克拉玛依石化大道和昌盛路工程实例,通过50#硬质沥青、集料及混合料的路用性能试验及检测来评价KLM-50#沥青的高温性能。试验结果表明对于夏季炎热地区的高等级公路沥青路面表面层可采用改性沥青。而中、下面层可以采用高温性能优良的硬质沥青体现抗车辙性能。
This paper concentrates on assessing high-temperature property of asphalt KLM-50# through the example of hard asphalt KLM50# to Shihua Aveand Chang-Sheng Road in Karamay The assessing is based on the experiment and research on pavement performance of asphalt KLM50# aggregale and mixture. The result shows that modified asphalt can be applied in the asphalt pavement surface layer of high-grade highway in summer parched area. And the hard asphalt with high-temperature property can be applied to the mid-layer and sub-layer to show its anti-rutting property.
