本文依托G204日照段的改建工程,确定了高性能抗车辙沥青混合料的配合比,并验证了高性能抗车辙沥青混合料的高温抗车辙、强度等性能,并对抗车辙剂应用路段进行了跟踪检测。试验结果表明,高性能抗车辙剂可显著提高热拌沥青混合料的高温抗车辙性能及强度,并充分保证沥青混合料的水稳定性与低温抗裂性;工程跟踪观测结果表明,热拌沥青混合料中添加高性能抗车辙剂,不会增加施工工艺的复杂程度,是一种简单易操作的技术,具有重要的推广应用价值。
This paper relies on the development of G204Part day, determined the mix proportion of high performance anti-rutting asphalt mixture, and verified the anti-rutting, strength and other properties of high-performance anti-rutting asphalt mixture, and tracked the rutting application section Detection. The test results show that the high-performance anti-rutting agent can significantly improve the high temperature rutting resistance and strength of the hot mix asphalt mixture and fully ensure the water stability and low temperature crack resistance of the asphalt mixture. The engineering tracking observation shows that the hot mix asphalt Adding high-performance anti-rutting agent mixture will not increase the complexity of the construction process, is a simple and easy to operate technology, has an important application value.
