High-strength asphalt concrete and preparation method thereof
The invention relates to the technical field of concrete, and provides high-strength asphalt concrete and a preparation method thereof.The asphalt concrete is prepared from, by weight, 18-24 parts of asphalt, 8-16 parts of cement, 80-100 parts of gravel, 20-30 parts of cellulose ester derivatives, 40-50 parts of medium sand and 50-60 parts of mineral fine powder; the cellulose ester derivative comprises cellulose acetate phthalate and cellulose acetate, and the weight ratio of the cellulose acetate phthalate to the cellulose acetate is (1: 9)-(9: 1). According to the technical scheme, the problem of poor mechanical property of asphalt concrete in related technologies is solved.
本发明涉及混凝土技术领域，提出了一种高强度沥青混凝土及其制备方法，沥青混凝土包括以下重量份的组分：沥青18~24份、水泥8~16份、碎石80~100份、纤维素酯类衍生物20~30份、中砂40~50份、矿物细粉50~60份；纤维素酯类衍生物包括醋酸邻苯二甲酸纤维素和醋酸纤维素，醋酸邻苯二甲酸纤维素和醋酸纤维素的重量比为1:9~9:1。通过上述技术方案，解决了相关技术中沥青混凝土力学性能差的问题。
