摘要
针对模拟机场道面沥青混凝土靶板材料没有具体参考规范,提出了模拟机场道面的沥青混凝土靶板材料参数.沥青混凝土靶板材料采用连续级配的中粒式密实式沥青混合料,矿料最大直径为16mm,通过2.36mm筛孔的数量为40%～50%,2%的水泥作为填料.沥青材料选用AH-70标号的石油沥青,沥青用量4.4.对比表明,沥青混凝土靶板材料与机场沥青道面的性能指标接近,可为模拟机场道面沥青混凝土靶板提供技术支撑.
For lack of specific reference specification of asphalt concrete target material of simulated airport runway, the corresponding parameters are put forward. Asphalt concrete target material consists of grain type in dense asphalt mixture with continuous gradation of aggregate, the ore maximum diameter is Ф16 ram, the quantity through 2. 36 mm sieve is 40% ～ 50%, 2% cement as a filler. AH-70 grade asphalt is selected as asphalt material, asphalt content is 4. 4. Results show that the specifications of target material close to that of asphalt airport runway, which provides technical support for asphalt concrete target material of simulated airport runway.
