Preparation method of indirect coal liquefaction residue asphalt mixture
The invention relates to a preparation method of an indirect coal liquefaction residue asphalt mixture. The preparation method comprises the following steps: step 1, testing various performance indexes of indirect coal liquefaction residues, asphalt, aggregate and mineral powder; 2, determining the optimal use amount of asphalt in the asphalt mixture by adopting a Marshall design method; 3, replacing the fine aggregate with the indirect coal liquefaction residues in a single-mesh particle size and equal-volume manner to obtain aggregate doped with the indirect coal liquefaction residues; 4, respectively placing the aggregate doped with the indirect coal liquefaction residues, the mineral powder and the asphalt in a drying oven, and preheating according to a preset time and a preset temperature; and 5, pouring the preheated aggregate, asphalt and mineral powder in the step 4 into a mixing pot, and mixing to finally prepare the indirect coal liquefaction residue asphalt mixture. According to the method, high-added-value utilization of the indirect coal liquefaction residues can be achieved, waste is turned into wealth, the pavement performance of the mixture can meet the performance requirements of the hot-mix asphalt mixture, and the method has obvious economic benefits and social benefits.
本发明涉及一种煤间接液化残渣沥青混合料的制备方法，步骤一，测试煤间接液化残渣、沥青、集料、矿粉的各项性能指标；步骤二，采用马歇尔设计方法确定沥青混合料中沥青的最佳用量；步骤三，煤间接液化残渣以单一筛孔粒径、等体积的方式替换细集料，得到掺有煤间接液化残渣的集料；步骤四，将掺有煤间接液化残渣的集料、矿粉、沥青分别放置在烘箱内按照预设时间和预设温度进行预热；步骤五，将步骤四中预热后的集料、沥青、矿粉倒入拌合锅内拌合，最终制得煤间接液化残渣沥青混合料。本发明能够实现将煤间接液化残渣高附加值利用、变废为宝，混合料路用性能能够达到热拌沥青混合料的性能要求，具有明显的经济效益和和社会效益。
