RAP的品质和性能直接影响热再生混合料的品质和性能。RAP的回收、贮运、加工质量是影响厂拌热再生沥青混合料技术性质和质量品质的重要环节,回收时不得混入杂物,使用前应通过破碎并筛分成不同粒级的RAP成品。根据料源的不同,分别检测成品RAP的油石比、回收沥青粘度、回收矿料级配及矿粉含量。通过建立拌和站管理台账,完善管理措施,保证再生混合料产品的质量和技术品质。
The quality and performance of RAP directly affects the quality and performance of the heat-regenerated mixes. RAP recovery, storage and transportation, processing quality is an important part of the technical nature and quality of the hot mix recycled asphalt mixture. Recycling shall not be mixed with debris. Before use, the RAP shall be crushed and sieved into different size RAP products. According to the different sources, the ratio of the asbestos in finished RAP, the viscosity of bitumen recovered, the grade of ore material recovered and the content of ore powder were tested respectively. Through the establishment of mixing station management ledger, improve management measures to ensure the quality of recycled mixture of products and technical quality.
