Anti-aging asphalt concrete and preparation method thereof
The invention relates to the field of concrete, and particularly discloses aging-resistant asphalt concrete and a preparation method thereof. The aging-resistant asphalt concrete mainly comprises the following raw materials in parts by mass: 70-80 parts of gravels, 20-30 parts of stone chips, 5-8 parts of mineral powder, 1-3 parts of cement and 10-15 parts of modified asphalt. The preparation method comprises the following steps: step 1, weighing the gravels, the stone chips and the montmorillonite according to the mass, and stirring and drying in a drying barrel to obtain a dried mixture; 2, putting the dried mixture into a mixing cylinder, heating the modified asphalt, adding the modified asphalt into the mixing cylinder, and stirring to obtain an asphalt mixture; 3, putting cement, triterpenoid saponin and sodium lignin sulfonate into the mixing cylinder to be stirred; and 4, adding mineral powder into the mixing cylinder, and uniformly mixing to obtain the aging-resistant asphalt concrete. The aging-resistant asphalt concrete disclosed by the invention can be used for paving a pavement and has excellent aging-resistant performance.
本申请涉及混凝土领域，具体公开了一种耐老化沥青混凝土及其制备方法。一种耐老化沥青混凝土，按质量份数计，其原料主要包括70‑80份碎石，20‑30份石屑，5‑8份矿粉，1‑3份水泥，10‑15份改性沥青；其制备方法为：步骤一，按质量称取碎石、石屑、蒙脱土在烘干桶内进行搅拌烘干，得到干燥的混合料；步骤二，将干燥的混合料放入拌和缸中，将改性沥青加热，加入拌和缸中进行搅拌，制得沥青混合料；步骤三，将水泥、三萜皂甙、木质素磺酸钠放入拌和缸中进行搅拌；步骤四，再向拌和缸中加入矿粉，混合均匀后即可得到耐老化沥青混凝土。本申请的耐老化沥青混凝土可用于铺设路面，其具有优良的耐老化性能。
