Highway pavement base cement stabilized macadam and processing method thereof
The invention discloses highway pavement base cement stabilized macadam and a processing method thereof. The highway pavement base cement stabilized macadam comprises aggregate, natural macadam, cement mortar, an expanding agent and asbestos powder, the raw materials are as follows in parts by weight: 70-90 parts of aggregate, 60-80 parts of natural gravel, 10-20 parts of cement mortar, 2-4 partsof expanding agent and 6-8 parts of asbestos powder. The aggregate is crushed aggregates obtained by crushing and screening waste cement concrete; the particle size of the aggregate is set to be 0.1-25mm; the cement mortar is composed of cement and water. The composition ratio of the cement to the water is 4: 10; wherein the cement is set to be ordinary Portland cement, the initial setting time ofthe cement is longer than 3 hours, the final setting time of the cement is longer than 6 hours, an expanding agent is set to be a concrete expanding agent, the natural macadam is a product obtained by crushing and sieving macadam, and the particle size distribution of the natural macadam is 9-31 mm. According to the highway pavement base cement stabilized macadam and the processing method thereof, waste can be recycled, and the ventilation effect can be guaranteed.
本发明公开了一种公路路面基层水泥稳定碎石及其加工方法，包括骨料、天然碎石、水泥砂浆、膨胀剂和石棉粉，各原料按重量份计为：骨料70‑90份、天然碎石60‑80份、水泥砂浆10‑20份、膨胀剂2‑4份和石棉粉6‑8份，所述骨料设置为废弃水泥混凝土经破碎、筛分后得到的碎料，且骨料的粒径设置为0.1至25毫米，所述水泥砂浆由水泥和水组成，水泥和水的组成比例为4比10，所述水泥设置为普通硅酸盐水泥，水泥的初凝时间大于3小时，水泥的终凝时间大于6小时，所述膨胀剂设置为混凝土膨胀剂，所述天然碎石由碎石经过粉碎和过筛的产物，天然碎石的粒径分布为9‑31毫米。该公路路面基层水泥稳定碎石及其加工方法，不仅能够废物再利用，还能保证透气的作用。
