Track-free asphalt pavement and construction method
The invention relates to a rut-free asphalt pavement and a construction method, and relates to the technical field of road construction, the rut-free asphalt pavement comprises a stable layer laid on a roadbed and an asphalt concrete layer laid on the stable layer; the thickness ratio of the stable layer to the asphalt concrete layer is (1-2.5): 1; the stable layer is prepared from the following raw materials in parts by weight: 85-100 parts of gravel and 35-50 parts of petroleum asphalt; the asphalt concrete layer is formed by paving asphalt concrete on the stable layer and curing, and the asphalt concrete comprises the following raw materials in parts by weight: 8-15 parts of petroleum asphalt, 65-80 parts of mineral aggregate, 6-12 parts of epoxy resin, 3-10 parts of an asphalt modifier and 0.5-2 parts of a curing agent. The asphalt concrete layer is effectively restrained from shearing, pushing and sliding, so that the pavement is prevented from being deformed, and the rut resistance of the pavement is improved.
本申请涉及一种无车辙沥青路面及施工方法，涉及道路施工技术的领域，包括铺设于路基上的稳定层和铺设于所述稳定层上的沥青混凝土层；所述稳定层与所述沥青混凝土层的厚度比为（1～2.5）：1；所述稳定层由包含以下重量份的原材料制成：碎石85‑100份，石油沥青35‑50份；所述沥青混凝土层由沥青混凝土铺设于所述稳定层上固化后形成，所述沥青混凝土包含以下重量份的原材料：石油沥青8‑15份，矿物集料65‑80份，环氧树脂6‑12份，沥青改性剂3‑10份，固化剂0.5‑2份。本申请具有有效束缚沥青混凝土层不发生剪切推移滑动、进而阻止路面出现变形、提升路面的抗车辙能力的效果。
