CMCA ultrathin wearing layer pavement and construction method thereof
The invention discloses a CMCA ultrathin wearing layer pavement and a construction method thereof. The CMCA ultrathin wearing layer pavement comprises a crack grouting treatment layer, a high-strength bonding layer and a CMCA mixture layer from bottom to top. A high-strength bonding layer material is evenly sprayed on the original road surface subjected to disease treatment, and the spraying amount is 0.3-0.6 kg/m < 2 >; after the surface of the high-strength bonding layer is dried, a CMCA mixture layer with the thickness of 1.5-2.5 cm is uniformly paved; and opening traffic after the surface of the CMCA mixture is dried. Compared with an existing cold-mixing and cold-paving ultrathin overlay maintenance technology, the technology has the advantages that the skid resistance of a wearing layer is greatly improved, the service life of the wearing layer is greatly prolonged, meanwhile, the bonding strength is also remarkably improved, the problems of falling, peeling, skid resistance attenuation, crack reflection and the like of existing cold-mixing and cold-paving ultrathin overlay large stone materials are effectively solved, and the service life of the cold-mixing and cold-paving ultrathin overlay is prolonged. Meanwhile, the high-viscosity and high-elasticity ultrathin hot overlay has the advantages of long service life, high bonding strength, good water damage resistance and the like.
本发明公开了一种CMCA超薄磨耗层路面及其施工方法。CMCA超薄磨耗层路面自下而上包括：裂缝灌浆处置层、高强粘结层、CMCA混合料层。在进行病害处置过后的原路面，均匀喷洒高强粘结层材料，喷洒量为0.3‑0.6kg/m2；待高强粘结层表干后，均匀摊铺1.5‑2.5cm厚的CMCA混合料层；待CMCA混合料表干后，开放交通。该技术相比于现有的冷拌冷铺超薄罩面养护技术而言，极大地提升了磨耗层的抗滑性能和使用寿命，同时粘接强度也得到了显著提升，有效的解决了目前冷拌冷铺超薄罩面大石料脱落、起皮、抗滑性衰减以及裂缝反射等问题，同时具备高黏高弹超薄热罩面寿命长、粘接强度高、抗水损性能佳等优势。
