Extremely-thin wearing layer mixture for preventive maintenance of road and preparation and construction methods of extremely-thin wearing layer mixture
The invention relates to the technical field of road maintenance materials, in particular to an ultra-thin wearing layer mixture for preventive maintenance of a road as well as a preparation method and a construction method of the ultra-thin wearing layer mixture. The wearing layer mixture is prepared from wear-resistant aggregate, I-D modified asphalt, limestone mineral powder, an epoxy resin latent curing agent and a special biological additive. The construction method of the wearing layer mixture comprises the steps that the second-order water-based resin asphalt serving as a bonding layer material is sprayed firstly, then the ultra-thin wearing layer mixture is paved after the surface of the bonding layer material is dried, and the final forming thickness is 1.2-2 cm. The wearing layer mixture disclosed by the invention is simple in production process, simple, convenient and efficient in construction, relatively thin in forming thickness, environment-friendly and practical, and has ideal industrialization value. The wearing layer mixture is excellent in high and low temperature resistance and high in fatigue cracking resistance, the forming thickness can be selected according to the rut damage degree of the pavement for corrective maintenance, and the wearing layer mixture can also be used for preventive maintenance of the asphalt pavement.
本发明涉及道路养护材料技术领域，尤其涉及一种用于道路预防性养护的极薄磨耗层混合料及其制备和施工方法。本发明磨耗层混合料由耐磨骨料、I‑D改性沥青、石灰岩矿粉、环氧树脂潜伏型固化剂和特种生物添加剂制成。本发明磨耗层混合料的施工方法为先洒布作为粘结层材料的二阶水性树脂沥青，然后在粘结层材料表干后摊铺极薄磨耗层混合料，最终成型厚度为1.2‑2cm。本发明磨耗层混合料生产工艺简单、施工简便高效、成型厚度较薄，环保实用，具有理想的产业化价值。本发明磨耗层混合料耐高低温性能优异，抗疲劳开裂能力强，可根据路面车辙病害程度选择成型厚度进行矫正性养护，也可用于沥青路面的预防性养护。
