Heat reflection type block gravel slope protection roadbed and construction method
The invention provides a heat reflection type block gravel slope protection roadbed and a construction method, and relates to the technical field of infrastructure construction. According to the method, heat reflection type coatings of different colors are sprayed on a road surface and a side slope block gravel protection slope respectively so as to achieve the effect of protecting permafrost under an asphalt road surface in a permafrost region; a deep-color near-infrared heat reflection type coating is uniformly sprayed on the road surface; block gravels with gray epoxy resin coatings are laid on the two sides of the roadbed body. According to the roadbed, the reflection characteristic of the heat reflection type coating is utilized, under the condition that the road surface is kept in a dark color, absorption of the road surface and the rubble protection slope to solar radiation is reduced from the source, and the cooling capacity of rubble is further enhanced; and meanwhile, the weathering resistance of the heat reflection type coating is utilized to reduce the weathering effect of the block gravels under extremely complex conditions, so that the durable cooling of the permafrost under the asphalt pavement is realized, the stability of the subgrade (such as Qinghai-Tibet Plateau and arctic region) in the permafrost region is improved, and the smoothness of the road is ensured.
本申请提供一种热反射型块碎石护坡路基及施工方法,涉及基础建设技术领域。该方法是在路面和边坡块碎石护坡上分别喷涂不同颜色的热反射型涂层,以期起到保护多年冻土区沥青路面下伏多年冻土的作用:在路面上均匀喷涂一层深色近红外热反射型涂层;在路基主体两侧铺设有灰色环氧树脂类涂层的块碎石。该路基利用热反射型涂层的反射特性,在保持路面为深色的条件下,从源头上减少路面和块碎石护坡对太阳辐射的吸收,进一步增强块碎石的降温能力,同时利用热反射型涂层的抗风化特性以减少块碎石在极端复杂条件下所经受的风化作用,实现对沥青路面下伏多年冻土的持久降温,以提高多年冻土区路基(如青藏高原和北极地区)的稳定性,确保道路的畅通。
