The invention discloses a pavement structure adopting a warm-mixed ultrathin layer overlay and a construction method of the pavement structure, belongs to the technical field of pavement structures and construction, and solves the problems of environmental pollution and high energy consumption caused by adoption of a hot-mixed asphalt ultrathin wearing layer in the prior art. The pavement comprises an original pavement, a bonding waterproof layer and an ultra-thin overlay layer, the original pavement is subjected to disease treatment, the bonding waterproof layer is laid on the surface of the original pavement, the ultra-thin overlay layer is laid on the surface of the bonding waterproof layer, the ultra-thin overlay layer is a warm mixing ultra-thin overlay finished product mixture OGFC-5, and the asphalt-aggregate ratio of the ultra-thin overlay layer is 6.5%-7.0%. According to the invention, fuel oil for material production can be saved by 20-30%, emission of greenhouse gases can be reduced by about 50%, and emission of harmful gases such as asphalt smoke can be reduced by more than 80%; milling asphalt waste is not generated, the environment is protected, and the national green and environment-friendly policy is better met. The method is suitable for changing white cement pavements into black cement pavements, repairing and pre-curing asphalt pavements and building colored greenways.
本发明公开了一种采用温拌超薄层罩面的路面结构及其施工方法，属于路面结构及施工技术领域，解决了现有技术中采用热拌沥青超薄磨耗层污染环境、能源消耗大的问题。本发明包括原路面、粘结防水层和超薄罩面层，所述原路面经病害处理，所述粘结防水层铺设于原路面的表面，所述超薄罩面层铺设于粘结防水层的表面，所述超薄罩面层为温拌超薄罩面成品混合料OGFC～5，超薄罩面层的油石比为6.5％～7.0％。本发明可节省制料生产用燃油20％‑30％，减少温室气体排放50％左右，减少沥青烟等有害气体排放80％以上；不产生铣刨沥青废料，保护环境，更符合国家绿色环保政策。适用于水泥路面白改黑、沥青路面修复及预养护，以及彩色绿道建设。
