Construction method of heat insulation temperature reduction type asphalt concrete wearing layer

Abstract

The invention relates to a construction method of a heat insulation temperature reduction type asphalt concrete wearing layer. The method comprises the steps of (1), raw material selection; (2), material cooperation ratio designing: wasted ceramic tile recycled materials with equal volumes are adopted, namely equivalent granule group natural mineral aggregates in a conventional asphalt mixture arereplaced with the aggregates with two particle diameter levels of 4.75 mm and 9.5 mm, and the doping amount of the wasted ceramic tile recycled doping material is controlled to be 40%-60%; (3), heatinsulation temperature reduction type asphalt concrete wearing layer construction: 3.1), a synchronously construction method in which coating oil cloth spraying and mixture spreading are conducted isadopted for the heat insulation type asphalt concrete wearing layer with doped ceramic tile recycled materials; 3.2), optical-thermal reflection coating layer construction layer is conducted; 3.3), optical-thermal reflection coating layer caring is conducted; 3.4), a road is opened to traffic. The method is suitable for (high temperature) rutting resisting structural layer construction of variousroads and urban roads, particularly for the newly building or overlaying construction of a rutting resisting surface layer or a wearing layer of an asphalt road surface of a road section where ruttingdamage frequently occurs of heavy traffic, intersection and the like.

Description

technical field [0001] The invention belongs to the technical field of road surface construction in road engineering, and in particular relates to a construction method of a heat-resisting and cooling-type asphalt concrete wearing layer. Background technique [0002] The cause analysis of rutting shows that high temperature is the most direct cause of rutting on asphalt pavement. Because of this, when solving the rutting problem of asphalt pavement, the technical measures to improve the high temperature stability of asphalt mixture are mainly adopted. Engineering practice has proved that due to the temperature-sensitive nature of asphalt materials, these passive measures have not fundamentally solved the problem of high-temperature rutting on asphalt pavement, and the thermal stability of asphalt pavement is still serious.
