Abstract

The invention discloses an interlayer structure construction method of an asphalt pavement. The interlayer structure construction method includes the following steps of cleaning an under bearing layer of the pavement; sprinkling rubber asphalt; sprinkling rubbles; and rolling into the shape. The interlayer structure construction method of the asphalt pavement has the advantages of being high in bonding strength between layers, good in water tightness, excellent in anti-shearing performance, deferring reflection cracks, convenient to construct, low in comprehensive cost and the like. By adoption of the interlayer structure construction method of the asphalt pavement, construction work can be done without closing to traffic or closing to traffic for a short term, therefore, the interlayer structure construction method of the asphalt pavement can not only be suitable for a bonding layer between asphalt surfaces of newly-built roads, but also particularly suitable for repairing and maintaining projects for asphalt surfaces of urban roads.

Description

technical field

[0001] The invention relates to the technical field of traffic survey, in particular to a construction method for an asphalt pavement interlayer structure. Background technique

[0002] Asphalt pavement structure is the main pavement structure type of high-grade highways in my country, and generally consists of asphalt surface layer, base layer, subbase layer and cushion layer. The asphalt pavement of high-grade highways such as expressways, first-class highways, urban expressways, and trunk roads generally consists of three layers, which are divided into surface layer, middle layer and bottom layer, and are structures that directly bear the repeated action of vehicle loads and the influence of natural factors. layer. According to the change of pavement structure strength and load stress with depth, different asphalt mixture gradations are selected for the three-layer structure of asphalt pavement, so that the whole asphalt pavement has better road performan...
