Abstract

The invention provides an intelligent bonding layer for a carpet type asphalt pavement as well as a preparation method and application of the intelligent bonding layer. The intelligent bonding layer for the carpet type asphalt pavement comprises a bonding material, an optical fiber material and a reinforced material, the optical fiber material is packaged in the reinforced material; the reinforcement material is a CFRP carbon fiber reinforced composite material, and the binding material is an asphalt thin layer and / or bi-component modified epoxy resin. The intelligent bonding layer for the carpet type asphalt pavement can meet the interlayer bonding requirement of the carpet type asphalt pavement, the bonding performance of the bonding layer is improved, and the interlayer stress state can be sensed. The invention further provides a preparation method and application of the intelligent bonding layer for the carpet type asphalt pavement, the preparation method provided by the invention is suitable for construction of the carpet type asphalt pavement, effective bonding between layers of the carpet pavement is facilitated, and meanwhile, a sensing function of paving the carpet pavement is realized.

Description

technical field [0001] The invention relates to the technical field of carpet-type asphalt pavement, in particular to an intelligent bonding layer for carpet-type asphalt pavement and its preparation method and application. Background technique [0002] Carpet asphalt pavement (Carpet asphalt pavement, referred to as CA) is a kind of curly asphalt pavement structure layer that can be prefabricated in the factory. . The construction site is paved like a carpet, which can realize rapid installation, removal and recycling on site, save a lot of construction time, improve maintenance efficiency, and quickly open up traffic. [0003] Carpet asphalt pavement adopts factory prefabrication technology. Since carpet prefabricated asphalt pavement is rolled and transported to the construction site, it is necessary to heat the bonding material and the bottom of the prefabricated pavement, and then it can be laid on the original pavement. This interlayer bonding state, which is similar...
