Abstract

The invention discloses a high-viscoelastic asphalt road viscous layer oil and a preparation method thereof. The components include distillate oil, petroleum resin, epoxy resin, thermoplastic elastomer, emulsifier and water. The invention provides a kind of high viscoelastic asphalt road viscous oil, which not only has two indicators of viscosity and elasticity significantly better than traditional common emulsified asphalt viscous oil, but also other technical indicators are better than traditional common emulsified asphalt Sticky layer oil belongs to a kind of high-performance sticky layer oil for asphalt roads. The invention solves the disadvantages that the traditional ordinary emulsified asphalt sticky layer oil has poor viscoelasticity and is easy to cause detachment and cracking between asphalt pavement layers. The use of the invention can effectively improve the bonding strength and shear strength between asphalt layers, prevent and delay the asphalt pavement from cracking, wrapping, rutting and other diseases and damages, significantly improve the service performance of the asphalt road, and prolong the service life of the asphalt road.

Description

technical field [0001] The invention relates to a high viscoelastic asphalt road viscous oil, which belongs to the technical field of road building materials, and also relates to a preparation method of the high viscoelastic asphalt road viscous oil. Background technique [0002] Asphalt road viscous layer oil is a kind of liquid material, its main purpose is to spread between the asphalt layer and the asphalt layer of the road, and between the asphalt layer and the cement concrete road surface to form a thin bonding layer, which is to make the upper and lower layers of asphalt road The structural layer or asphalt structural layer and the structure (cement concrete pavement, etc.) are completely bonded into a whole. In the construction of asphalt roads, if the following conditions are met, the sticky layer oil should be poured: ①The asphalt layer below the double-layer or three-layer hot-mix hot-pavement asphalt mixture pavement has been polluted before the upper layer is pa...
