Problems solved by technology

[0002] Asphalt pavement is widely used for its smoothness, good driving comfort and low noise, but it is easy to soften in summer, easy to form ruts, and easy to be brittle and damaged in winter
Furthermore, asphalt pavement has poor aging resistance, and after several years of use, aging cracks and damage will occur, so it is not durable enough

Embodiment Construction

[0013] When preparing cement mortar, river sand or sea sand with good wear resistance is selected as aggregate, road cement or ordinary cement mixed with granulated blast furnace slag is selected as cementitious material, finely ground slag is selected as mineral admixture, and Tap water is used as mixing water for cement mortar. In order to improve the viscosity and ease of scraping of cement mortar, an appropriate amount of polymer such as resin is added.

[0014] Use a mortar mixer to mix the cement mortar. After mixing evenly, it can be scraped evenly and repeatedly on the asphalt road surface to make the final thickness 4-6mm, and then moisturize and maintain until the cement mortar hardens to reach the design strength. , the asphalt mixture-cement mortar composite pavement is formed, which can be opened to traffic.

Abstract

The invention discloses an asphalt mixture-cement mortar composite pavement, which belongs to the field of road engineering. A cement mortar protection layer is coated on the surface of an asphalt pavement to protect the asphalt pavement. The technology easily solves the problems that the asphalt pavement is easily softened in summer and cracked in winter, obviously prolongs the service life of the surface of the asphalt pavement and is used for road construction engineering.

Description

technical field [0001] This application belongs to Road Works. Background technique [0002] Asphalt pavement is widely used for its smoothness, good driving comfort, and low noise. However, it is easy to soften and form ruts in summer, and it is easy to be brittle and cracked in winter. Furthermore, asphalt pavement has poor aging resistance, and after several years of use, aging cracks and damage will occur, so it is not durable enough. Therefore, we should carry out technological transformation on the asphalt pavement to solve its existing problems. Contents of the invention [0003] The purpose of the present invention is to improve its anti-rutting ability and durability under the premise of ensuring good driving comfort on asphalt pavement. The technical scheme is as follows: [0004] 1. Prepare cement mortar with high viscosity and easy scraping. [0005] 2. On the asphalt pavement paved by conventional methods, scrape and coat cement mortar repeatedly and evenly...
