Problems solved by technology

However, currently, for example, the machine-made sand used to replace river sand is affected by the process, and its particle size distribution is often poor
The crushed stone or the main aggregate is mainly machine-made material, and the controllability of particle gradation is relatively poor.

Abstract

The invention discloses a water-retaining semi-flexible composite pavement injection material and a preparation method thereof. The water-retaining semi-flexible composite pavement injection material has good liquidity, can be automatically filled into an asphalt mixture of a machine body and further has good water-retaining property, relatively good durability and aging resistance, and meanwhile, a heat island effect can be effectively reduced.

Description

technical field [0001] The invention relates to a water-retaining semi-flexible composite pavement injection material and a preparation method thereof. Background technique [0002] my country's existing road pavement can be divided into two categories, namely cement concrete pavement and asphalt concrete pavement. Cement concrete pavement materials have the characteristics of strong deformation resistance, long service life and low daily maintenance costs. However, this kind of pavement has a joint structure, which leads to poor driving comfort and difficult repair after the pavement structure is damaged. [0003] Asphalt concrete pavement has the characteristics of no joints, good road surface smoothness, and comfortable driving. However, asphalt, as a flexible material, is easily affected by ambient temperature and vehicle load. Among them, under high temperature conditions in summer, the asphalt pavement structure layer is prone to form ruts, potholes, waves, etc.; and ...
