Abstract

The invention provides a quick-hardening low-shrinkage colored cement grouting material and a construction method thereof. The colored cement grouting material mainly comprises the following raw materials in parts by weight: 100 parts of white cement, 8-20 parts of silica fume, 15-25 parts of slag powder, 20-35 parts of ground calcium carbonate powder, 25-40 parts of quartz sand, 0.75-1.80 parts of an excitant, 0.10-0.25 part of a water reducer, 0.008-0.020 part of a defoamer, 3-7 parts of an expanding agent, 0.04-0.11 parts of cellulose ether, 3.6-8.0 parts of pigment and 55-80 part of water.The strength of the cement grouting material is rapidly increased, the cement grouting material has the advantages of being good in workability and small in shrinkage deformation, and the high-temperature anti-rutting performance of a semi-flexible pavement is improved; and the product has the characteristics of adjustable color and simple construction process.

Description

technical field [0001] The invention belongs to the technical field of road engineering, and in particular relates to a fast-hardening and low-shrinkage colored cement grouting material and a construction method thereof. Background technique [0002] Asphalt concrete pavement is the main pavement form of urban roads in my country, but the bearing capacity and stability of asphalt concrete pavement are greatly affected by temperature. In the case of high temperature in summer, the viscosity of asphalt in the asphalt mixture decreases, the cohesion between aggregates weakens, and the strength and deformation resistance of the pavement decrease. At this time, under the load of the vehicle, the asphalt concrete pavement is prone to rutting deformation, especially Under the action of vertical and horizontal forces, asphalt concrete pavement is prone to deformation and damage such as rutting, pushing and wrapping during the stages of vehicle starting, acceleration and braking, etc...
