Abstract

The invention provides a colorized automatic-flow-into semi-flexible pavement mortar which can be filled into the apertures of the structural layer of a large-aperture asphalt mixture. The mortar comprises 30-50wt% of cement, 20-40wt% of sand, 2-4wt% of an organic binder, 10-25wt% of an active filler, 3-5wt% of an alkali shrinking agent, 0.3-0.6wt% of a water reducer, 0.1-0.5wt% of an early-strength agent, 2-5wt% of a pigment, 0.2-0.3wt% of a dispersant, 5-10wt% of a rapid hardening agent, and water accounting for 20-30% of the total weight of the above components, wherein the pigment is a chromium system and iron oxide system powdery pigment and preferably comprises 90% of the pigment having a particle size below 6-9mum and 50% of the pigment having a particle size below 2-5mum, and the preferable density of the pigment is 4-5g / cm<3>. The mortar can well guarantees all proper performances of the colorized automatic-flow-into semi-flexible pavement mortar, and smoothly realizes the mortar colorization on the premise of the proper fluidity and compressive strength, so colorized pavements having various colors can be obtained as needed.

Description

technical field [0001] The invention relates to a road mortar, in particular to a road mortar that can be filled in the pores of a large-pore asphalt mixture structure layer, and more particularly relates to a colored mortar that can be filled in the pores of a large-pore asphalt mixture structure layer Colored self-flowing road mortar. Background technique [0002] Semi-flexible pavement is a pavement formed by pouring special cement-based mortar into a large-void matrix asphalt mixture (void ratio as high as 25%-30%). Semi-flexible pavement has the characteristics of higher flexibility than cement concrete pavement and higher rigidity than asphalt concrete pavement. It has excellent road performance such as anti-rutting, anti-moving, reducing expansion and contraction, and improving stress relaxation of pavement materials. It also has oil resistance. , acid resistance, heat resistance, water resistance, anti-skid and landscape decoration effects and other functions, semi-...
