Problems solved by technology

The raw materials of cement concrete are easy to obtain, normal temperature construction, non-toxic, good temperature resistance, no rutting, water damage and other problems, good durability, long service life; but at the same time, there are poor driving comfort, high noise, The maintenance period is long, and there are defects such as cuts on the road surface
The surface of asphalt concrete pavement is smooth and seamless, with little driving vibration, low noise, fast open traffic, easy maintenance, but poor durability, prone to rutting, water damage, cracking, and bagging and other diseases
At the same time, since the asphalt pavement requires thermal construction, it consumes a lot of energy, which will also cause environmental problems to a certain extent.

Abstract

The invention relates to a cold construction color cementing material for resin concrete. According to the invention, a composite epoxy resin used as a substrate is prepared by mixing a bisphenol A type epoxy resin and a flexible epoxy resin and subjecting an obtained mixture to modification by a flexibilizer, a coupling agent and an anti-ageing agent; a curing agent is prepared by modifying a conventional curing agent with a dispersant and a defoaming agent; the cementing material has obviously superior high temperature performance, low temperature performance, water stability and fatigue resistance to those of common asphalt and SBS modified asphalt; the cementing material in a liquid state needs no extra heating in the processes of mixing, transporting, paving and compacting, according with requirements for energy saving and low carbon; when the prepared resin concrete for cold construction is used for laying of a pavement, a curing period is short, and traffic is rapidly opened; an inorganic pigment or organic pigment is added for preparation of the color cementing material which is applicable to pavements with different functional requirements; composition materials are easily available, and the cold construction color cementing material is prepared by using a conventional method and is easy for large scale popularization.

Description

technical field [0001] The invention relates to a cementing material for concrete, in particular to a cementing material for cold construction colored resin concrete. Background technique [0002] There are two main types of pavement materials that are commonly used at present, namely cement concrete and asphalt concrete. The raw materials of cement concrete are easy to obtain, normal temperature construction, non-toxic, good temperature resistance, no rutting, water damage and other problems, good durability, long service life; but at the same time, there are poor driving comfort, high noise, The maintenance period is long, and the road surface has shortcomings such as cuts and seams. Asphalt concrete pavement has flat surface without joints, low driving vibration, low noise, fast open traffic, easy maintenance, but poor durability, prone to rutting, water damage, cracking and wrapping and other diseases. At the same time, since the asphalt pavement requires thermal const...
