Abstract

The invention provides a frost crack prevention pavement construction material. The frost crack prevention pavement construction material comprises the following raw materials in parts by weight: cement, quartz weathering sand, quick lime, aluminum paste, gypsum, a stone cracking agent, an inhibitor and a water reducing agent. The dry material component of the frost crack prevention pavement construction material also comprises water. The invention also provides application of the frost crack prevention pavement construction material to pavement construction of a cold region. The cold region refers to a pavement positioned at the temperature of 40 DEG C below zero to zero DEG C in winter. The material disclosed by the invention is readily available, low in price and simple in process and can be made and used at any time.

Description

technical field [0001] The invention provides a construction material for antifreezing and cracking pavement and a preparation method thereof, which is applied to roadbed materials to prevent pavement cracking in winter. Background technique [0002] In cold winter, when the air temperature is often below minus 20 degrees, the main reasons for pavement cracking are: (a) The problem of water storage in large cracks is not easy to solve, so that the pavement is often in a frozen state. (b) It is difficult to find large-scale equipment on site to detect large-scale pavement, so that large-scale cracks freeze. In terms of road surface construction, the optimization of roadbed materials to prevent cracking of the road surface is an urgent problem to be solved. Contents of the invention [0003] On the basis of the above problems, the present invention provides a construction material for antifreezing and cracking pavement, which comprises the following raw materials in parts b...
