Embodiment 1

[0011] Road maintenance cold joint sealant is composed of the following components according to the following weight ratios:

[0012] Modified asphalt: Paint thinner: Chloroprene: Beard oil=120:15:30:20.

[0013] Described paint thinner is dichloromethane.

[0014] The preparation method of the road maintenance cold joint sealant of the present invention is as follows: firstly, the modified asphalt is dissolved at high temperature, and then the above-mentioned raw materials are taken in proportion and fully mixed and stirred evenly.

[0015] The method of using the road maintenance cold caulking glue of the present invention is as follows: before construction, the inside of the crack is cleaned up, and then the crack is blown clean with a seam blowing machine and the crack is kept dry. Use a special caulking machine to pour carefully and slowly along the crack until it is leveled.

Embodiment 2

[0017] Road maintenance cold joint sealant is composed of the following components according to the following weight ratios:

[0018] Modified asphalt: Paint thinner: Chloroprene: Beard oil=80:35:50:40.

[0019] Its preparation method is with embodiment 1.

Embodiment 3

[0021] The road maintenance cold joint sealant is composed of the following components in the following parts by weight ratio:

[0022] Modified asphalt: paint thinner: chloroprene: butternut oil=90:30:45:35.

[0023] Its preparation method is with embodiment 1.

Abstract

The invention relates to cold gap-filling glue for road maintenance, which is characterized by comprising the following components in parts by weight: 80-120 parts of modified asphalt, 15-35 parts of paint thinner, 30-50 parts of chloroprene and 20-40 parts of siritch. The cold gap-filling glue for road maintenance can be directly used without being heated in low-temperature environment, still has good ductibility, wearing resistance, shock resistance and crack resistance at low temperature, has good heat resistance, anti-melting viscous-flow performance, ageing resistance, and the like at high temperature and has optimal adhesivity with an asphalt mixing material in a gap for effectively repairing in a long period. The cold gap-filling glue for road maintenance does not need to be heated, has safe operation, convenient maintenance and no environmental pollution and can be directly and deeply penetrated into a roadbed. Compared with hot gap-filling glue, the road maintenance cold gap-filling glue saves 20-50 percent and saves materials very much.

Description

technical field [0001] The invention relates to a caulking glue, in particular to a cold caulking glue suitable for road maintenance. Background technique [0002] At present, due to the increasing number of private cars, the damage suffered by the road surface is also increasing, so the road maintenance department should often repair the cracks and potholes on the road surface in time. However, the currently used caulking glue has the following problems: when the temperature is below zero, the caulking glue needs to be heated before it can be used, which causes trouble for the road maintenance department in the maintenance and use process, and wastes manpower and material resources. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a cold joint sealant for road maintenance, which can be used directly without heating when the temperature is very low, has stable performance and is easy to use. [0004] In order to ...
