Abstract

The invention relates to cement concrete surface repairing material which is in particular applicable to the thin layer repairing of the cement concrete road surface. The invention consists of resin, portland cement, rapid hardening sulfur aluminium salt, dry river sand without soil, 40 to 70 item quartz sand, gray desert powder and swelling extender. The invention is divided into repairing material first component and repairing material second component during the actual use, the invention is evenly mixed when being used by cooperating with manual knifing or mechanical knifing. The usage method is cooperated with the use of the surface paint and the base paint when the repairing material is used. The use procedure also comprises the clearing preparation before the road surface repairing and the surface treatment after the repairing. The invention solves the problems that the repairing of the thin layer of the cement concrete road surface easily falls off and the durability is not good, simplifies the construction craftwork and assures that the traffic can be quickly recovered on the premise of the use capacities of the road surface.

Description

technical field

[0001] The invention relates to the development and application of a thin-layer repair material for cement concrete pavement surface, which is especially suitable for the rapid repair of salt-damaged pavement. Background technique

[0002] With the continuous improvement of national infrastructure, my country has gradually formed a national highway system with high-grade highways and expressways as the main body. By 2002, the national highway mileage reached 1.758 million kilometers, expressways 25,000 kilometers, and first-class highways. 27,400 kilometers, 197,000 kilometers of secondary roads. The number of highway bridges reached 300,000 with a length of 11.61 million meters. The road density reached 18.3 kilometers per hundred square kilometers. The depth of highway access has been further improved. There are 103 new townships and 3,890 administrative villages connected to roads. The proportion of townships and towns connected to roads in the country h...
