Abstract

The invention discloses a rapid repairing material for various road types and a construction and application method thereof. The repairing material comprises the following raw materials: 30%-60% of dicyclopentadiene, 1%-10% of a copolymer, 10%-40% of a functional filler A, 0-35% of a functional filler B, 0.01%-0.1% of a polymerization regulator, 1%-5% of an anti-ageing agent, 1%-3% of a cosolvent and 0.01%-0.1% of a solidifying agent, wherein the solidifying agent is a ruthenium-carbene catalyst. The construction and application method comprises the following steps: cleaning a to-be-repaired pavement or part; evenly mixing dicyclopentadiene, the copolymer, the functional filler A, the functional filler B, the polymerization regulator, the anti-ageing agent and the cosolvent to prepare a filler mixing solution; mixing the solidifying agent with the cosolvent to prepare a solidifying agent solution; fully mixing the filler mixing solution with the solidifying agent solution and then quickly feeding into the to-be-repaired part; controlling solidification to be finished within 1-60 minutes, wherein the solidification speed can be adjusted by adjusting the amount of the solidifying agent and / or the polymerization regulator; and rubbing down a repairing corner angle or a juncture after solidification is ended. The road repairing material disclosed by the invention is good in mechanical property, short in solidification time and simple to construct.

Description

technical field [0001] The invention belongs to the technical field of road maintenance, and in particular relates to a quick repair material for various types of roads and a construction and use method thereof. Background technique [0002] The pavement of cement concrete roads and asphalt roads is the main structural form of expressways, bridges, and urban roads. Under long-term traffic loads and environmental influences, cracks, potholes, potholes, and wrong platforms will appear on the roads to varying degrees. If it is damaged, if it is not repaired in time, it will have serious harm to the smooth operation of road traffic and the safety of drivers and pedestrians. Therefore, it is of great significance to the society to quickly repair the defects of the road. [0003] The existing road repair materials are not timely controlled in construction time, which affects the smooth operation of the road. Cement concrete pouring materials take a long time to dry and solidify ...
