Problems solved by technology

[0003] At present, concrete and asphalt are the most commonly used road repair materials. Concrete structures have good mechanical properties and durability. However, due to the limitation of particle size and fluidity, concrete is generally only suitable for grouting cracks with a wide width (greater than 3mm). In addition, concrete is inconvenient or impossible to construct under rainy weather conditions. After construction, it needs a certain period of maintenance to achieve good mechanical properties. Roads need to be blocked and cannot be opened to traffic in time. It is opened to traffic quickly, but its mechanical properties are poor and its compressive strength is very low. In addition, modified asphalt needs to be boiled or mixed on site, which not only pollutes the environment but also takes a long time to construct. Easy to flow and pollute the surrounding roads

Abstract

The invention provides a rapid road patching resin. The resin comprises the following components in parts by weight: 227.95-242.05 parts of diol, 361.81-428.19 parts of anhydride, 281.3-298.7 parts of diluent, 2.34-2.86 parts of dimethylaniline, 0.18-0.22 part of polymerization inhibitor, 0.34-0.42 part of paraffins and 0.12-0.14 part of stabilizing agent. The resin has the following advantages: the resin has good flowability, can voluntarily flow appropriately during construction and is convenient to operate; and the resin has high bonding strength and can reach good mechanical properties, the two-hour compressive strength is not less than 60Mpa, the 24-hour compressive strength is not less than 70Mpa, and the resin is excellent in compressive strength and shock resistance.

Description

technical field [0001] The invention relates to a road repairing resin, in particular to a road quick repairing resin and a construction method of the road quick repairing resin. Background technique [0002] Concrete pavement is one of the main structural forms of highways, bridges, and urban roads. Under traffic loads and natural environmental factors, cracks, potholes, edge collapse, and misplaced platforms often occur on the pavement. In order to ensure road safety It is necessary to repair the damaged road surface in time. [0003] At present, concrete and asphalt are the most commonly used road repair materials. Concrete structures have good mechanical properties and durability. However, due to the limitation of particle size and fluidity, concrete is generally only suitable for grouting cracks with a wide width (greater than 3mm). In addition, concrete is inconvenient or impossible to construct under rainy weather conditions. After construction, it needs a certain pe...
