Abstract

The invention belongs to the technical field of road sealants and in particular relates to a road sealant for use at a normal temperature and a preparation method thereof. The road sealant is prepared from the following raw materials in parts by weight: 45-65 parts of pitch, 2-6 parts of resin, 0.5-1.5 parts of emulsifier, 0.3-0.6 part of stabilizer, 10-20 parts of modifier and 35-45 parts of water. The road sealant can be used at the normal temperature, and is capable of treating pavement frost boiling distress caused by reflection cracks for pressure crack pouring of the underneath layer and the base layer of the pavement.

Description

technical field [0001] The invention belongs to the technical field of road sealants, and in particular relates to a road sealant used at normal temperature and a preparation method thereof. Background technique [0002] The traditional filling and sealing of pavement cracks is to heat and melt the hot-melt sealant and pour it into the cracks. Traditional hot-melt sealant grouting is only suitable for fine cracks on the surface of the pavement caused by the shrinkage of the surface material and periodic changes in temperature, but it is no longer suitable for the reflective cracks on the pavement caused by the base layer or roadbed. Hot-melt sealant for slotting and joint filling sealant can only penetrate 3-5mm into the road surface, and cannot fill the cracks below 5mm on the road surface. Mud everywhere. In the treatment of road surface network cracks and reflection cracks caused by cracks in the base layer and other diseases, hot-melt sealants cannot be treated. Cont...
