New materials for epoxy resin repair cement pavement

The cement pavement maintenance and construction technology using new materials of epoxy resin was successfully achieved in the restoration project of the North Laoyiu Highway in Zaozhuang, Shandong Province. This achievement fills the gaps in new techniques and materials for repairing cracks in the cement pavement of highway road surface construction. The construction pavement repair and maintenance technology.
In the Zaozhuang City, Shandong Province, a total length of 39.4 kilometers of the "three vertical and three horizontal" company's skeleton project from the north stay road to the old road in Tengzhou, China Railway 18th Bureau conducted scientific research. They used epoxy resin to repair new materials, mixed a certain amount of polysulfide rubber in the epoxy resin, and diluted it with acetone to a moderate consistency. The polysulfide rubber itself has good elasticity and adhesion after vulcanization. This new material has the advantages of fast-hardening, early-strength, and strong adhesion. It also reduces the brittleness of polysulfide rubber and improves ductility. At the same time, it also has the advantages of small shrinkage, high wear resistance, good durability, simple construction process, etc. It not only saves the manpower, material resources, and financial resources spent on the removal of strips or strips, but also the color of the pavement after repair and the original pavement. It is basically the same, where the patch is firmly bonded and does not fall off. There is no new penetration crack.
