Regarding the cracks problem of thermoplastic road marking paint-----1

      During winter construction, the coating contracts when exposed to cold, generating internal stress. When this stress accumulates in one area, it is highly likely to cause cracks. Cracks caused by cold are related to the construction season and the performance of the coating, as well as the condition of the road surface. Especially for newly laid cement roads, there is a fragile mortar layer or curing film, which makes them prone to cracking. To prevent cracks caused by cold, the first step is to choose an appropriate construction season and avoid conducting line marking work in the cold winter. At the same time, it is important to use thermoplastic paint reasonably and select the appropriate coating ratio for each season. For newly laid cement roads, the curing time should be more than 2 weeks, and the fragile mortar layer or curing film on the road surface should be cleaned before the road marking work.
