Challenges and solutions to the impact of cooling on road marking

Challenges and solutions to road marking caused by cooling

Under low temperatures, road marking paint may produce internal stress due to rapid shrinkage. When this stress is concentrated in one place, it is very easy to crack. This crack caused by cold weather is not only related to the construction season and the performance of hot-melt road marking paint, but also to the road conditions. In particular, newly laid cement roads are more prone to cracks due to the presence of fragile mortar layers or maintenance films.

When hot-melt road marking is carried out at low temperatures, hot-melt paint that adapts to the climate must be selected, the construction temperature must be strictly controlled, appropriate glass beads must be selected, and effective measures must be taken. At the same time, attention should also be paid to issues such as construction safety and environmental protection. Only in this way can the smooth progress of hot-melt road marking construction be ensured and quality requirements can be met.
