Regarding the cracks problem of thermoplastic road marking paint-----2

     Reflection cracks resulting from the cracks in the roadbed. Cracks caused by the expansion or contraction of the roadbed materials, or cracks due to uneven subsidence, etc., can lead to cracks in the road markings. Generally, they cannot be avoided and the construction quality of the roadbed can be enhanced.

     The cracks caused by the softening of the road surface occur in some areas where the temperature exceeds 40℃ in summer. Under the scorching sun, the asphalt surface can reach temperatures above 60℃. The asphalt becomes soft while the coating remains relatively hard. Under the impact load of vehicle wheels, soft cracks in the road surface may occur. The direct cause of these soft road surface cracks is the mismatch in the hardness of the coating and the road surface. They are generated under the action of impact loads and can be alleviated by appropriately adjusting the formula.
