Problems and solutions of road marking--5

Problems of road marking-Skin Peeling off
On the highway construction, road marking, we often encounter the some kind of problems. I have accumulated some experienceam through learning and practice in the long-term highway construction, the following are several common problems and solutions on the hot-melt marking construction i will share with you.
1. Pavement breaks in the skin from the phenomenon. Adjustable coating formulations to increase the bond strength and flexibility
2. Road sweeper does not clean, not thorough, or not to use the next Paint. The construction procedure should be strictly in accordance with the construction to ensure construction quality
3. Under the Paint coating for a prolonged period without drawing a line (or sandstorm weather, construction) and easy to glue dust, can cause skin marking off date; the next Paint painting immediately after drying marking.
4. S-line coating moisture level of impact by road, the road there is water, or more humid must take measures to dry and after construction. To ensure that road construction should be dry, in exceptional circumstances, must meet deadlines, can be dried by artificial means;
5. Ambient temperature is below 5 ℃, the construction quality and unstable, prone to peeling off, melting temperature is too low, will seriously affect the standard line and the cohesive force of the road; if not handled under the Paint, the environment should the temperature at 10 ℃ the above construction is better. Paint coating to the surface temperature should not be less than the instantaneous 180 ℃; construction should be considered a winter's day from 10 am to 3 pm during the environmental temperature is not too low.
6. Paint melting inadequate mixing inequality. Construction of paint should be fully melted, stir well, and aging full post before being coated;
7. Cement road surface paint by the inappropriate choice of a new road paved with concrete and brittle due to surface layer of large and there is basic, easy-off from skin.
Should use permeable concrete pavement under the Paint treatment can improve adhesion strength. The new poured cement pavement careful cleaning.
