Problems and solutions of road marking--6

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.

Wear resistance problem
1. Road marking wear and traffic volume is directly related to the size. Traffic is heavy, large vehicles are more frequent lane changing sections, the general wear and tear on the fast road marking. In addition, the roads are sand and gravel over the dirt there, it will speed up the marking of the wear and tear. Marking wear resistance and paint itself, is the regulation of production formula, adding some wear fillers such as quartz sand.
2. To ensure a longer life of hot melt marking , we must choose according to different climatic conditions, paint formulations, buy quality and reliable performance and stable raw material. In the melting process in the strict control of temperature, stirring evenly, in the construction process, master the marking of construction speed, to ensure the uniformity of thickness to keep the road clean.

S-line deformation and tooth edge
1. Is mainly tire indentation and scar. Should choose a suitable viscosity and good fluidity of high-quality paint. Strengthen the construction management, coating completely dry open traffic.
2. Coating the surface of vertical stripes, due to hot-melt coating in the heat generated in the process of local burning may also be mixed with a foreign body. In addition, the paint bucket or paint defects notch cinder attachment, it will also result in vertical stripes. Surface in poor condition will directly affect the quality of marking the appearance affect the reflective effect at night. This first paint should she surface with a lateral stripe is due to paint bucket slot vibration, coating viscosity is too large road causes of inequality.
3. Should master the construction of temperature, hopper tank scraper timely inspection and processing. Thoroughly cleaning the road, the construction carts should avoid fighting tank shock.tart heating and melting, strict temperature control, does not allow for burning, and foreign matter mixed. The pre-construction deal with slot machines and the Big Dipper to conduct a thorough inspection and cleaning, so that in a normal state.
