If the quantity of marking work is not large, such as redrawing the old line in some sections, the hot-melt road marking machine can be used for ordinary pushing or holding test. Because the small hot road marking machine is small in size, flexible in construction and convenient in transportation, the construction team can take it to the construction section quickly to complete the construction. The experienced construction team knows that the quality of marking is closely related to many factors, such as road environment, road marking paint quality, road quality, air humidity and temperature during construction, etc. The road marking machine, although one of the important factors affecting the quality of marking, is not a decisive factor. The quality of the road marking machine determines the efficiency of the marking construction. The role of the road marking machine is to save users’ time and labor costs. Big driving type road marking machine can construct an average of 10 kilometers per hour, while a manual road marking machine can only work for 8 hours a day to construct 5-6 kilometers. Take a 100km highway for example. It will take a day to work overtime with a driving type road marking machine. Of course, under ideal conditions, the actual construction may take more time, so we can calculate it as 3 days longer; However, the traditional hand propelled road marking machine wants to complete the 100km marking project in three days, even if five hand propelled road marking machines are used together to work overtime at full power. Moreover, if it rains during the construction of the road marking machine, the construction period will be extended indefinitely as long as the rain continues. Especially in the rainy season in the south, this kind of situation is particularly frequent. The Driving type marking machine can catch the rare good weather in this season and complete the construction in a short time. As long as the marking construction is completed when the pavement is dry, the impact of rainstorm on the marking quality is minimal. As the domestic labor cost becomes higher and higher, the advantages of the Driving type road marking machine will become more and more obvious. Using it to mark lines every day is equivalent to saving 5-6 workers for three days.
