The experienced construction team knows what kind of marking machine is used for the expressway. The quality of the marking machine is closely related to many factors, such as road environment, marking paint quality, road quality, air humidity and temperature during construction, etc. The marking machine, although one of the important factors affecting the quality of marking, is not a decisive factor. The quality of the marking machine determines the efficiency of the marking construction. The biggest role of the marking machine is to save users' time and labor costs. Because the small hot melt 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. If the work amount is relatively large and the traffic flow in the marking construction section is dense, it is recommended to use efficient vehicle mounted or passenger driven marking machines. Because the marking construction needs to close some construction sections, which will affect the traffic. The faster the marking construction task is completed, the smaller the impact on the traffic.

1. On average, a passenger marking machine can construct 10 kilometers per hour, while a manual marking machine can work 8 hours a day to construct 5-6 kilometers. Take a 100km highway for example. It takes a day to work a little overtime with the driving marker. Of course, this is ideal. The actual construction of the marker may take more time, so we can extend it for three days; However, the traditional hand propelled marking machine wants to complete the 100km marking project in three days, even if five hand propelled marking machines are used together to work overtime at full power.

2. If it rains during the construction period, the construction period will be extended indefinitely as long as the rain does not stop. Especially in the rainy season in the south, this kind of situation is particularly frequent. The riding marking machine can catch the rare good weather in this season and complete the construction in the shortest time. As long as the marking construction is completed when the pavement is dry, the impact of rainstorm on the marking quality is minimal.

3. With the increasing domestic labor costs, the advantages of the riding marker will become more and more obvious. Using it to mark lines every day is equivalent to saving 5-6 workers for three days. In addition to the impact of economic development, most of the differences between the east and the west of our roads are due to the fact that China's terrain is high in the west and low in the east, with many plains in the east and mountains in the west.

4. The selection of the marking machine in the marking machine has little to do with the road grade, but is closely related to the road width, marking quantities, terrain, traffic flow and other factors. If the quantity of marking work is not large, such as redrawing the old line in some sections, the hot-melt marking machine can be used to push or hold the test.
