After the road construction, there are times when it is next, but why do you not pave properly?

The next step as shown in the photo is the temporary pavement (temporary restoration) performed on the excavated road, and since all construction has not been completed, final pavement (main restoration) cannot be performed.
Temporary pavement (temporary restoration) is performed in various cases.
In Yokohama City, construction (new construction, repair, etc.) of water, sewerage, gas, etc. buried in roads in public utilities will be coordinated with business operators to prevent unnecessary excavation and shorten the construction period. At this time, temporary pavement (temporary restoration) will be carried out so that the next company can be constructed immediately after the construction of one company is completed.
Even in the case of construction by a single company, for example, in the case of nighttime construction where the construction period takes several days, temporary pavement (temporary restoration) is performed after the completion of daily construction to ensure daytime traffic.
In this way, temporary pavement (temporary restoration) is performed in various cases, and the final pavement (main restoration) is performed after all construction is completed.
In addition, at the time of temporary pavement, the mark of each company is painted on the road surface as follows so that it can be seen that it is a temporary restoration.
