Road construction is mainly two steps. First, the subgrade is the bearing layer, mostly filled with lime soil, which needs to be compacted to reach the compaction coefficient of the design drawings. Second, after the self-inspection by the construction unit, it will be reported to the supervisor and then to the quality inspection station, so that the people in the designated laboratory can do deflection experiments.

Precautions for road construction safety:

1. Before construction, the underground pipelines should be surveyed and marked to prevent accidents such as water leakage, air leakage, electric leakage and explosion burns.

2. Do a good job in the safety protection of key facilities such as site leveling points and poles.

3. Set up security patrol personnel at the construction intersection to guide vehicles and pedestrians to bypass the safety zone.
