建築一條路所需的臨時東西有什麼??

Temporary Traffic Arrangement (TTA), e.g. road block, temporary traffic sign, temporary road marking.

點樣分析d泥質,之後再決定用咩材料起條路..
Normally, either soft (granular material) or hard (rock)
For soft founding material, we would use flexible pavement with friction course, wearing course, and base course.
For hard founding material, we would use concrete pavement with sub-base and concrete slab.
