Abstract: Putting the road unit reliability to the road network system, using comprehensive topological index of the road network to determine the importance of each road unit and then to determine the road reliability after repaired, finally it can get the thickness of asphalt overlay by the direct integral method. The example showed that when the thickness of asphalt overlay is less than 35 cm, the road reliability with thickness of asphalt overlay increases and when thickness of asphalt overlay gets to 35 cm, reliability with thickness of asphalt overlay tends to a stable value. Considering the position of each road unit in the road  network can not only make maintained road system reliability maximize, but also make optimal allocation of repair costs.

Key words: asphalt overlay, reliability, road network system, direct integral method
