Estimation of Cement Concrete Pavement Slab Void Ratio Based on FAHP Method
Slab void is one of the most serious diseases. Maintenance workers need to repair them in time otherwise the whole slab will be damaged. It is very important to ensure the engineering quantity in maintenance. The pavement diseases analysis model relating to void have been established and the weight are calculated by FAHP. Heavy traffic loads have an effect on void, thus the traffic grade affection coefficient ξ to modify the calculation model has been introduced in order to meet the practice. Damage blocks are multiplied by corresponding weight and traffic grade affection coefficient, and then the void ratio is the sum blocks calculated divided by the whole blocks. The results of test section in Hunan expressway show that void ratio estimation by FAHP is contiguous to that by FWD (Falling Weight Deflectometer). In view of this, the method has good practical significance in void slab treatment plan.
