| Abstract: | In the paper,several methods for evaluating the cavity beneath old pavement slabs with FWD,were summarized and the respective advantages and disadvantages were analyzed.Based on these methods,the evaluation principles were improved and a new type of evaluation method,fuzzy evaluation was introduced on the basis of fuzzy logic.The establishment method and procedure of fuzzy evaluation model were discussed in detail.Based on the old pavement overhaul engineering of Kaiping section,Guangdong Province in G325 National Highway,the application of fuzzy evaluation of the cavity beneath old pavement slabs was carried out with FWD test data on the spot.The practice indicates that the fuzzy evaluation model is effective for pavement overhaul. |
