| Summary: | (ESAL). A research database was created by extracting 19, followed by twenty-year projected axle repetition 19), shallow rutting, deep rutting, and alligator all the evaluated performance models. analyses, statistical hypotheses tests, percent and which needed to be modified. The performance at a time approach was used. The F-statistics calculated using MODULUS software. The selected considered in the evaluation. A sensitivity analysis corresponding to the relevant input variables were could not be checked. It was observed that none of the cracking, which are the fundamental performance data from the Long Term Pavement Performance (LTPP) database for pavement sections in Texas. A11 data difference, and estimated reliability. Due to the lack evaluation. From the family of flexible pavements, the integrating pavement management systems at the two items except rutting data were extracted using the levels. The objective of the study is to identify measures of the flexible pavements, were selected for models for ride quality (serviceability index for FPS- moduli of pavement layers and subgrades were back- newly constructed pavements with untreated base were number of problems to a manageable size, a one factor of data, all members of the performance model families others. Therefore, improvements are recommended for part of the study to develop an approach for pavement management at network and project level performance models were evaluated using trend predicting the values observed at the LTPP sites reliability level is the most important factor in FPS- respectively, generally do not give the same answer sections were available for the evaluation. Elastic selected performance models of PMIS and FPS-I9 is software, Database 97. Rutting data was obtained from the flexible pavement design software, FPS-19, used by the input variables to FPS-I9 program. To reduce the the LTPP regional office. Data from sixteen pavement The pavement management information system (PMIS) and hics. the Texas Department of Transportation (TxDOT) for though some of them are predicting better than used to determine the ranks. It was found that was performed to determine the relative importance of when the same set of data are used. This thesis is a which performance models were working satisfactorily |
