| 摘要： | The purpose of this study, was to evaluate the feasibility of several rehabilitation strategies for Portland Cement Concrete (PCC) pavement Recommendations were made for future crack and seat rubbilzation, and reconstruction projects based on a review of specifications from several other states, the data gathered during the Interstate 80 project the experience gained during the construction phase of the project and review of several overlay design procedures. The results of study, based on 2 years of field performance, indicate crack and seat rubbilzation, and reconstruction techniques are all viable options. The economic analysis indicates crack and seat has the lowest initial cost However, based on projected future performance, both crack and seat and rubbilzation have approximately the same life-cycle cost over a 35 year analysis period. Pavement performance monitoring should continue in order to evaluate long term performance and cost-effectivertess of each strategy. |
