| 摘要： | The feasibility of several rehabilitation strategies for portland cement concrete pavement was evaluated. Recommendations were made for future rubblization, crack and seat, and reconstruction projects based on a review of specifications from several other states, the data gathered during the I-80 project, the experience gained during the construction phase of the project, and review of several overlay design procedures. The results of the study, based on 4 years of field performance, indicate rubblization, crack and seat, and reconstruction techniques all are viable options. The economic analysis indicates crack and seat has the lowest initial cost. However, on the basis of projected future performance, both rubblization and crack and seat have approximately the same life-cycle cost over a 35-year analysis period. Pavement performance monitoring is continuing in order to evaluate long-term performance and cost-effectiveness of each strategy. |
