Evaluation of Rehabilitation Techniques for Flexible and Rigid Pavements in211 Nevada. Part 1. Cost-Effective Rehabilitation of Portland Cement Concrete 211 Pavement in Nevada

摘要

The purpose of this study, was to evaluate the feasibility of several211u001erehabilitation strategies for Portland Cement Concrete (PCC) pavement. 211u001eRecommendations were made for future crack and seat, rubblization, and 211u001ereconstruction projects based on a review of specifications from several other 211u001estates, the data gathered during the Interstate 80 project, the experience gained 211u001eduring the construction phase of the project, and review of several overlay 211u001edesign procedures. The results of the study, based on 2 years of field 211u001eperformance, indicate crack and seat, rubblization, and reconstruction techniques 211u001eare all viable options. The economic analysis indicates crack and seat has the 211u001elowest initial cost. However, based on projected future performance, both crack 211u001eand seat and rubblization have approximately the same life-cycle cost over a 35 211u001eyear analysis period. Pavement performance monitoring should continue in order to 211u001eevaluate long term performance and cost-effectiveness of each strategy.
