Development of Cost Effective Treatment Performance and Treatment Selection Models, Tech Summary.

摘要

Louisiana Department of Transportation and Development (DOTD) has spent substantial fi nancial resources on various rehabilitation and maintenance treatments to minimize the pavement distresses and improve the pavement life. Unfortunately, a full-scale performance assessment and cost-eff ectiveness analysis of various pavement treatments has not been conducted. A recent study completed by LTRC regarding the pavement management system (PMS) and performance modeling emphasized the importance of developing treatment performance and selection models. In this regard, LTRC initiated a three-phase research study that addresses such needs by developing rigorous treatment performance and selection models that are specifi c to the mission and management strategies of DOTD. The three phases are: Phase I—Review and Project Selection; Phase II—Performance Modeling and Costs and Benefi ts of Treatments; and Phase III—Model Integration and Training.
