PennDOT credits its LCCA program with benefits to the department in several areas:
|PennDOT engineers have become more knowledgeable about the costs and performance of various pavement materials and activities. The LCCA process provides opportunities to investigate aspects of pavement life beyond initial construction design.|
Pavement Design. PennDOT has found that pavements designed since the implementation of its LCCA program perform better than pavements designed before implementation. The data requirements of the LCCA process have improved the quality of all pavement design inputs and have led to better pavement designs.
Professional Development. By requiring cost and performance inputs for initial and rehabilitation construction activities as well as for multiple types of materials, LCCA provides pavement design engineers with the opportunity to investigate aspects beyond initial construction design. PennDOT engineers have become more knowledgeable about the costs and performance of different pavement materials and activities, and they are better able to design and estimate to a project's requirements. Additionally, designers are better informed about pavement rehabilitation and preventive maintenance practices than engineers who design without explicit regard for a pavement's future requirements.
Competition. By standardizing its pavement design selection process with LCCA, PennDOT established clear benchmarks for pavement performance. The asphalt and concrete industries have met the challenge imposed by PennDOT and have adapted with better and lower cost products. Additionally, contractors have lowered their bid prices in order to remain competitive in a standardized environment.
Credibility. PennDOT's well-documented, centrally regulated LCCA process improves the transparency of the pavement-type selection process and makes pavement selection decisions less likely to be contested by pavement industry groups.
User Costs. With the capacity on many roadways already taxed, PennDOT has formally recognized that work zone activities cause roadway users delay and additional vehicle operating costs. PennDOT uses LCCA as a framework for considering tradeoffs between user costs and agency expenses at the project level.
