As CDOT continues to seek progressive ways to provide the most effective multi-modal transportation system for its customers, the agency will increase its emphasis on probabilistic inputs in its LCCA process.
CDOT will incorporate the Mechanistic Empirical Pavement Design Guide (MEPDG) into design practices as soon as it is validated and calibrated to Colorado's site conditions, materials, and typical design features.(12) The agency will continue partnering with FHWA to further improve RealCost software as well. In addition, CDOT hopes to enlist an independent review of its LCCA processes that will identify specific cost savings and opportunities for quality improvement.
CDOT's pavement design and management team will continue to lead the agency in LCCA. The team believes that effective LCCA, when viewed as an investment strategy, will allow the entire organization to make the best, long-range, long-term decisions for the State, especially as it navigates through challenging economic times.
