This report provides information on life cycle cost analysis (LCCA) as applied to CDOT's roadways. It describes the methodology CDOT uses to select discount rates to be used in LCCA calculations. It also summarizes pavement selection terminology for deterministic and probabilistic LCCA procedures.
Describes the development and application of geographic information systems (GIS) and remote sensing (RS) databases and analysis models for cumulative effects assessment resulting from growth associated with transportation infrastructure.
This study evaluates the strength and long-term performance of CFRP prestressed panels in a bridge deck, compare the behavior of bridge decks designed with the empirical and conventional methods of AASHTO, and a new limit-state design, and examinne the influence of lap splices between precast panels on deck cracking.
The Colorado Department of Transportation (CDOT) is currently investigating approaches to reduce the frequency and severity of work-related injuries. The incident rates for CDOT are significantly higher than those achieved by some private organizations and comparable DOTs.
