CANPav™ 2.0 online version. This application is designed to allow users to easily compare the life cycle cost and performance of equivalent concrete and asphalt municipal pavement cross-sections. CANPav™ 2.0 is unique in that it allows users to easily compare options, utilizing the data for twenty-four default municipal concrete pavement cross-sections with the equivalent asphalt cross-sections. Users have complete control and can change any cross-section or material cost inputs that will be used to construct estimates for municipal streets or commercial parking lots. The software also has a built-in Maintenance and Rehabilitation schedule for both concrete and asphalt pavements to estimate the life cycle cost of a project over a 50 year analysis period.

Users may access the program at www.canpav.com.  Once logged in, they can quickly conduct numerous “what if” scenarios comparing the initial construction costs of both concrete and asphalt paving materials and save on their projects.
