In COWI we see the objective of pavement maintenance as that of preserving the structural and functional condition at an acceptable level by carrying out routine and periodic maintenance as long as these activities are economically feasible. At the expiration of such a period, the pavement maintenance activities include the determination of the most cost-effective restoration of the pavement condition, given economic constraints and future traffic.
COWI utilises traditional and state-of-the-art methods from the Benkelman Beam to FWD, laser technology and georadar for condition measurements. Analyses are performed by means of standard software such as ELMOD, PCASE, or in-house developed software.
COWI uses dedicated standard data base systems, such as e.g. the PAVER system for organizing data. Maintenance alternatives are determined in consideration of available materials and technology and evaluated for efficiency and economy according to recognized standards, such as World Bank compliant methods. The use of standardized software facilitates transfer to the client after completion of a project.
