Overview
Full depth repair (FDR) is a concrete pavement restoration technique that restores isolated slab structural integrity and rideability and deters further deterioration, thus extending the pavement’s service life. FDR is suitable for a wide variety of distresses that are beyond partial-depth repair, such as transverse & longitudinal cracks, corner breaks, deteriorated joints, D-Cracking, blowups, and punch-outs. FDR involves making lane-width, full-depth saw cuts to remove the deteriorated concrete down to the base; repairing the disturbed base; installing load-transfer devices; and refilling the excavated area with new concrete. The cost of FDR is largely dependent upon the size, number, and location of repair areas, as well as the type of concrete mix used.
This course is intended for civil engineers who are interested in restoration methods for pavements, particularly Portland cement concrete (PCC).
To earn credit for this course, you must pass a multiple choice quiz consisting of fifteen (15) questions.
