This document discusses techniques for rehabilitating and maintaining asphalt overlays on concrete pavements, including crack and seat, break and seat, rubblization, and saw and seal. Crack and seat and break and seat involve fracturing concrete slabs to shorten their length and allow for interlocking of pieces. Rubblization involves fracturing concrete into pieces smaller than 9 inches to prevent reflection cracking in overlays. Saw and sealing joints is used to control the rate of deterioration of reflection cracks.
