From engineering analysis viewpoint, it is desirable to control pavement cracking to joint locations at desirable intervals to decrease the possibility of uncontrolled cracking. An approach for estimating appropriate sawcut depths and placement timing by using fracture mechanics for jointed concrete is suggested. Early-age sawcutting has been applied to concrete pavement surfaces at specific contraction joint locations. Preliminary fields results show that early-age sawcutting with appropriately determined jointspacing and depth can be used for both positive control of cracking in jointed plain concrete pavements. Recent pavement surveys have verified this results.
