Mechanical alteration of the texture of old concrete pavement with the Klarcrete machine. Paper presented at the 53rd Annual Meeting of the Highway Research Board HRB, Washington, D.C., January 1974.

Experiments were performed with the British Klarcrete machine to determine its capability for removing the top layer of roadway to a depth of 1/8 to 1/4 in. and, in so doing, to expose a fresh surface of highly fractured coarse aggregate to give a better skid resistance. The equipment is described and the results are presented.
