APPRAISAL OF ALTERNATIVE METHODS FOR RESTORATION OF PAVEMENT SURFACE TEXTURE
This report covers the methods that have been used to provide surface texture for worn pavements in California. Worn grooved PCC pavements appear to have the greatest need for new methods since longitudinal grooving continues as a cost effective treatment for worn PCC pavements. For economic reasons, regrooving in the wheel paths of worn grooved pavements should be tried. If regrooving is unacceptable, it appears that diamond blade grinding is an effective texture treatment in addition to providing a desirable plane for any subsequent grooving. Open graded asphalt concrete overlays on PCC pavements have been used successfully on lightly traveled roads and are now being evaluated on roads with heavy traffic. Cold planing PCC pavements is not acceptable in California because of the excessive spalling at cracks, but it may be an acceptable treatment for AC pavements. Continued evaluations of all methods are necessary because it may take ten or more years to determine the effectiveness of a surface treatment. (FHWA)
