The bituminous section has been engaged in testing silica sand-asphalt mixtures composed of various penetration grades of asphalt and sands from sand and sandstone deposits from several different areas of the state since early this year. The purpose of this study was to develop a surfacing mixture which would provide a skid-resistant surface and which could be machine laid in thin courses.
