REMOVING OF PETRO-SET BY FLAME TREATMENT

An attempt is described to oxidize the pavement surface (after application of Petro-Set AT Geotechnic Emulsion) with a flame treatment to reduce its slippery condition. The treatment consisted & about 10 passes by a moderately hot flame. Of thirteen 1-mile sections treated with Petro-Set, 6 sections were flame treated and 1 section was used as a control. Skid tests were made on the 7 sections to evaluate effectiveness of the treatment. The results (tabulated) show that skid resistance has not been improved by the flame treatment process; a majority of sections indicate a reduction in skid number. This section of the highway will, however, be monitored by skid testing to further evaluate the problem.
