PENNSYLVANIA REPORTS ON EXPERIMENTS WITH GUSSASPHALT
The article describes results given in an interim report on an experimental project using the cast-in-place mastic asphalt. Several problems were encountered in the laying of the mastic asphalt. It was found difficult to correct surface irregularities due to its rapid setting and entrapped air caused bubbles to be formed on the surface shortly after screeding. Periodic skid resistance and road roughness measurements showed that the nearby control sections of id-2a gravel asphalt gave slightly better values. The mastic asphalt was estimated to have half the wear of the id-2a, but cost three times as much to lay. Recommendations are made to improve the mixing and placing characteristics of gussasphalt. It was thought that with more experience a good surface finish with adequate skid resistance could be obtained with the mastic material. /TRRL/
