Evaluation of Skid Resistance for High-Type Bituminous Surfaces
Investigations of 13 field test sections indicated that the key to preventing early loss in skid resistance is to ensure that field air-void contents do not fall below 3.4 percent for ID-2 mixtures and 3.0 percent for ID-3 mixtures. A new procedure was developed and recommended to determine optimum asphalt content and to screen mixture designs that are particularly sensitive to changes in asphalt content. The modified Texas gyratory compactor, using the new SHRP protocol, was found to do a better job than Marshall compaction in the production of laboratory mixtures that are more representative of the field.
