Certain highway locations need exceptionally high skid resistance because of the alignment, geometry, and drainage of the roadway and the complex turning maneuvers required. Several beam specimens made of bituminous mixes incorporating unconventional aggregates with physical characteristics likely to produce high skid resistance were installed in a pavement and tested periodically for skid resistance. The skid resistance values of the experimental mixes and a conventional resurfacing mix were approximately equal after 700,000 accumulated vehicle passes; therefore, there was no apparent benefit from using the unconventional aggregates.
Virginia has provided skid resistant pavements in the limestone area of the state by placing thin overlays of sand mixes incorporating local materials...
This report describes the skid performance after four years traffic of several experimental sections containing from 0% to 36% nonpolishing aggregate ...
