An Investigation of Cracking of Slag-Aggregate Concrete Pavements.

摘要

The frequency of cracking in some western New York pavements containing blast-furnace slag coarse aggregate and in others containing other coarse aggregates was investigated. Cracking in slag-aggregate pavements was found to be seven times more frequent than in pavements containing other aggregates. No differences were found in riding quality and service life,but slag-aggregate pavements exhibited a higher level of skid resistance.
