Abstract
The indented type and hooked type steel fibers were selected for roller compacted concrete for pavements. The appropriate unit water content, sand percentage, reinforcement amount were found out, and water reduction degree by incorporating superplasticizer and its appropriate adding percentage by cement content were chosen for a given consistency which was evaluated by the vibrating compaction value measured by a Swedish-type Vebe apparatus. The segregation degree was reduced by using steel fiber, and the fiber angle in the concrete tended to approach the horizontal angle by compaction used surface vibrator. The flexural strength, ductility and frost resistance were improved, and bond strength between the concrete and abraised asphalt pavement surface was evaluated at the age of 7 days. The drying shrinkage was almost the same as the non-fiber roller compacted concrete regardless of increase in the unit water content for a given consistency.
