【 摘 要 】

In this paper, the effects of steel fibre usage on concrete pavement thickness and cost were investigated. Prepared fibrous concrete specimens were subjected to physical and mechanical tests. From the experiments, it was determined that as the steel fibre ratio increased, the workability and compressive strength of the specimens decreased, but the flexural and splitting tensile strengths increased. In addition, according to calculations made using the AASHTO 1993 design method, the concrete pavement thickness decreased in the range of 4.35 to 18.66 % with an increase in steel fibre, but the pavement cost increased by 56.50 to 74.07 %.
