ABSTRACT
It has recently been established that steel fibre reinforced concrete matrices (1,2) offer the possibility of reduced pavement thickness or higher load carrying capacity, reduced deflections and crack widths. The composite matrix, exhibits a substantially higher flexural strength. At design loads normally encountered in highway pavements, the stresses induced in the SFRC pavements are much lower than the flexural strength of the matrix. At higher loads, SFRC pavements are capable of bearing stresses much beyond the flexural strength of the matrix. Under the present investigation, the performance of SFRC pavements containing fibre volume between 0.5–2% has been evaluated under static plate load tests. SFRC pavements having a nominal thickness of 100 mm used in the investigation have shown a remarkable improvement in the load carrying capacity.
