Overview
Design of concrete pavements has remained the same for decades, however with the traffic and axle loads on pavements have continued to multiply. In concrete pavement, critical stresses are developed due to the combined effect of flexural stresses due to wheel load and positive temperature differential leading to initiation of cracks.
Adding fibers to concrete improves flexural fatigue strength, toughness, impact strength and load carrying capacity. Designer engineers in Pakistan started use of fiber reinforced concrete (FRC) on large projects from 2005 including Lucky Cement at Nooriabad.
Based on the success at Lucky Cement, consultants have started specifying FRC to make the pavement more durable and resistant to cracking. FRC replaces temperature distribution steel in pavement resulting in major cost saving.
