Tensile Strength Improvement Using Fibre Reinforced Crushed Rock

Abstract

This study aims to report the possible use of fibre to improve tensile strength of crushed rock base in pavement in order to reduce cracking of cemented material. As is well known, stabilized materials always present brittle response under applied load and are unable to sustain suddenly collapse after peak load. From this point, it means that cemented material only advances compressive behaviour but it will never enhance long term performances such as fatigue and durability. Cement treated crushed rock with fibre was selected to represent tensile strength of pavement base material. Sophisticated tests were conducted to observe mechanical responses under applied load such as indirect tensile and unconfined compressive strength, resilient modulus. Test results showed that fibre reinforcement would be improved tensile strength and ductility of stabilized material.
