The Tensile Properties Of A Polymer Fibre Reinforced Hot-rolled Asphalt Mixtures
The tensile properties of bituminous mixtures are of interest to pavement engineers because of the problems associated with cracking. The resistance of bituminous mixtures to cracking is dependent upon its tensile properties, notably its tensile strength and extensibility characteristics. Fatigue or cracking in pavements has been defined in the literature as the phenomenon of fracture under repeated or fluctuating stresses having a maximum value generally less than the tensile strength of the material. This study involves a laboratory investigation on the tensile properties of a Hot-Rolled Asphalt (HRA) bituminous mixture reinforced with synthetic fibres. Two types of fibres were used namely polyester and polypropylene. The Indirect Tensile test was employed in determining the tensile properties of these bituminous mixtures.
