Abstract

Fatigue and tensile is a performance indicator for road pavement. A bituminous mixture that good in durability, strength and performance will give a long life span and low cost maintenances of the flexible pavement. For this project, it was deals with two types of bitumen which are 60/70 penetration grade and 80/100 penetration grade. The bituminous mixture design use is Marshall Mix design to perform Asphaltic Concrete and Hot Rolled Asphalt type of mixtures. The test was conducted in order to achieve the objective is Beam Fatigue test and Indirect Tensile Stiffness Modulus. From the result, it is shown that 60/70 pen grade bitumen indicates higher value in initial stiffness, modulus of elasticity and maximum tensile stress compare to 80/100 pen grade bitumen. However, bitumen 80/100 penetration grade demonstrate higher number of cycles compare to 60/70 penetration bitumen. Although the bitumen content for HRA mixture more higher from AC mixture, the stiffness of mortar give more influence in term of performance compare with the interlocking effect of aggregate. In term of construction, the HRA mixture would be more costly due to high bitumen content needed to be use but the maintenance may be lesser compare to AC mixture.
