Bituminous binder modification has been acknowledged as one of the methods to improve asphalt pavement quality. This study is focussing on investigating the effect of Portland cement and hydrated lime on asphalt pavement of which different percentages (4%, 6% and 8% by weight of bitumen binder) were added to the control 60/70 pen grade bitumen. The effect of the two additives were evaluated through penetration, softening point and dynamic shear rheometer (DSR) tests. Temperature ranges of 20oC 40oC were used for the DSR rheological testing. The results showed that addition of both hydrated lime and Portland cement had a significant influence on the binder properties. A reduction in penetration and increase in softening point temperature were observed with increase in additive content, this indicates improvement in stiffness and rutting resistance. Also, the DSR rheological analysis shows that the modified binders have higher rutting resistance.
