This paper examines the effects of Date palm oil as a bitumen modifier on the compressive strength of bitumen and hot mixed asphalt (HMA) pavement. Date palm oil contains anti-oxidant isomers that have the potential to enhance the performance and durability of bitumen. The compressive strength test of asphalt pavement mixed with Date palm oil was performed in accordance with British Standards BS 1881: Part 116: 1983. The cube specimens of asphalt pavement were manufactured mixing with 0%, 2.5%, 5%, 7.5%, and 10% of Date palm oil out of total sample mass. The experimental results suggested that Date palm oil as a bitumen modifier reduced the compressive strength of HMA pavement. The findings of this paper urge for further experiments to understand the effects of Date palm oil on the asphalt pavements under long-term traffic load, environment and surface drainage.
