The Effect of Using Activated Date Seeds on Hot Mix Asphalt Performance
04 March 2021
ADU Professor Mohammad Alkhedher, with colleagues from Kuwait University and Jordan University of Science and Technology, recently published a paper in a leading peer-reviewed journal investigating the performance of date seeds as an alternative aggregate in asphalt concrete mixes. They examine three activated date seed additives, as a partial replacement for fine aggregates, in hot mix asphalt. They report from comprehensive strength and Marshall Stability Tests (MST) that a 10% ratio provided the highest result from the MST, while a 7% ratio had the highest strength index.
Professor Mohammad Alkhedher said: “Sustainability of the built environment is an important issue globally which is reflected in the United Nations sustainable development goal 11: sustainable cities and communities. The findings in this paper are important as they show how we can use readily available sustainable natural material to produce high performance hot mix asphalt”.
