Study on Water Stability of Warm Mix Drainage Asphalt with Sasobit

Abstract:

To study water stability of Sasobit warm mix drainage asphalt (WMDA) and improve it, OGFC-13 WMA is primarily prepared with polyester fibre and Sasobit. According to the test results of specimens, formed at 5 different compaction temperatures by marshall tests, the optimal compaction temperature is determined. Then, general water stability tests were used to test the water stability performance of 4 kinds of asphalt mixtures, which were porous asphalt mixture of hot mix (OGFC-1),Sasobit WMDA without any anti-stripping agents (OGFC-2), Sasobit WMDA added hydrate lime (OGFC-3) and Sasobit WMDA added hydrated lime with quick lime (OGFC-4).Test results show that optimal compaction temperature is 150°C; water stability order (OGFC-3>OGFC-1>OGFC-2>OGFC-4) shows that using hydrated lime has beneficial yet limited effects to it. Hydrated lime with quick lime should be avoided for its adverse effect.1.5% hydrated lime shows best water stability.
