Investigation of the immersion resistance of the HRS-WC mixtures with applying static loading

Abstract

Abstract The inclusion of rainwater often compounds the damage to the road before reaching the plan life through the surface and shoulders of roads. This can lead to the release of aggregates and exfoliation of asphalt on the surface layer. The study aims to determine the level of road durability against the Marshall, volumetric, and durability properties of the HRS-WC mixture. The study used various static loading 100 Kpa, 150 Kpa, and 200 Kpa with immersion. In the immersion method, there are two differences, namely, immersion with and immersion without loading. The test objects’ loading using a simple and economical test tool utilizes the beams and iron cylinders obtained from the laboratory, testing using Marshall Test. The results of the analysis obtained the durability of unloading soaked value higher than the load. The analysis results showed that the durability of the mixture was soaked seven days with a load of 100 KPa was 77.40%, for 150 Kpa amounted to 52.02%, and for 200 KPa, which is 47.67%. Analysis results showed a 7-day immersion value with a cumulative load of 68.38%, while analysis results showed a seven day immersion value with periodic loading of 75.43%.
