Rectify bleeding road surfaces using hot in-place recycling method: how it should be done (Malaysia experience)

Hot in-place recycling (HIPR) is a pavement rehabilitation method which is relatively new in Malaysia. Since its inception in the early 1990‟s, the process of heating up and loosening the existing bituminous surface, followed by mixing with or without a small quantity of rejuvenating agent prior to laying back at the same location in a single pass operation has been proven in reshaping uneven surface and "removing‟ shallow surface cracks, minor rutting, as well as raveling and stripping. However, treating the bleeding surface using this technique without adding new materials is indeed a daunting task. The challenges that arise in rectifying this type of surface defect include making sure that the excess binder content is no longer detrimental to the surfacing material, and compaction of the recycled material containing the age-hardened binder is adequate without creating too large air voids that would consequently affect the durability in the future. This paper highlights the treatment done on the severely bleeding surface of the newly completed Lebuh AMJ in Melaka using the HIPR technique.
