WebMar 21, 2024 · Samples were prepared at bitumen content 3.5%, 4.0%, 4.5%, 5.0% and 5.5%. Marshall stability test of OGPC samples was carried out in the similar manner as for SDBC and DBC. The results obtained are as: Maximum stability, kg = 671 at bitumen content, % = 4.0. Maximum bulk density, gm/cc = 2.30 at bitumen content, % = 4.0 WebAlternatively, an existing agency-approved mix design can be used. The initial mix design is then tested with the selected rutting and cracking tests at three or more binder contents at intervals of 0.3 to 0.5 percent. A binder content (not necessarily the lowest content) that satisfies both the rutting and cracking criteria is selected as the OBC.
