Cement Stabilized Macadam Base In-place Recycling Research In Guangxi Region

In recent years, most of the Guangxi region have entered the medium and large asphalt pavement repair stage, during the excavation of the road, the road is bound to generate a lot of waste pavement material,The old cement stabilized macadam is a high strength and stiffness, antifreeze and water stability are good, but the performance is relatively poor resistance to cracking, how to recycle this material, has become a way of scientific research and engineering staff must be addressed.this paper studies the regeneration of old cement stabilized macadam base cons truction methods including mixing plant regeneration, in situ regenerationutilization and multiple head local crushing recycling, and their applicable scope,construction process and quality control, through investigating the Guangxi region traffic, pave ment material usage, structural forms, sum up the basic structure of the five origi nal asphalt pavement, according to the basic structure of the five kinds of asphalt pavement of semi rigid baseregeneration, reach the different of semi rigid base as phalt pavement regeneration of typical structure that provides certain reference val ue for the construction technology of semi rigid base recycling.
