Full depth reclamation with Stabicol binder in Thailand: a case study

Stabicol is a combination of two well-known binders that were previously incompatible: bitumen and cement. It combines advantages of both binders: strength of cement and flexibility of bitumen. It forms a stiff yet flexible base course and eliminates the risk of cracking while giving road pavements a high degree of mechanical performance. It is used in new road construction as well as in reinforcement and rehabilitation of existing roads through in place recycling. The binder is composed of cement, water and a bitumen emulsion specially designed to provide high stability with cement, good coating and long workability in place. Components are blended into a special slurry unit set up on the machine itself. Dosages are controlled by flowmeters and monitored by computers. Stabicol is introduced through a spray bar. The traffic is re-opened immediately after compaction and leveling. The surface is protected with a tack coat and the structure is completed with a 5cm wearing course. Thanks to its good workability and fast hardening, control tests on in situ samples and core drills exhibited exceptional performance above the specifications.
