Cold-Recycling Techniques Using Bitumen Stabilization: Where Is This Technology Going?

The debate around the implementation of cold recycling methods for road rehabilitation would be purely academic if it weren't for the wherewithal to efficiently perform the task. Creative machine designers with technological foresight have made the debate a real one. The development of recycling equipment has preceded the initiatives of Civil Engineering practitioners to recycle existing pavement materials effectively. Modern recyclers offer minimal energy consumption and wastage with optimal enhancement to performance properties of the mix. The development of accurate mix design and pavement design procedures for told recycled materials by researchers and practitioners has followed the availability of recycling tools. Figure 1 bears testimony to the trend of investment of contractors globally in one brand of cold recycler capable of cementitious, emulsion or foamed bitumen stabilization.
