This project aims to recycle non-biodegradable waste (non-opaque, transparent and colored plastic bottle waste, tire waste) to enable its reuse or application in the production of a less costly and more resistant material for building new tarred roads in Cameroon. For this a hydrocarbon binder will be designed. By doing so, the project also aims to preserve non-renewable resources, especially aggregates (gravel and sand) of which less will be required in this new constitution of tarred roads. The particularity of this project is that it is implemented as part of a doctoral thesis.
