Abu Dhabi Municipality (ADM) has announced that it has set a target of 100,000m² of road rehabilitation to be performed through the cold planing recycling method in 2013. 

According to Ramin Yazdani, P.E. of the Internal Roads & Infrastructure Division, ADM: "The specification will be in the contract documents. Contractors will be allowed to propose their approach to rehabilitation."

It follows a pilot programme in the Emirate that found substantial savings, both for energy and costs, through the re-use of the milled material in rehabilitiating roads.

The cold planing method is suitable for maintenance of roads. Both the wearing course and the sub-base of the road surface is milled by a rotating head. The milled material is then mixed with an asphalt cement and re-laid over the milled road, a process that has been in use for around 30 years elsewhere.

Based on the Abu Dhabi trial, the key benefits were found to be a 70% faster construction time than building a new road, a cost reduction of 30%, and an 80% reduction in the use of virgin materials. Additional benefits included less dumped CWD material, and a reduction in the number of heavy vehicles on the road transporting materials.

Qatar has also conducted pilot trials, but is yet to specifiy it for projects.
