AN APPROACH TO COLD RECYCLING OF BITUMEN AND

Driven by a desire to make more prudent use of natural resources, the recycling of existing pavement materials has become a viable option for maintaining roads. The concept of using cold recycling has evolved over many years and is now a recognised form of road construction. Following the introduction of a design guide in 2004 (D Merrill et al, 2004), both in situ and ex situ recycling techniques have been used to reconstruct and maintain roads. Advantages of cold recycling over traditional construction methods include reduced amounts of energy, fuel and material consumption. Currently pavement designs in the UK (CD 226) are permitted to contain cold recycled
