In situ cold recycling

In situ cold recycling is an effective process for the rehabilitation of existing deteriorated pavements, where failures are limited to the upper pavement structure. It is applicable to both 100 per cent asphalt recycling and to asphalt or sealed pavements with the incorporation of base course materials. Highly productive mobile equipment enables the process to be carried out efficiently, with minimum disruption to traffic and the whole roadway is open to traffic after work each day. The process is 'environmentally friendly', cost effective and energy efficient, using only a minimal quantity of new materials. The re-use of existing materials, its structural capabilities and resistance to cracking make the ISCR process viable for many types of pavement distress. The process has been successfully used overseas for many years on low, medium and heavily trafficked pavements and in the USA is a recognised rehabilitation practice. In-situ cold recycling will assist road engineers in improving the level of service of old pavements to carry traffic into the 21st century.
