EXPERIENCE IN THE UK OF RECYCLING WITH CEMENT FOR THE STRUCTURAL MAINTENANCE OF PAVEMENTS

Recycling of existing pavement materials has become an increasingly important feature of the maintenance of highways in the UK in order to address environmental concerns and reduce construction costs. As a result of this a major research project in the UK has concentrated on promoting the re-use of materials and in particular cold in situ recycling techniques. The 'Linear Quarry Project' aimed to promote cold-in situ recycling by providing evidence of acceptable in-service performance and to provide guidance on structural design and specification. The project built on previous experience and resulted in an extension to the design life of cold-in situ recycled roads, thus making this structural maintenance technique more economically competitive. The project was jointly funded by clients and industry, primarily the Highways Agency, and the research results have led to the increased use of this technique in the UK. This paper provides details of the full-scale trial of deep cement-bound cold-in situ recycled materials. Risk assessment recommendations are outlined from the results of the trial. The objectives of the new SMART research project 'Sustainable MAintenance for Road Treatment' are also summarised. SMART aims to deliver a less prescriptive and a more versatile performance based specification for a wider range of recycling applications. For the covering abstract see ITRD E125033.
