7. SUSTAINABILITYWorking GroupLeader: Rob Vos<strong>Tour</strong> scopeGroup: David Angell, Trevor Distin, Russell LoweSustainability – recycling, warm mix asphalt, efforts to reduce carbon footprint, carboncalculators and the impacts for road asset managementCold in-plant manufactured Bitumen Stabilised Material using Recycled Asphalt – eThekwini / DurbanFeedback fromKrishna Naidoo,, Dave Collings,Tony Lewis, Saied Solomons, Kim JenkinsObservationsSustainability was an underlying issue for each of the four centres visited and was included in theCAPSA <strong>2011</strong> conference theme Roads of the Future and in the conference focus areas:• Reducing energy consumption in the construction of bituminous layers• Reducing the impact of road building activities on the environment• Designing for extended performance of asphalt• Flexible pavement systems for extended life• Meeting the needs of societyV4-2 Page 91
