The environmental and economic advantages of using RAP in asphalt materials are well known and widely publicised. RAP is now an important part of everyday asphalt production and as its use has become more widespread, the amount of RAP used in materials has naturally increased. If not carefully managed, higher percentages of RAP could result in inhomogeneous materials, laying/compaction difficulties and impaired asphalt performance. Higher percentages of RAP also demand increased mixing times and the use of softer grades of bitumen to compensate for the hard/aged RAP binder.
Rapfix® can help asphalt producers and contractors to produce and lay premium quality asphalt with significant quantities of RAP. Material produced with Rapfix® will provide long lasting, cost effective and environmentally friendly solutions for clients such as local governments, national road networks, etc.
