The use of a new Ammann plant is helping to improve RAP usage in China with the manufacturer and the Chinese Government working together to gather and evaluate production data. A key Ammann customer in China is helping pave the way for the expanded use of recycled asphalt pavement (RAP) in the country’s road projects. Tianjin TianHeJianLing Road & Bridge Engineering Technology is a pioneer in the use of RAP in China. The mixes its Ammann ABA UniBatch and Uniglobe asphalt plants produce are being scrutinised

There are important methods aimed at the reuse and recycling of reclaimed asphalt pavement (RAP) a number of problems have to be solved however, mainly concerning the elimination of moisture content and how best to heat the RAP without damaging the binder. When RAP is used in percentages of up to 30-40% of the final mix, heating can be carried out through direct contact with hot aggregates. On the other hand, in order to use higher RAP percentages, up to 100%, the plant has to be fitted with a specific h
