REMIX ON TRIAL

Remixing, where a new roadwearing course is formed using a mixture of old and new materials will soon be a permitted alternative to traditional surfacing. Four trials have been conducted by the Department of Transport in Hampshire, Lancashire, Lincolnshire and Nottinghamshire. Results from these trials and the attitudes of maintenance engineers will determine whether the use of recycling techniques become more widespread. The advantage of remixing is that pavement rehabilitation is done in-place in a single operation. The existing pavement is first softened by preheating to between 140 and 170 degrees Celsius and then subjected to further heating by a band of heaters. It is then scarified, mixed with new materials and placed evenly to grade and slope, by a compacting screed. The formula for the admixture is based on the historical core analysis. The new material is either a hot mix, a graded aggregate, a binder or a rejuvenator. The admixture is transported to the Remixer and tipped into the receiving hopper in the same way as a conventional paver. Base material is heated to ensure a good bond with the recycled mix. (TRRL)
