Cold recycling of asphalt at a central plant: follow up of test roads in Halland, Södermanland and Gävleborg counties


Cold recycling of asphalt is a resource-saving technology because the materials do not need to be warmed up. Moreover, by using this technique, up to 100 per cent reclaimed asphalt concrete (RA) could be recycled. However, in order to achieve good results, the old RA should be processed in a proper manner. The report presents results of tests carried out on road N-714, part Vessigebro–Ätrafors and road N 530, part Såghuset–Skönhult in Halland in addition to road D-976, Strängnäs and road D-957, Vansö in Södermanland. Moreover, this report presents results of tests performed on road X-583, part Ljusne–Sandarne in Gävleborg. The mechanical properties have been investigated by indirect tensile strength and stiffness modulus for RA mixtures and drill cores. The tests results showed that part of the damage that may be encountered when using cold recycled asphalt coatings can be in the form of loss of surface materials, mechanical damage due to relatively soft road surfaces and unevenness of the road surface.
