Varm återvinning i asfaltverk: försök med bindlager på väg 40, delen Rya-Grandalen
Swedish National Road and Transport Research Institute.
2008 (Swedish)Report (Other academic)
Abstract [sv]

The interest in recycling of asphalt has increased a lot under the 1990s. In order to meet this interest a test of warm asphalt recycling in an asphalt plant was carried out in 1997. Recycled asphalt from Road 40 was mixed with newly-produced binder layer material of the type ABb 22. The test road was opened for traffic in the autumn of 1997. The test sections consist of both slow and high speed lanes (K1 and K2) on a motorway. The test road consists of totally six sections, four with pavement including granules (reclaimed asphalt pavement, RAP) and two reference sections with virgin asphalt mixture. The test sections contain 0, 20 and 40 per cent RAP, respectively. The binder is of bitumen, 70/100 in K1, and 160/220 in K2. In the base course (AG) layer, 40 per cent of RAP was mixed. The binder layer was trafficked the autumn of 1997 and the spring of 1998 till it was paved with a wearing course in the summer of 1998. The test road has been followed up in 1997, 1998, 1999, 2000 and 2007 by bore cores, rut depth, evenness and damages. The bore cores have been investigated by void content, indirect tensile strength, stiffness modulus, stability and durability (water sensitivity) as well as by ageing of extracted binder. In connection with the production of the materials both the asphalt material and the recycled asphalt were controlled. In connection with the paving it was observed that the mixes with RAP were more elastic and easier to pack than the reference sections where virgin asphalt material was used.
