Performance Assessment of Concrete Roads in Sweden
Results from follow-up studies of Swedish concrete roads are compiled and analysed regarding rutting, abrasion, friction, longitudinal evenness, noise and macro-texture. The four concrete roads included in the analysis have all been constructed in the 1990s and situated near Arlanda, Falkenberg, Fastarp and Eskilstuna. Differences between the roads are identified and examined and a discussion on long-term performance of the properties is also included. The paper aims at assessing the improved method practised when constructing the four concrete roads, which involved the use of dowelled joints, higher concrete strength, more wear resistant aggregate material, smaller maximum aggregate size and noise reducing surface treatments. The results show that the concrete roads constructed in Sweden after 1990 are performing well regarding the properties included in the study. The rut growth varies from non-significant up to 0.6 mm/year. The changes in longitudinal evenness are small with only one road showing a significant increase. The friction values for the four roads varied from 0.6-0.8.
