Abstract [sv]

Cored specimens and asphalt mass from rubber asphalt pavement laid in 2007 on the ring road in Malmö (E6) has been sent to VTI for analysis. The investigations have focused on assessing the performance characteristics: - Stability by Dynamic creep test according to FAS 468 - Flexibility by Stiffness Modulus according to FAS 454 - Abrasion Resistance by Prall test according to FAS 471 - Durability by Water Sensitivity according to FAS 446 and Winter conditioning test according to VTI methodology - Fatigue by Indirect tensile test on cylindrical specimens according to VTI methodology - Crack propagation by WTT equipment according to VTI methodology. In addition to these tests also master curves by stiffness modulus have been developed. Master curves are produced to make an overall assessment of the materials under different load and temperature conditions.
