Påverkan av asfaltens egenskaper efter förbättrad konsistens - Mätningar med dynamisk skjuvreometer, DSR, på bitumen och asfaltbruk

Sammanfattning: Sustainable achievement is the overall objective of all road building undertakings. An important part of this is recycling. Reclaimed asphalt is not only renewable but contains vast volumes of finite resources and the interest for the recycling modes of operation is on the rise. However, the impact of additives and the production processes must not adversely affect the properties of the pavements on the road. The purpose of the thesis is to measure and assess viscoelastic properties of bitumen and bitumen-filler mastics with various additives that are considered to affect the consistency of asphalt during manufacture and the properties of finished asphalt.
