Reclaiming Istanbul: Reviving the Public Sphere Through Infrastructure

Since the introduction of the coffee houses, Istanbul gained an important element to form a public sphere. These places enhanced the forming of a public opinion which is a crucial aspect of a democratic society. In the Ottoman empire these places were even seen as a nest for the opposition. Nowadays public spaces are threatened by a...

HighRAC workshop

With the increasing drain on natural resources and resulting aim to reduce the environmental impact of road engineering, the use of reclaimed asphalt in fresh asphalt becomes more and more important. Despite the experience in using RAC, there are still many questions regarding the effect of RAC on the technical and environmental performance of...

Reintroducing the intrinsic seld-healing properties in reclaimed asphalt by rejuvenation

Reclaimed Asphalt (RA) is one of the largest fractions of raw materials used in road construction today. Probably over 90% of the total RA in the Netherlands is being reused in new asphalt constructions. RA contains aggregates coated with very hard bitumen (penetration grade of 10-20). During service, the bituminous binder loses its flexibility...

The Influence of Ageing on the Fatigue and Healing Properties of Bituminous Mortars

For asphalt pavement design in Belgium, healing is taken into account as a standard shift factor, representing the effect of rest periods between loadings of traffic. Because nowadays Reclaimed Asphalt Aggregate (RA) is widely used in hot mixtures, a new validation of the healing factor is needed. Given the lack of test results and a standard...
