Asphalt Density: The Myths, The Truths, The Lessons Learned

Date: 29 January 2021

Time: 10h00 – 12h00

Place: Via Zoom (See link below)

Asphalt (AC) in the 21st Century is very different from asphalt made 100 years ago. With binder modification, sophisticated aggregate crushing techniques, a plethora of additives and the introduction of nano technology, asphalt (AC) has rapidly  become a “super-construction material”. However, it still requires paving and compacting, and the technology in this activity has also modernised dramatically. The achievement of density of the asphalt layer is the subject of this webinar and the Society for Asphalt Technology invites you to attend and enjoy our webinar which addresses some finer details of how asphalt density is achieved in these modern times.

This webinar has been registered for CPD accreditation. CPD Certificate Number will be available on the day.
