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.

SAT was pleased to present to industry the Third Edition of TG2 for BSMs, incorporating 18 years of experience and new technologies. The first TG2 guideline was published in 2002 for foamed bitumen only and the Second Edition for BSMs in 2009.

This technology has now been implemented globally and the manual has been assembled using evaluation data from abundant project investigations and long-term pavement performance records. This has allowed the DEMAC materials classification system to be updated, mix design procedures to be overhauled and refined, and the Pavement Number method to be updated. At the same time, a mechanistic design function has been developed for BSM pavement structures.
