Intro to TRH3 / Sabita Manual 40: Design & Construction of Surface Seals

Intro to TRH3 / Sabita Manual 40: Design & Construction of Surface Seals


Cutting edge technology and products are employed in the bituminous surfacing of South Africa’s roads. The industry prides itself on being up to date with the latest local and global wisdom in surfacing treatments.

As practitioners it is up to each one of us to ensure that our knowledge remains relevant. To this end, the Society for Asphalt Technology has invited some of the country’s leading experts to unpack the latest guidelines on surface seals.

The existing guidelines for bituminous surfacing treatments have been revised based on research, performance studies, investigations into premature failure, updated specifications, and the development of improved bituminous binders over the past decade. SABITA Manual 40 (2020) has replaced the national guideline document TRH3 (2007) for the selection, design and construction of surfacing seals. SABITA Manual 40 also replaces the existing Manuals 10 and 28.

We invite you to participate in our comprehensive workshop covering all aspects of SABITA Manual 40.

DATE Thursday, 25 February 2021
TIME  09.00 – 13.00 

We are delighted to have well-known professionals lined up to expand on the new guidelines in this four-hour session. Please view the Presenter Schedule at the bottom of this page.
