Design and Construction of Surfacing Seals in PE.

The three-day course “Design, Application and Construction of Surfacing Seals” for roads, which was held in Port Elizabeth on 13-15 September, included all aspects of seal design for conventional and modified binders using the Revised TRH3.

The intensive, yet informal presentation included:

* Pavement deterioration

* Condition assessment

* Project identification and prioritization

* Binders and materials

* Selection of appropriate measures

* Seal design principles

* Workshop using TRH3

* Labour intensive seals

* Geotextile seals

* Basic site control

* An overview of surfacing equipment

* Types of surfacing treatments

* Conversion factors, formulae, and calculations

The 21 delegates attending the course covered the full spectrum of Road Engineering, including Consulting Engineers, Contractors, Provincial Roads, the National Roads Agency and a Supplier, Colas, and were all very complimentary of the lecturer, Gerrie van Zyl, and the vibrant manner in which it  was presented.
