Ensure that the project mix materialises on site by sticking to some basic principles. This presentation enlarges on the basics such as quality control of mixes containing reclaimed asphalt (RA), consistency of RA fractions in the mix, aspects to consider at stockpiles, moisture content, and finally sampling, testing and acceptance control as for conventional asphalt mixes.

What does “nano-technology” mean? What are the problems we need to solve in a South African context? Prof Jordaan takes us from the basics of road pavement engineering and the mind shift required to move from conservative and expensive methodologies to exploring “new-age” nanotechnologies. This detailed presentation covers everything from current material design practices to recommendations for efficient and cost effective alternatives, together with project examples.

With the advent of the new Revision Of COTO Standard Specifications For Road & Bridge Works For State Road Authorities, the onus for the submission of asphalt mix designs now lies with the contractor. A thorough and sound understanding of the principles and goals involved in the mix design procedure is required by all Client Bodies, Consulting Engineers, and now specifically, the Contracting fraternity. The goal is to avoid fruitless and wasteful interventions.
