Participants will work on asphalt mix design suitable for different load and environmental conditions.

After participating in the course, you will be able to:

• • make critical decisions in the lab and on the construction projects using the background knowledge gained from the course
  • select asphalt and aggregate material knowing their effect on mixture properties
  • perform proportioning, volumetric analysis, mixture evaluation using the guidelines for the application of different mixture types
  • increase the useful life of your pavement by efficient asphalt mix design
  • analyze your specifications to understand how they affect the quality you receive

Designers actively involved in asphalt mix design, materials specifications and field management of asphalt mixes, geotechnical and materials engineers in government transport departments, project managers, maintenance engineers, technicians and technologists, contractors, construction inspectors, technical managers, consultants and municipal engineers with responsibility for asphalt pavements. This course is an excellent opportunity for those wishing to develop or increase their knowledge base of asphalt mix to build longer lasting pavements.

This interactive Training will be highly interactive, with opportunities to advance your opinions and ideas and will include;

• Lectures
• Workshop & Work Presentation
• Case Studies and Practical Exercise
• Videos and General Discussions
