Asphalt Mix Design Training Course
Introduction:
Course Objectives:
After participating in the course, you will be able to present methods of design for asphalt mix suitable for various applications.:
- 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
Who Should Attend?
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.
