Course Description
Maximizing the performance of high quality materials and sophisticated construction practices is best achieved with a thorough understanding of material properties and asphalt mix design. Engineers and technical managers are faced with the challenge of maintaining, within shrinking budgets, the investment in highways, airport runways, urban roads, parking areas and access roads in many residential, commercial and industrial developments.
An understanding of the considerations for the design and construction of an asphalt pavement and of the factors that influence its deterioration is essential to make technically and economically feasible decisions regarding the design of asphalt mixes.
The Training Course Will Highlight ?
Participants will work on asphalt mix design suitable for different load and environmental conditions.
Training Objective
Participants will work on asphalt mix design suitable for different load and environmental conditions.
Target Audience
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.
