TRAINING.

Overview

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, and mixture evaluation using the guidelines for the application of different mixture types
• Increase the service life of your pavement by efficient asphalt mix design
• Analyze your specifications to understand how they affect the quality you receive

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 the investment in highways, airport runways, urban roads, parking areas and access roads in many developments.

An understanding of the considerations for the design and construction of 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.

Participants will work on asphalt mix designs suitable for different loads and environmental conditions.
