APERÇU

Veuillez noter :
This course is held online over 2 days on the following schedule (All times in Eastern Time Zone):

9:30 am to 5:30 pm Eastern (Will include the usual breaks)

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 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 & sophisticated construction practices is best achieved with a thorough understanding of material properties & asphalt mix design. Engineers & technical managers are faced with the challenge of maintaining the investment in highways, airport runways, urban roads, parking areas & access roads in many developments. An understanding of the considerations for the design & construction of an asphalt pavement & of the factors that influence its deterioration is essential to make technically & economically feasible decisions regarding the design of asphalt mixes. 

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

Course Outline:

  • Role of Asphalt Mixes in Pavement Life
  • Aggregates and their Characteristics
  • Asphalt Mix Design Considerations
  • Asphalt Binder-SHRP Material Selection
  • Other Available Resources
  • Design Requirements for Marshall and Superpave Mixes
  • Designing Mixes with RAP
  • Quality Management in the Field
  • Resurfacing
  • Specifications - Mixing, Tests, Paving and Compaction
