An Introduction to the Bailey Method

Asphalt AcademyWebinars

Session Sub-title:

Optimizing Volumetrics and HMA Compactability Utilizing the Bailey Method

Description:

Have you ever wondered why your volumetric test results were passing in the morning and failing miserably by noon? This webinar will explain several reasons why this can occur. This webinar will cover the basics of VMA and Air Voids and explain how absorption affects your results. We will discuss the Baily Method, which is an innovative aggregate and mixture analysis system that can accurately estimate the effects of aggregate packing and how that affects mix volumetrics. The four basic principles of the Baily Method will be introduced to help explain mysterious volumetric changes that can occur in field produced mixtures.

Outline

  • Understanding Volumetric Testing In The Field
  • Explaining Bailey Aggregate Packing Characteristics
  • Defining Mixture Type – Baily Principle #1
  • Coarse Aggregate Ratio – Principle #2
  • Fine Aggregate Coarse Ratio – Principle #3
  • Fine Aggregate Fine Ratio – Principle #4
  • Summarize Mixture Effects Due To Gradation Change

Fees & Registration:

Professional Development Hours:

  • 2 hrs., 2 PDHs

A PDH Certificate is available upon request after you complete the session by sending an email to ai_webinars@asphaltinstitute.org with the name of the webinar and full name you used to register.

Instructor(s):

  • Mark Blow, P.E., Regional Engineer, Asphalt Institute

Who Should Attend:

This webinar is intended for inspectors, technicians, engineers, project managers, and consultants who are actively engaged in asphalt mix design and quality control operations of hot mix asphalt plants. Aggregate manufacturers involved with the production of mineral aggregate for hot mix use would also benefit.

Notes:
