TRB will conduct a webinar on Tuesday, March 27, 2018 from 2:00 PM to 3:30 PM ET that features research from the National Cooperative Highway Research Program (NCHRP)’s Research Report 856: Specifying and Measuring Asphalt Pavement Density to Ensure Pavement Performance.

The in-place density of asphalt mixtures is the single most important property of the asphalt mixture in the pavement. This webinar will examine the current agency practices used to measure and specify the in-place density of asphalt pavements. Presenters will explore guiding principles to select measurement methods and requirements for in-place density. They will also identify the specific knowledge gaps in order to establish more comprehensive density standards.

Some registrants will need to pay $95 to attend this webinar.  Sign into to view registration information.

Webinar Presenter

  • Dale Decker, Dale S. Decker, LLC

Moderated by: Ed Harrigan, Transportation Research Board

Webinar Outline

  1. Overview of NCHRP
  1. State of the practice for measuring and specifying density of asphalt pavements
  2. Key construction parameters to specify and measure density
  3. Areas in which the process for determining density can be improved
  4. Question and answer session

The first 60 minutes of the webinar will be for presentations and the final 30 minutes will be reserved for audience questions. The Registered Continuing Education Program (RCEP) categorizes this webinar activity as relating to health, safety, and welfare including core technical.

Learning Objectives

At the end of this webinar, participants will be able to:

  • Describe state-of-the-practice for measurement and specification of density
  • Describe the key construction parameters for specifying and measuring density
  • Identify areas in which the process can be improved
