One Hour Webinar
Description
The Virginia LTAP, in partnership with the Virginia Transportation Research Council (VTRC), the research leg of VDOT, invite you to join us for a one-hour lunch and learn event. This new series will showcase VTRC’s transportation innovation and research.
These monthly, one-hour events will take place at various locations across the Commonwealth from 12:00 pm to 1:00 pm. You may join remotely via Zoom or attend in-person. Lunch will be provided for those who attend in-person. Those attending in-person will also receive some swag.
TOPIC: Advances in Pavement Testing and Rehabilitation
Recent advances in pavement testing and rehabilitation include assessing the structural capacity of pavements using equipment traveling at traffic speeds and the use of pavement recycling techniques. VDOT is the lead agency of a pooled fund study where highway agencies from 23 states are conducting pavement structural testing using a Traffic Speed Deflection Device (TSDD). In addition to this leading role, VDOT has has completed testing on more than 7,000 miles of its pavement network using this system.
Testing with a TSDD can give an agency detailed information about the structural capacity of its pavement network that is more complete and can be obtained many times faster than previous methods. Where the TSDD testing shows pavements to be structurally deficient, pavement recycling techniques can be used for rehabilitation at lower cost and reduced environmental emissions. VDOT is a national leader in using pavement recycling techniques on higher volume routes (including I-81 and I-64) but could make better use of these techniques in other areas. This presentation will discuss these concepts and provide examples from case studies.
Instructor
Brian Diefenderfer
Brian Diefenderfer is a Principal Research Scientist at VTRC where he has worked for the last 20 years. His research focuses on pavement design, rehabilitation, and recycling techniques that can be used to reduce costs and improve the performance of VDOTs pavements network. Brian received his PhD in civil engineering from Virginia Tech in 2002 and is a Professional Engineer.
Who Should Attend
State and local transportation engineers & other professionals interested in advances in pavement testing and rehabilitation.

Special Registration Instructions for Employees of the Virginia Department of Transportation
VDOT employees must register through the VDOT Virtual Campus. Registration fees and related expenses for all VDOT employees will be paid from the VDOT Learning Services Center budget. Registrants should contact their District Training Coordinator or the VDOT Learning Services Center (Central Office employees) for instructions on how to seek reimbursement for travel expenses.
Due to current travel restrictions, VDOT employees are strongly encouraged to attend U. Va. TTA workshops on a day trip basis. Overnight travel requires permission from your District Administrator or Chief -- and in some cases higher levels of authority. If you require overnight lodging to attend a U. Va. TTA workshop, consult with your supervisor, District Training Coordinator, or VDOT Learning Services Center on travel approval procedures.
