LLCA End of Life
Date: Wednesday, October 1; 1:00 p.m. CST
Speaker: Jim Musselman, Senior Engineer - National Center for Asphalt Technology (NCAT)NAPA Webinars
A Life Cycle Cost Analysis (LCCA) is a technique used by many state highway agencies to evaluate the overall expected costs of competing pavement alternatives, primarily between asphalt and concrete design. LCCAs consider initial construction costs, along with future anticipated costs such as maintenance and rehabilitation costs, as well as user costs. But what happens at the end of a pavement’s life, and how should that be properly accounted for in an LCCA?
This webinar will focus on the best methods of addressing pavement end of life issues when conducting a LCCA, ranging from making certain that the remaining service life of a pavement is properly addressed, to understanding the importance of considering what actually happens to a pavement when it reaches its terminal serviceability, and how that needs to be included in an LCCA.
- Learn the difference between residual value of a pavement versus its remaining service life value
- Understand how to determine the remaining service life value of a pavement and the importance of applying that concept to all pavement layers
- Understand the importance of assuring that the LCCA analysis period be long enough to make sure that one of the pavement alternatives reaches its terminal serviceability, and that the cost of the remediation be accounted for as a future cost during the analysis A Life Cycle Cost Analysis (LCCA) is a technique used by many state highway agencies to evaluate the overall expected costs of competing pavement alternatives, primarily between asphalt and concrete design.

Recycled Asphalt Pavements (RAP) Part 2: Mix Design and Laboratory Performance Testing
Date: Wednesday, October 7; 2:00 p.m. CST
Speaker: Scott Quire, Bluegrass Testing LaboratoriesNAPA Webinars
Asphalt mixtures containing RAP, when designed utilizing proper design principles and produced in consideration of production constraints have demonstrated excellent performance. This part of the webinar will focus on mix designs utilizing RAP, the level of mix design analysis needed as RAP percentages increase, the production variables to consider as RAP percentages increase and performance testing of asphalt mixes containing RAP. This webinar is RCEP approved.
- Review of design considerations as RAP percentages increase.
- Learn about the approach to mix design methodology for RAP mixtures.
- Performance testing of asphalt mixtures with RAP.
- The plant considerations for asphalt mix production at various levels of RAP utilization.
Asphalt Performance Tests: Specimen Fabrication Practices
Date: October 14; 1:00 p.m. CST
Speaker: Dr. Jo E. Sias, Professor of Civil Engineering - University of New Hampshire
The use of mixture performance tests is becoming more widespread for mixture design and QC/QA processes. There are guidelines for conducting these tests, but they do not all provide uniform or comprehensive direction for fabricating test specimens. This webinar will provide participants with an understanding of variables in specimen fabrication that could impact performance test results, procedures and practices that have been developed for improved consistency in fabricating performance test specimens, and common challenges and knowledge gaps.
This webinar draws on research from the National Cooperative Highway Research Program (NCHRP) Synthesis Report 552: Practices for Fabricating Asphalt Specimens for Performance Testing in Laboratories.
- Identify variables in fabrication processes of asphalt performance test specimens
- Learn potential impacts on performance test results and practices for consistent specimen fabrication
- Understand knowledge gaps and future research needs in improving specimen fabrication practices for asphalt lab performance tests
Recycled Asphalt Pavements (RAP) Part 3: Field Performance and the User Experience
Date: Wednesday, October 28; 2:00 p.m. CST
Speaker: Dr. Randy West, Director - National Center for Asphalt Technology (NCAT) at Auburn University; Jim Musselman, Senior Engineer - National Center for Asphalt Technology (NCAT) at Auburn University; and Abdul Dahhan, Vice President - Chicago Testing Laboratory, Inc. NAPA Webinars
Asphalt pavements are the most recycled material in the U.S., primarily because asphalt mixes that contain RAP have good performance histories. This part of the webinar will highlight studies on field performance conducted by numerous state DOTs, the Federal Highway Administration, and various pavement research organizations including the National Center for Asphalt Technology. The segment will also highlight the experiences of two pavement engineer veterans who will provide long-term perspectives of using RAP in asphalt mixtures from the Illinois DOT and the Florida DOT. This webinar is RCEP approved.
- Documented field performance of asphalt mixtures containing RAP.
- What applications are best suited for higher RAP content.
- What applications are best suited for higher RAP content 3. The impact specification requirements have on usage and performance of RAP.
- Agency perspectives on the benefits and concerns with using RAP.
Asphalt 101 for Civil and Geotechnical Engineers: Asphalt Production and Construction
Date: November 4; 2:00 p.m. CST
Speaker: TJ Young, Production Manager - Duval Asphalt and Steve McReynolds, Director of Operations - Asphalt Testing Solutions & Engineering
Civil and geotechnical engineers often specify asphalt for projects and but don’t always get the opportunity to learn about production of the product. This webinar will take attendees behind the scenes using drone video to explore the asphalt production process leading up to delivery on-site. Furthering this educational opportunity, engineers will learn about the construction process by watching asphalt placement and hearing tips to specify and design high-quality jobs presented by experienced asphalt experts.
Attendees should expect to learn:
- How asphalt is produced
- How asphalt is laid
- Ways to improve the end product through design considerations
This webinar is RCEP approved.
Accelerated Asphalt Road Construction for Engineers and Owners
Date: Tuesday, November 10; 2:00–3:30 p.m. CST
Speaker: David Newcomb, P.E., Ph.D., Division Head - Materials & Pavements and Matt Wilson, Director of Marketing, Communication, and Government Affairs -Barriere Construction Co., L.L.C. NAPA Webinars
Asphalt pavements are quick to construct, but this traditional wisdom has rarely been quantified — until recently. Using a case study, learn how researchers quantify speed of construction with user costs and local business impacts and learn also from a contractor on how asphalt’s speed of construction was a winning component to their bid. Agencies can gain a more holistic view of the total economic impact of a construction project. This analysis helps the agency make an informed decision surrounding the economic and construction costs associated with large pavement projects. This webinar is RCEP approved.
- Contractors’ strategies for accelerating asphalt road construction.
- The importance of accelerated asphalt road construction for the future of the U.S. infrastructure.
- How agencies and contractors have worked together to get the most out of time spent in work zones.
