NAPA Webinars

Perpetual Pavements by Design and Conversion

Date: Tuesday, May 24, 2022

Time:  2:00 pm to 3:30 pm EDT

Speaker: Dr. Dave Timm, Professor of Civil and Engineering, Auburn University

Description: An asphalt perpetual pavement, properly designed and constructed, lasts longer than 50 years without requiring major structural rehabilitation or reconstruction, and needs only periodic surface renewal in response to distress confined to the top of the pavement. This webinar will discuss material and design selection, current perpetual pavement thickness practices, and present the latest award-winning perpetual pavements.

Attendees will be able to :

• Design criteria needed to achieve an asphalt perpetual pavement.
• Understand pavement concepts to compute maximum pavement thicknesses.
• Use modern computational design tools for perpetual pavements.
• See the latest award-winning perpetual pavements.

The Results Are In: NAPA and FHWA's Recycled Materials and Warm Mix Survey

Date: Wednesday, May 25, 2022

Time:  2:00 pm to 3:30 pm EDT

Speakers: Tim Aschenbrener, P.E., Federal Highway Administration, Joseph Shacat, Director, Sustainable Pavements, NAPA and Brett Williams, Director, Engineering & Technical Support, NAPA

Description: Since 2009, NAPA and FHWA have been collecting data on the use of recycled materials and warm-mix asphalt (WMA) technologies in the asphalt pavement industry. This webinar will provide the latest data on the use of materials such as reclaimed asphalt pavement (RAP), recycled asphalt shingles, (RAS), WMA and more.

Attendees will be able to :

1. Learn how the survey supports and enhances FHWA’s programmatic goals
2. Understand historical trends in the use of recycled materials and WMA
3. Quantify the economic and environmental impacts of using WMA and recycled materials in asphalt mixtures

An Introduction to LCCA and LCA – The Tools of the Trade for Life Cycle Thinking

Date: Monday, June 6, 2022

Time:  11:00 am to 12:30 pm EDT

Speakers: Joseph Shacat, Director, Sustainable Pavements, NAPA, Bill Buttlar, P.E., Glen Barton Chair in Flexible Pavement Technology, University of Missouri and John Harvey, Professor, Civil and Environmental Engineering, University of California, Davis

Description: Life cycle thinking provides a framework for understanding the economic and environmental aspects of a product over its complete life cycle. The pavement community commonly uses life cycle cost analysis (LCCA) to understand agency costs and user costs throughout the entire life cycle of a pavement. Agencies and other stakeholders are also starting to use life cycle assessments (LCAs) to quantify the potential environmental impacts of pavement designs at both an individual project level and a network level. This webinar will provide an overview of LCCA and LCA, with a focus on how these tools are applied to pavements to aid decision-making. 

Attendees will be able to :

1. Understand the concept of life cycle thinking in terms of pavement design and asset management
2. Learn how LCCA is used to quantify owner costs and user costs for pavement projects
3. Learn how LCA can inform the environmental benefits and tradeoffs associated with decisions related to pavement materials, design, construction, and maintenance strategies

PDHs: Professional engineers (PEs) who register and attend the entire webinar as an individual will be awarded up to 1.5 Professional Development Hours (PDHs). APA/NAPA’s webinar program awards PDH credits only to the registered individual, and not to other members of a group that view the webinar together.

June NAPA Member Briefing

Date: Thursday, June 9, 2022

Time:  11:30 am to 12:30 pm EST

Speakers: NAPA Staff

Description: Please join us for the latest NAPA updates. Open to NAPA Members only.

PAVEXpress Overview

Date: Thursday, June 16, 2022

Time:  2:00 pm to 3:30 pm EDT

Speaker: Danny Gierhart, P.E., Southeastern Regional Engineer, Asphalt Institute

Description: This presentation will give a brief overview of PAVEXpress, a free, web-based flexural and rigid pavement design software. This wbeinar will focus on the asphalt pavement thickness design portion of PAVEXPress which is based on the 1993 AASHTO Guide for Design of Pavement Structures.

Attendees will be able to :

1. How to access PAVEXpress and use it for pavement thickness design.
2. Learn to quickly evaluate various pavement design considerations.
3. Learn to evaluate the cost effectiveness of different designs which are structurally equivalent.

Asphalt Production & Construction

Date: Tuesday, September 13, 2022

Time:  2:00 pm to 3:30 pm EDT

Speakers: Steve McReynolds, Director of Operations, Asphalt Testing Solutions & Engineering and TJ Young, Production Manager, Duval Asphalt

Description: Civil and geotechnical engineers often specify asphalt for projects but don’t always get the opportunity to learn about production and construction 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 will be able to :

1. How asphalt is produced
2. How asphalt is constructed
3. Ways to improve the end product through design considerations

PDHs: Professional engineers (PEs) who register and attend the entire webinar as an individual will be awarded up to 1.5 Professional Development Hours (PDHs). APA/NAPA’s webinar program awards PDH credits only to the registered individual, and not to other members of a group that view the webinar together.
