WHAT'S NEW AT CAPA
Warm Mix Asphalt – Hot Topic at SAPA Mid Year Meeting – {from State Asphalt Pavement Association (SAPA) Mid Year Meeting, August 8-10, 2010} There are now approximately 23 states with permissive specifications that allow warm mix asphalt (WMA), including Alabama. All but 9 states have had pilot WMA projects. It is expected that 30 Million tons of WMA will be placed this year in the USA. The FHWA is very supportive of the use of WMA and is encouraging its implementation through its “Every Day Counts” program. NAPA Chairman Larry Lemon from Haskell Lemon Construction Co. in Oklahoma stated that his company has 5 asphalt material plants and produces 800,000 tons of asphalt materials per year. Each plant is now equipped with WMA foaming technology. Larry feels WMA is a superior product from a field workability, compaction, and performance standpoint.
Program Topics: This seminar will provide an overview of asphalt pavement design. Current CDOT asphalt pavement design procuderes will be presented and case study examples explained. Guidance on local agency pavement design will be provided. Work CDOT is doing on a new Mechanistic Empirical Pavement Design Guide (MEPDG) will be discussed with overview information on Perpetual Pavement designs. Presenters: Jay Goldbaum, CDOT Pavement Design Program Manager, Damon Thomas, CTL/Thompson, Jim Noll, Kumar & Associates
