After 26 years of service, I am confident that now is the time to pursue new personal and professional interests." Gehl says: "Rick has a deep understanding of Astec's business and operations as well as the construction industry, which make him an excellent choice to lead Astec through this transition period.""On behalf of the Board, I thank Ben for his many contributions to the Company over the years and wish him success in the future."
