GETTING TO KNOW UDOT Howard Anderson, P.E. STATE ASPHALT ENGINEER For the first in the new series “Getting to Know UDOT,” we sat down with Howard Anderson to learn more about his career and what he sees for the future of asphalt. The goal of this series is to learn more about the people behind UDOT and all the work they do to enhance our quality of life with roads, transit, and active transportation. We enjoyed getting to know Howard and understanding his responsibilities as a State Asphalt Engineer. The following is an excerpt from our conversation. Tell us about your background. I graduated from the University of Nevada-Reno with a bachelor’s and master’s degree in civil engineering. My master’s thesis was sponsored by the Nevada DOT on the use of polymers in asphalt materials. I like working with people and trying to understand why our materials behave the way they do. How long have you worked with UDOT — has it always been in asphalt? I have worked for UDOT for over 30 years, mostly in the asphalt area. Over the course of your career, what has changed? The use of computers, cell phones, and technology has greatly changed how we do our business. Laboratory equipment, such as rut testers and DSRs, has improved, giving us a better ability to test the materials for quality and performance. What are you currently working on at UDOT? I am working with the industry to implement a UDOT performance test for asphalt pavement cracking. I am also engaged in documenting our asphalt pavement for stripping and documenting the best additives for long-term performance. In addition, I am working with higher polymer mixes for improved durability and performance that can be placed in thin or thick lift applications. What are the “big things” on the horizon that you feel will change asphalt in the future? High polymer high-density mixes are game changers. These mixes will last longer and perform better than traditional asphalt mixes. Can you share an experience where you/UDOT worked with UAPA to achieve something? Recently, we worked with UAPA to improve our Mix Design Approval Manual of Instruction. We also worked together to improve our Longitudinal Joint specification. 20
