The asphalt industry is the backbone of North American road building infrastructure. Now more than ever, questions of sustainability, materials development and application, technology adoption, environmental responsibility, and fiscal prudence are front of mind for decision-makers at departments of transportation and asphalt contracting firms alike. The drive to find improvements in each of these areas comes down to a single crucial point – innovation.

To now, the idea of innovation has been unfairly associated with an adverse amount of risk. “Too risky,” is the common refrain when a new and innovative method or application is brought to light. But is it? The construction industry in general, when it has demonstrated a willingness to innovate, has realized enormous levels of success and efficiency, and the asphalt segment is now primed to follow.The most crucial question is: Who drives innovation?

In this webinar, we welcome a panel of asphalt industry experts to discuss the question of innovation and both the degree to which our industry has been reticent to engage, and the process by which innovation—from the DOT, contractor, and materials developer sides—can begin to benefit and driven gains in the industry.

Shane Biddle
Hot Mix Supervisor, Delaware Department of Transportation

Shane has worked at the Delaware Department of Transportation Materials & Research Lab for almost 31 years. He started working in the Soils Lab while attending Delaware Tech, where he received an Associate Degree in Civil Engineering. Shane transferred to the Hot Mix section in 1995, and for the last 21 years served as Supervisor. The section includes Delaware DOT hot mix inspectors and research lab. Notably, Delaware is one of the few states that still have state employees testing hot mix for payment. Shane has been part of many innovations while working at Del DOT, from the implementation of SuperPave to the development of SMA, high rap and shingle mixes, rejuvenators, ground rubber and now performance testing. He currently performs APA, Ideal-CT and Texas Overlay testing on Del DOT approved mixes. As for now, the information collected is used for data building, so that the agency can implement a performance spec in the near future.
