In honor of ComputerScienceEducationWeek, this blog reviews how computers play a big part in ADOT project plans:
We draw them, we review them, and we use them during construction, because they tell us what to do. Roadway plans are common around ADOT amongst designers and construction personnel, but you’ve probably never seen them for yourself. Here are just a few things that we include in plan sets.Pavement structural sections describe the layers of a roadway.
