When maintaining roadways, it’s important to include the shoulders as part of the process. If untreated, the shoulder will deteriorate causing the pavement edges to weaken and allowing moisture penetration into the roadway, ultimately affecting the road itself. The Arizona Department of Transportation (ADOT) kept this in mind on one of their recent projects on I-8 outside of Gila Bend, Ariz. ADOT contracted the work out, which consisted of a mill-and-fill of the roadway, construction of guardrails, replacement of bridge dados and other work, including crack sealing the shoulders.
