wisconsindot.govFHWA and AASHTO have made intersection safety a high priority. The objective is to improve the safety and operation of intersections. When compared to signalized intersections, studies by the Insurance Institute for Highway Safety [1] show that roundabouts typically reduce overall delay and congestion, increase capacity, and improve safety.
Hot Mix Asphalt (HMA) Selection Guidance - December 2017
www.michigan.govas signalized intersections and other areas of stop/start traffic use the pay item entitled High Stress Hot Mix Asphalt Mixture. The difference between the High Stress HMA Mixture and the typical HMA pay item is the Performance Graded binder. For High Stress Mixtures, increase the high temperature binder by one grade and add the polymer.

Minimum Width of Sidewalks Sidewalks require a minimum width of 5.0 feet if set back from the curb or 6.0 feet if at the curb face. Any width less than this does not meet the minimum requirements for people with disabilities. Walking is a social activity.
