Question: In your April column (“ADA Corner,” Public Works April 2014 issue, page 20) you expressed a preference for asphalt trails over concrete trails. I am in the process of installing a wide sidewalk at our county nursing home. I would like something that’s durable and gives the best ride to the residents. Our existing asphalt walks have eroded and developed a pebbly surface, which is definitely not the smoothest surface for wheelchairs and walkers. Why do you prefer asphalt over concrete? — Mike, Wisconsin
Answer: I’m so glad you sent this question! I was only referring to the trails that are so often used by runners. For them, the asphalt is softer to land on. For actual facilities, concrete is the preferred choice. Thank you for giving me the opportunity to clarify this issue.
