Designing roundabouts with heavy vehicles in mind presents various challenges, including considerations for camber, turning space, approach and exit geometry, and more. However, designers possess a valuable tool in their toolkit – mountable aprons.  

While maintaining the roundabout’s defined outline, these mountable paved edges serve as a discreet yet effective solution. They enable trucks to navigate the roundabout by driving over a designated part, facilitating smooth and efficient movements. 

Check out this video from Montana’s Department of Transport with practical insights into the use of mountable aprons, providing valuable perspectives on their role in enhancing the functionality of roundabouts for heavy vehicle traffic.
