Thin Overlay Guidelines: Project Selection, Design, and Construction

Thin hot mix asphalt (HMA) overlays are cost-effective, high-performance maintenance treatments. They can be laid at 1.0 to 0.5 inches thick and consist of quality aggregate and binder materials. The costs are generally more (per ton) than conventional overlay mixes; however, due to their thin application they cost less per square yard. This guidebook is based on the publication Austin District’s Guidelines on the Use of Thin Surface Mixes (TSMs). The authors have permission to reuse the content. This publication expands the discussion to other types of thin overlays and incorporates findings from project 0-6742. Sections include: What to look for and avoid in candidate projects; Materials and design; and Tips for successful construction.
