Small aggregate, polymer modifiers key to new Texas thin lift mixes

New pavements are being developed by researchers at the Texas A&M Transportation Institute (TTI) and the Texas Department of Transportation (TDOT) that are much thinner than traditional overlays and are made with high quality stones and polymer modified asphalt that are expected to last longer and require less maintenance. State, county and city officials are eager to use overlay in the hopes of saving money and inconvenience, as well as providing smoother rides. Details of the pavement testing and mixing leading up to its development, as well as its benefits, are presented here.
