Development of Design Guide for Thin and Ultrathin Concrete Overlays of Existing Asphalt Pavements
http://www.pooledfund.org/Details/Study/389
Record Type: RiP

Thin (TCOAP) and ultra-thin (UTCOAP) concrete overlays of existing asphalt pavement (also known as whitetoppings) are a pavement rehabilitation option that has been increasing in popularity in the U.S. over the past 15 years. The primary purpose of this project is to create a unified national design guide for thin and ultrathin concrete overlays of existing asphalt pavements. This consists of the following distinct objectives: (1) Study and understand the field performance history of TCOAP and UTCOAP as demonstrated by various research test sections. These include current (and future) test sections at the Minnesota Road Research Facility (MnROAD), accelerated loading facility test sections (FHWA), and other test sections installed and monitored by various local, national and international agencies. (2) Develop a design guide for concrete overlays of existing asphalt pavements utilizing existing validated performance models, as well as new analytical models derived to address design aspects not currently considered in existing methods. The design guide will be based on mechanistic-empirical principles, including the effects of various concrete overlay and existing asphalt materials, panel thickness and geometry, joint opening and stiffness, traffic loads, and climates under which they must perform. (3) Create a user-friendly design guide software program and user's manual. The program format should be such that it could become a module in the future national Mechanistic-Empirical Pavement Design Guide (MEPDG) for highway pavements.
