Development of an Improved Design Procedure for Unbonded Concrete Overlays

The primary purpose of this project is to create a unified national design guide for unbonded concrete overlays of existing concrete and composite pavements. This consists of the following distinct objectives: (1) Study and understand the field performance history of unbonded concrete overlays of existing concrete or composite pavements (UCOCP) as demonstrated by various test sections and in-service pavements. (2) Determine suitable separator layer (interlayer) materials and properties to insure long term performance of UCOCP systems. (3) Develop a design procedure for unbonded concrete overlays of existing concrete and composite pavements utilizing existing validated performance models, as well as new analytical models derived to address deficient or missing design parameters in existing methods. The design guide will be based on mechanistic-empirical principles, including the effects of various concrete overlay materials, separator layer (interlayer) types, panel thickness (4" to 10") and panel size, joint load transfer mechanisms, traffic loads, and climates (nation-wide) in which they must perform.
