Book Description

Nineteen test sections were constructed by the Arizona Department of Transportation (ADOT) as part of Strategic Highway Research Program (SHRP) Specific Pavement Studies (SPS)-6 experiment. The SPS-6 program addresses the rehabilitation of jointed portland cement concrete pavement. The objective of the SPS-6 experiment is to develop improved performance prediction models to be used for determining the additional pavement life that can be expected from the application of a variety of JCP pavement rehabilitation methods, ranging from minimal to maximum investment. Construction of the 19 SPS-6 test sections was successfully incorporated in ADOT project IR-40-4(123) on I-40 at Flagstaff. Eight of the 19 test sections meet the basic SHRP requirements for the experiment. The additional 11 sections were designed by ADOT to evaluate features that are not included in the SHRP experiment design.

Book Description

The Specific Pavement Studies 6 (SPS-6) experiment, "Rehabilitation of Jointed Portland Cement Concrete Pavements," was designed as a controlled field experiment that focuses on the study of specific rehabilitation design features of jointed plain concrete pavements (JPCP) and jointed reinforced concrete pavements (JRCP). This experiment examines the effects of climatic regions (wet-freeze, wet-no freeze, dry-freeze, or dry-no freeze), type of concrete pavement (plain or reinforced), condition of existing pavement prior to rehabilitation (fair or poor), and traffic rate (as a covariant), incorporating the different methods of rehabilitation with and without asphalt concrete (AC) overlays. This report documents the first comprehensive review and evaluation of the SPS-6 experiment.

Book Description

Load transfer restoration (LTR) is a rehabilitation technique for increasing the load transfer capability of existing jointed portland cement concrete pavement by placement of dowel bars or other mechanical devices across joints and/or cracks that exhibit poor load transfer.
