Comparison of Predicted versus Actual Performance of the Arkansas SPS-2 Test Site
A concrete pavement test area containing 12 different typical sections was constructed on Interstate 30 in 1996 by the Arkansas Department of Transportation. The test area was part of the FHWA’s long term pavement performance (LTPP) program’s Specific Pavement Studies of concrete pavement (SPS-2). Performance data of the test sites was carefully collected by the Arkansas Department of Transportation (ARDOT) and FHWA periodically. Performance measures included roughness (IRI), faulting, cracking, and drainage. Data collected under the LTTP program served as a critical resource in developing the American Association of State Highway and Transportation Officials (AASHTO) Mechanistic-Empirical Pavement Design Guide (MEPDG). The performance of the Arkansas SPS-2 site was carefully evaluated each year until its reconstruction in 2014. The predicted versus actual performance of the test sections are reported herein using the mechanistic empirical pavement design guide (MEPDG). It was found that the MEPDG was more conservative than the actual performance for the Arkansas test sections. The MEPDG also placed greater value on widened slabs and concrete strength than was seen in the field.
