“…However, this section experienced drainage issues and joint sealant damage, potentially contributing to distress formation resulting from erosion of the interlayer. • Faulting can develop after a longitudinal crack initiates (at the transverse joint in the wheelpath) from permanent deformation in the interlayer (6). This can be seen for Section 6-9107.…”

Unbonded concrete overlay of concrete pavement (UBOL) is an effective rehabilitation method involving the construction of a new concrete pavement over a deteriorated concrete pavement, separated by an interlayer. While UBOL is used in practice to improve the structural capacity of existing concrete pavements, the performance of the interlayer is not currently accounted for in the pavement mechanistic–empirical design process. Therefore, the objective of this research is to improve prediction of UBOL performance by accounting for the effects of asphalt interlayer consolidation on the development of longitudinal cracks in the wheelpath. First, a laboratory investigation was performed using beams cut from in-service pavements in Michigan, Minnesota, and Pennsylvania to assess the susceptibility of permanent deformation of asphalt interlayers. This data was utilized in conjunction with a finite element analysis to develop/calibrate a permanent deformation prediction model for dense graded asphalt interlayers. The framework of the model follows that of the permanent deformation prediction model for asphalt surface pavements incorporated into the American Association of State Highway and Transportation Officials (AASHTO) Mechanistic–Empirical Pavement Design Guide. In addition, a field analysis was conducted, using the Long-Term Pavement Performance (LTPP) database, to assess longitudinal cracking in the wheelpath caused by permanent deformation in asphalt interlayers. The laboratory-calibrated permanent deformation model was then validated using the performance data for UBOLs in the LTPP database and deformation thresholds for asphalt interlayers were established. This research resulted in the development of a framework for the prediction of longitudinal crack development in UBOLs because of permanent deformation in the asphalt interlayer.

“…A study was conducted to determine the adequacy of using the UBOL module in Pavement ME for predicting the development of distress in UBOL. It was found that the approach is inadequate because of the inability of Pavement ME to accurately model interlayer damage (interlayer is neglected), and the resulting surface distresses that form in UBOL structures (6).…”

“…Joints can deploy through just the PCC layer, both the overlay and the underlying asphalt layer, or can have both depths of deployment along the same overlay. The different depths of joint deployment can be estimated based on the flexural stiffness ratio (FSR) between the overlay and the asphalt layer and the panel size ( 4,10 ). The depth of joint deployment dictates the layer that will be eroded and pumped.…”

“…The interfacial bond can deteriorate over time, and water can seep in along the interface and become trapped. This contributes to stripping and the deterioration of the structural integrity of the asphalt, which leads to pumping and faulting ( 10 ). If the transverse joint propagates through the asphalt layer, then the PCC and asphalt act as a monolithic structure and faulting develops because of pumping of the granular material below the asphalt or the subgrade material, as shown in Figure 1 b .…”

Transverse joint faulting is a common distress in bonded concrete overlays of asphalt pavements (BCOAs), also known as whitetopping. However, to date, there is no predictive faulting model available for these structures. To account for conditions unique to BCOA, a computational model was developed using a three-dimensional finite element program, ABAQUS, to predict the response of these structures. The model was validated with falling weight deflectometer (FWD) data from existing field sections at the Minnesota Road Research Facility (MnROAD) as well as at the University of California Pavement Research Center (UCPRC). A large database of analyses was then developed using a fractional factorial design. The database is used to develop predictive models, based on artificial neural networks (ANNs), to rapidly estimate the structural response at the joint in BCOA to environmental and traffic loads. The structural response will be related to damage using the differential energy concept. Future work includes the implementation of the developed ANNs in this study into a faulting prediction model for designing BCOA.
