Longitudinal Cracking Structural Model
This document reviews the derivation of the structural models for longitudinal cracking in 6'x6' slabs. The longitudinal cracking failure mode was determined to be the critical failure mode for these slabs, based on observed distresses and supported by a computational analysis.

Climactic Considerations
This document explains, in-depth, the theory on how climatic effects were accounted for within the BCOA-ME. Both the effect of temperature on the stiffness of the hot mix asphalt and the effect of temperature gradients that develop in the overlay are incorporated in the design process.

Debonding Models
This document characterizes the bond between the concrete overlay and the existing asphalt structure. Small scale and full scale laboratory testing was performed to determine the fracture mechanics properties of the bond between the concrete and the asphalt and to validate debonding models.

Identifying Failure Modes of slabs with 1.8 m x 1.8 m (6 ft x 6 ft) Joint Spacing
This paper identifies a longitudinal crack in the wheel path as the predominant failure mechanism in BCOA with joint spacing of 1.8 m x 1.8 m (6 ft x 6 ft). This paper was published in the Transportation Research Record: The Journal of the Transportation Research Board.
