TRB’s Transportation Research Record: Journal of the Transportation Research Board, No. 2037 includes 13 papers related to rigid and flexible pavement design. Specific topics explored that are related to rigid pavements include variation of crack width over time, mechanistic effects of dowel misalignment, environmental effects on deformation and smoothness, and fracture behavior of functionally graded concrete materials. Topics related to flexible pavements examined in this issue of the TRR include a determination of in-place hot-mix asphalt layer modulus, high-performance layered elastic analysis, determining layer thickness, Windows-based top-down cracking design tool, statewide volume adjustment factors in the "Mechanistic-Empirical Pavement Design Guide," influence of statewide axle load spectra on pavement performance, tire–pavement contact stress, in situ dielectric constant of pavement materials, and uncertainty in distress measurement for performance model calibration.
