TRB’s Transportation Research Record: Journal of the Transportation Research Board, No. 2305 consists of 18 papers concerned with the design of flexible and rigid pavements. Specific topics discussed with regard to rigid pavements include warping and drying shrinkage models; Mechanistic-Empirical Pavement Design Guide (MEPDG) procedure for two-lift composite concrete pavements; temperature gradients for ultrathin bonded concrete overlays on asphalt pavements; mechanistic-empirical continuously reinforced concrete pavement (CRCP) design approach with modified punchout models; concrete slab curling effects on joint load transfer responses; concrete pavement joint diagnostics using ultrasonic tomography; CRCP terminal anchorages to protect bridge structures; and joint load transfer for jointed precast concrete pavements.
Papers in this issue of TRR that address flexible pavements include mechanistic-empirical design procedures for fully permeable pavement; induction healing of porous asphalt; structural coefficient of open-graded friction courses; implications of climate change for flexible pavement design and performance; reliability-based mechanistic-empirical pavement design statistical methods; calibrating the MEPDG for North Carolina; design thicknesses for flexible airfield pavement; loading frequency for linear elastic analysis of asphalt pavements; load and resistance factors and design parameter offsets for the MEPDG; and streamlining the MEPDG.
