TRB’s Transportation Research Record: Journal of the Transportation Research Board, No. 2116 includes 14 papers that explore instrumented rollers to assess construction quality, vibratory roller-measured soil stiffness and resilient modulus testing, automation of pavement sublayer moisture content determination, a stiffness-based assessment of pavement foundation materials, horizontal drains for clay landslide stabilization, and high-capacity piles. This issue of the TRR also examines a geotechnical perspective on design-build contracts, high-capacity composite spun piles, laterally loaded shafts behind a mechanically stabilized earth wall, deformation factors of buried corrugated structures, geogrid reinforcement in granular materials, geogrid base reinforcement with aggregate interlock, geosynthetic-reinforced aggregate roads, and porous asphalt composites with carbon fiber reinforcement polymer grids.
