TRB’s Transportation Research Record: Journal of the Transportation Research Board, 2045 includes 12 papers that explore implementing intelligent compaction specifications, in situ tests for compaction control of a bottom ash embankment, evaluation of in situ density and moisture content by using elastic and electromagnetic wave propagation, compaction-induced earth pressures against a sheet pile wall in peat, and resistance factors for axially loaded concrete piles driven into soft soils. This issue of the TRR also examines flowfill and mechanically stabilized earth bridge approaches, resistance factors for drilled shafts in weak rock, analysis of 3-m-diameter induced trench culvert under a 19.4-m soil cover, long-term performance of pavement drainage layers, wrapped-face mechanically stabilized earth walls with inadequate compaction near facing, geocell-reinforced sand behavior under a vertical load, and geogrid in flexible pavements.
