• Abstract:
  This report discusses a method of constructing an embankment over marshland soils by end-dumping reef shell directly onto the marshland with no other major subgrade preparation. The dumped reef shell is then spread out to form a "floating" embankment over the soft marshland. This report compares the subsidence characteristics of a reef shell embankment with those of a clam shell embankment and determines if such a reef shell embankment would provide adequate structural support for traffic. The report indicates it is physically and economically feasible to construct a reef shell embankment on soft organic marshland soils. A properly constructed reef shell embankment develops into a homogeneous floating slab of substantial stability and strength capable of supporting allowable traffic loads.
