Does anyone have a railroad code (maybe AREA) that would have requirements on the frost depth for a concrete cantilevered retaining wall along the railroad tracks? The site is just south of Boston, Massachusetts.
SECTION 3.3 DEPTH OF BASE OF FOOTINGS
3.3.1 SELECTION OF TENTATIVE DEPTHS (1995)
On the basis of the data concerning the subsurface materials, tentative elevations for the bases of the footing should be selected. Unless special provisions are made, the depth shall not be less than the depth of frost
penetration, scour, or, in expansive clay subsoils, less than the thickness of the zone of significant volume
change of the subsoil due to seasonal moisture variations. Footings should be placed below disturbed shallow
soils, uncontrolled fills, collapse susceptible soils, and organic soils.
The AREMA Manual is not available on-line. AREMA charges big bucks for the Manual. I think it costs over $300.00 for AREMA members, over $400.00 for non-members.
