Webvertical load. 6.3 Dead Load – Additional Dead Loads (DW) No DW loads are included in the culvert design since BOXCAR does not account for the pavement weight separately from the earth fill over the culvert. The fill depth measurement used by BOXCAR includes the pavement thickness so only the difference in pavement and soil WebDec 26, 2024 · This study examined the dynamic load allowance ( IM) of culverts with span lengths between 3 and 7.7 m and fill depths between 0 and 0.5 m. All road surfaces were in good condition. The IM for each truck pass was determined by taking the ratio of dynamic strain to static strain at the location of maximum static strain.
