I have project that has a longitudinal crack in the PT slab The crack runs along a single curved strand line near the longitudinal center of the rectungular slab (280'x100'). The crack is <1/16" wide and is not vertically offset. The crack runs the entire width of the slab and.
The slab is ~10" thick and contains regularly spaced strands which span the longintudinal direction (16k/ft) and curved bulk strands along the column lines in the transverse direction (~425 k) A drive lane and parking area are located above with no unusual loading near the crack line.
Any thoughts as to the source of the cracking? Is it better to repair with an elastic sealant or rigid epoxy?
