These are provided along the transverse direction to allow the expansion and contraction of a concrete slab due to temperature and subgrade moisture variation.
They are intended to prevent potentially damaging forces accumulating within the slab itself or surrounding structures. Maximum spacing of expansion joints ranges from 25-27 m in jointed reinforced concrete slabs and from 40 m (for slabs <230 mm thick) to 60 m (for slabs >230 mm thick) in unreinforced concrete.
