About this detail

Concrete slab pad dowel placement, curb reinforcement, and equipment anchorage requirements. The concrete slab surface requires roughening to a one-quarter-inch amplitude and a clean surface. Where pad dimensions in either direction are less than or equal to fifteen feet, number four dowels are placed at twelve inches on center at the perimeter and in the field; where dimensions exceed fifteen feet, dowels are placed at twelve inches at the perimeter and forty-eight inches in the field. Number four adhesive anchors with a three-and-a-half-inch embedment may be substituted for dowels at the contractor's option, requiring a pull test to 4,900 pounds. Curbs feature number four bars at twelve inches on center each way, with one inch of typical clearance and one-and-a-half-inch minimum concrete cover. Where a beam occurs below, straight bars with development length are used with number four bars on both sides typically.
