A method of forming a section of a roadway or floor having (i) a first concrete slab and a second concrete slab longitudinally adjacent to the first concrete slab, and (ii) a third concrete slab and a fourth concrete slab longitudinally adjacent to the third concrete slab, wherein the first concrete slab is transversely adjacent to the third concrete slab, and wherein the second concrete slab is transversely adjacent to the fourth concrete slab, said method comprising:
- positioning a concrete slab load transfer and connection apparatus on a sub-grade at the location of the roadway or floor, the concrete slab load transfer and connection apparatus including:
- (i) a plurality of load transfer dowels,
- (ii) a basket supporting the load transfer dowels, and
- (iii) a plurality of slab connection members forming part of or connected to the basket,
- wherein the positioning includes:
- (a) positioning a plurality of the load transfer dowels at a first area where a first joint will be formed between the first concrete slab and the second concrete slab, and
- (b) positioning the slab connection members at a second area where a second joint will be formed between the first concrete slab and the third concrete slab and between the second concrete slab and the fourth concrete slab, and such that one of the slab connection members will connect the first concrete slab to the third concrete slab and one of the slab connection members will connect the second concrete slab to the fourth concrete slab;
- and
- pouring the concrete for the section of the roadway or floor and creating the first and second joints.
