Dowel is a tool that is used to connect the slab by slab, slab concrete with asphalt pavement, which serves to lock the plate edges and reduce the occurrence of crack between the concrete.
- First type is dowel bar connection. This dowel has two types of connections made from a plain which is made of steel dowel connections and the connection end of the dowel. Dowel connections installed in the middle of slab concrete, while the connection is installed at the edge of the dowel end slab concrete. The difference between them lies in the length of anti-rust coating.
- Second type is dowel with a tie bar which serves to lock the top edge slab concrete (end). The dowel is using steel threaded connections without grease.
- Third type is dowel with the crack inducer that functions to reduce the occurrence of cracks in slab concrete and between slab concrete.
- Fourth type is dowel as expansion joint.
- Fifth type is connection with the thickening of the edge of the tie bar. This connection is used on the plate with the transition between the concrete pavement with asphalt pavement.
