Combined curb and gutter also called curb and channel has a concrete curb and gutter cast together in one piece. For curb gutter and curb gutter provide contraction joints at 10 centers max. Contraction joints adjacent to concrete pavement on tangents and flat curves are to match the pavement joints with intermediate joints not to exceed 10 centers.

To function correctly curb and gutter should always be downslope from the pavement surface so the surface runoff from the pavement will drain into the gutter. 6 tie bars spaced 2 6 c c installed perpendicular to the longitudinal joint maximum drill hole size is 1 8 greater than tie bar diameter 1 contraction joint 6 0 min. Integral curb is curbing constructed integrally as a part of a concrete pavement. New curb and gutter surface drains concrete pavement or other new concrete.

For pcc pavements match the gutter depth to the depth of adjacent pcc pavement 6. For hot bituminous pavement use 7 gutter depth as shown. With the manufacturer s recommendations. Most curb is constructed separately from the pavement and the gutter is formed at the joint between the roadway and the curb.

As water is the biggest enemy of any pavement these dry curbs will result in poor pavement performance and shorter pavement life. Tie curb and gutter to abutting pcc pavement with no.
