(A) All joints shall be constructed as per App. C of this chapter.
(B) Longitudinal and transverse joints shall be constructed as shown on the plans and construction joints wherever construction may require them.
(C) Longitudinal joints are those joints parallel to the lane of construction. They may be either intermediate center joints or the construction joints between construction lanes.
(D) Expansion joints may be only transverse. They are used only where specifically shown on the plans.
(E) Transverse joints shall be contraction, expansion or construction joints.
(F) The edges of the pavement and those joints where such edging is shown on the plans shall be rounded with an edger having a radius of one-eighth inch. Transverse joints shall be continuous across the entire paved area, including the curb.
(1) Expansion joints.
(a) Expansion joints, where shown on the plans, shall conform to the specifications in App. A, § 2(B)(1), of these regulations. They shall extend the entire width of the pavement. They shall be of the dimensions and spacing as shown on the plans. The filler shall be held accurately in place during the placing and finishing of the concrete by a bulkhead, a metal channel cap or other approved method. Expansion joints shall be located in pavement sections entering a curve at the PC and PT, at all street intersections at the point of curvature of the turning radii entering the intersection and at cul-de-sacs or turn-arounds at the point of curvature of the first turning radii approaching the turn-around.
(b) Under no circumstances shall any concrete be left above the expansion material or across the joint at any point. Any concrete spanning the ends of the joint next to the forms shall be carefully cut away after the forms are removed.
(c) Before the pavement is opened to traffic, the groove above the filler shall be cleaned and sealed with specified joint sealing material covered under App. A, § 2(B)(2), of these regulations.
(2) Transverse joints.
(a) Transverse contraction joints shall be of sawed, formed dummy groove or premolded strip type. All transverse joints shall be one-fourth of the pavement thickness.
(b) The spacing of undoweled contraction joints shall be specified by the design engineer and shall be based on accurate performance records from streets in service. In no case shall the contraction joints be spaced at intervals greater than 20 feet.
(c) If sawed joints are specified on the plans, they shall be sawed early enough to control cracking, but late enough to prevent any damage by blade action in the slab surface and to the concrete immediately adjacent to the joints.
(3) Construction joints. Transverse construction joints of the type shown on the plans shall be placed wherever the placing of concrete is suspended for more than 30 minutes. A transverse construction joint with smooth bars shall be used if the joint occurs at the location of a contraction joint. Deformed tie bars are used if the joint occurs at any other locations.
(4) Longitudinal joints. Longitudinal joints shall be placed as shown on the plans. They shall be of the sawed, dummy groove, premolded strip of tied construction type. All longitudinal sawed joints shall conform to App. A, § 10(F)(2), of these regulations. Joints between construction lanes shall be the tied construction type. The depth of longitudinal joints, except for construction joints, shall be at least one-fourth of the pavement thickness. They shall coincide with lane markings wherever possible and shall be provided between each traffic lane.
(5) Integral curb joints. In the construction of transverse joints of concrete integral curb pavement, special care must be taken to see that all transverse joints extend continuously through the pavement and curb, except tied transverse construction joints.
