Rigid pavement shall be jointed in order to control cracking. Joints shall be constructed in accordance with the type and dimensions and at the locations required by Standard Specifications, these regulations, or as directed by the Town Engineer's office.
(A) Spacing of weakened plane, transverse, or contraction joints shall not exceed 20 feet. Closer spacing to average 15 feet is encouraged. A transverse contraction joint may either be formed or sawed dummy groove, ribbon or pre-molded strip type, and shall be one-fourth the thickness of the pavement.
(B) When a transverse joint is to be formed by sawing, care must be taken to saw the grooves soon after placing the concrete to prevent the formation of cracks due to contraction of the slab.
(C) One of the above named joints shall be placed at every catch basin and manhole in the line of pavement. The location of manholes in the pavement shall determine the exact location of the joints.
(D) All joints shall extend throughout the curb to the full width of the pavement.
(E) A transverse expansion joint shall be placed at the intersections, tangent points of sharp curves, and wherever else shown on the plans.
(F) Whenever the width between forms of the pavement under construction is greater than ten feet, a longitudinal joint shall be constructed so as to divide the pavement into strips not to exceed ten feet each. This may be accomplished by sawing or by installing a slot or groove as herein described for a contraction joint.
(G) White membrane curing compound AASHTO Number 2-M-14B must be properly applied to give complete coverage immediately after finishing.
