Utility Construction and Use of the Right-of-Way Policies and Procedures Manual Page 13 <br /> In monolithic curb and gutter concrete streets, a new joint shall be allowed up to 18” from the face <br />of the curb to leave the “gutter” intact. On streets with bike lanes, cut location shall be determined <br />by the Utility Inspector. <br /> Fully reinforce any cut repair where the repair length to width ratio exceeds 1.5:1. <br /> Trench cuts shall be square with the edges of the panel (no diagonal cuts). <br /> Construct Asphalt to Concrete Transition panel where PCC connects to AC (See DET1601(A)). <br /> Match joint locations in cut repair with existing joint locations. <br /> Dowels and rebar reinforcement shall be required on all concrete placed in the street and shall <br />comply with the Standard Specifications and drawing DET 1600 & DET 1601. <br /> When required by the Utility Inspector the designer shall provide a jointing plan. The jointing <br />plan shall comply with City Standard Specifications and industry best practices (See Portland <br />Cement Association for Examples). <br /> Utility trenches patched with PCC shall be kept free of traffic or other detrimental trespasses <br />through use of suitable barriers and other traffic control devices for a minimum period of 7 days <br />or the point at which it reaches a minimum strength of 3000 psi. An alternative using 9.0 sacks of <br />Portland cement per cubic yard of concrete allows the traffic to be returned after a minimum period <br />of 3 days. In no case shall vehicle trespass occur on PCC streets until the PCC reaches a strength <br />of at least 3000 psi. When an early street opening, less than (7) seven days, is desired furnish Class <br />4000 – 1 concrete with admixture to accelerate the strength to at least 3000 psi in 7 days. The use <br />of high early strength concrete may be necessary when early opening to traffic is required. Work <br />shall also comply with City Standard Specifications Section 00754. <br /> Where PCC overlaid by asphalt concrete is encountered, the pavement in the trench cut shall be <br />replaced with PCC overlaid with AC to match existing, but the combined thickness shall not be <br />less than 7” for Local streets, 9” for Collectors and 10” for Arterial streets. <br /> The permittee shall notify the Utility Inspector at least 1 full business day before any permanent <br />surface restoration is to be made by the permittee's own staff or that of contractor working for the <br />permittee. <br /> The permittee shall notify the Utility Inspector in writing no more than 2 business days after final <br />restoration has concluded. <br /> The permittee shall be responsible for maintaining trench cuts and/or panel replacements until such <br />time as the road is resurfaced or fully reconstructed and will be required to repair damage from <br />trench cuts and/or panel replacement settlement indefinitely. <br /> <br />3.03.3 Street Cuts and restoration - Asphalt Cement Concrete Pavement <br /> See Section 3.04.1 to obtain approval for trench cuts on streets with a paved surface less than 5 <br />years old.
