DEFINITION ENGINEER: THE TERM “ENGINEER” SHALL DENOTE THE CITY PROJECT MANAGER, INSPECTOR AND/OR PLAN REVIEWER, OR THEIR DESIGNATED REPRESENTATIVE. APPLICATION THE FOLLOWING STANDARDS IN THIS SECTION SHALL BE FOLLOWED WHEN DOING TRENCH OR EXCAVATION WORK WITHIN THE PAVED PORTION OF ANY CITY OF RENTON RIGHT-OF-WAY. MODIFICATIONS OR EXEMPTIONS TO THESE STANDARDS MAY BE AUTHORIZED BY THE COMMUNITY AND ECONOMIC DEVELOPMENT ADMINISTRATOR, OR AUTHORIZED REPRESENTATIVE, UPON WRITTEN REQUEST BY THE PERMITTEE, THE PERMITTEE’S CONTRACTOR OR ENGINEER, AND DEMONSTRATION OF AN EQUIVALENT ALTERNATIVE. HOURS OF OPERATIONS HOURS FOR WORK WITHIN THE ROADWAY FOR ASPHALT OVERLAYS OR TRENCH RESTORATION SHALL BE AS DIRECTED BY THE TRAFFIC CONTROL PLAN REQUIREMENTS AND THE TRAFFIC OPERATIONS ENGINEER. INSPECTION THE ENGINEER MAY DETERMINE IN THE FIELD THAT A FULL STREET-WIDTH (EDGE-OF-PAVEMENT TO EDGE-OF-PAVEMENT) OVERLAY IS REQUIRED DUE TO CHANGES IN THE PERMIT CONDITIONS SUCH AS, BUT NOT LIMITED TO THE FOLLOWING: 1.THERE HAS BEEN DAMAGE TO THE EXISTING ASPHALT SURFACE DUE TO THE CONTRACTOR’S EQUIPMENT. 2.THE TRENCH WIDTH WAS INCREASED SIGNIFICANTLY OR THE EXISTING PAVEMENT IS UNDERMINED OR DAMAGED. 3.ANY OTHER CONSTRUCTION RELATED ACTIVITIES THAT REQUIRE ADDITIONAL PAVEMENT RESTORATION.

THE TOP TWO INCHES (2") OF ASPHALT SHALL BE GROUND DOWN TO A MINIMUM DISTANCE OF ONE FOOT (1') BEYOND THE ACTUAL OUTSIDE EDGES OF THE TRENCH AND SHALL BE REPLACED WITH TWO INCHES (2") OF CLASS B ASPHALT, PER CITY OF RENTON STANDARD PLANS. AT THE DISCRETION OF THE ENGINEER, A FULL STREET WIDTH OVERLAY MAY BE REQUIRED. LANE-WIDTH OR A FULL STREET-WIDTH OVERLAY WILL BE DETERMINED BASED UPON THE LOCATION AND LENGTH OF THE PROPOSED TRENCH WITHIN THE ROADWAY CROSS-SECTION. CHANGES IN FIELD CONDITIONS MAY WARRANT IMPLEMENTATION OF ADDITIONAL OVERLAY REQUIREMENTS. a.TRENCHES (ROAD CROSSINGS): (1)THE MINIMUM WIDTH OF A TRANSVERSE PATCH (ROAD CROSSING) SHALL BE SIX AND ONE-HALF FEET (6.5'). SEE CITY OF RENTON STANDARD PLANS. (2)ANY AFFECTED LANE WILL BE GROUND DOWN TWO INCHES (2") AND PAVED FOR THE ENTIRE WIDTH OF THE LANE.

(4)IF THE TRENCHING IS GREATER THAN OR EQUAL TO 30% OF LANE PER BLOCK (660 FOOT MAXIMUM BLOCK LENGTH), OR IF THE TOTAL PATCHES EXCEED 12 PER BLOCK, THEN THE LANES AFFECTED WILL BE OVERLAID. MINIMUM OVERLAY SHALL INCLUDE ALL PATCHES WITHIN THE BLOCK SECTION. (5)THE ENTIRE TRAVELED LANE WIDTH FOR THE LENGTH OF THE TRENCH AND AN ADDITIONAL TEN FEET (10′) AT EACH END OF THE TRENCH WILL BE GROUND DOWN TO A DEPTH OF TWO INCHES (2′′). A TWO-INCH (2′′) OVERLAY OF CLASS B WILL BE APPLIED PER CITY STANDARDS. c.POTHOLING: POTHOLING SHALL MEET THE SAME REQUIREMENTS AS TRENCHING AND PAVEMENT RESTORATION. POTHOLING SHALL BE A MINIMUM OF ONE FOOT (1') BEYOND THE EXCAVATION. ALL AFFECTED LANES WILL BE GROUND DOWN TO A DEPTH OF TWO INCHES (2") AND PAVED NOT LESS THAN SIX AND ONE HALF FEET (6.5') WIDE FOR THE ENTIRE WIDTH OF THE LANE.

RESTORATION REQUIREMENTS UTILIZING VACTOR EQUIPMENT WILL BE DETERMINED BY THE ENGINEER. 4.PAVEMENT REMOVAL IN LIEU OF GRINDING: THE CONTRACTOR IN ALL CASES CAN REMOVE THE PAVEMENT IN THE REPLACEMENT AREA INSTEAD OF GRINDING OUT THE SPECIFIED TWO INCHES (2") OF ASPHALT. FULL PAVEMENT REPLACEMENT TO MEET OR EXCEED THE EXISTING PAVEMENT DEPTH WILL BE REQUIRED FOR THE AREA OF PAVEMENT REMOVAL. PATCHING OF PERVIOUS CONCRETE SHALL FOLLOW AMERICAN CONCRETE INSTITUTE (ACI) 522.1-13. POROUS ASPHALT SHALL BE SPECIFIED ON A PROJECT-BY-PROJECT BASIS BY THE ENGINEER. PERMEABLE MATERIALS SHOULD BE REPLACED IN-KIND WHERE FEASIBLE. PATCHING POROUS ASPHALT WITH CONVENTIONAL ASPHALT IS ACCEPTABLE IF IT IS NO MORE THAN TEN PERCENT (10%) OF THE TOTAL FACILITY AREA OR DOES NOT IMPACT THE OVERALL FACILITY FUNCTION. APPROPRIATE PRECAUTIONS SHALL BE TAKEN DURING PAVEMENT REPAIR AND REPLACEMENT EFFORTS TO PREVENT CLOGGING OF ADJACENT SURFACES. 5.TRENCH BACKFILL AND RESTORATION CONSTRUCTION REQUIREMENTS: a.TRENCH RESTORATION SHALL BE EITHER BY A PATCH OR OVERLAY METHOD, AS REQUIRED AND INDICATED ON CITY OF RENTON STANDARD PLANS. b.ALL TRENCH AND PAVEMENT CUTS, WHICH WILL NOT BE OVERLAID, SHALL BE MADE BY SAWCUT OR GRINDING.

IN THE TOP SIX FEET (6') OF ANY TRENCH, BACKFILL COMPACTION SHALL BE PERFORMED IN EIGHT (8) TO TWELVE-INCH (12") LIFTS. ANY TRENCH DEEPER THAN SIX FEET (6') MAY BE COMPACTED INTWENTY-FOUR INCH (24") LIFTS, UP TO THE TOP SIX-FOOT (6') ZONE. ALL TRENCH BACKFILL SHALL BE FIRM AND UNYIELDING BUT IN NO CASE SHALL BE COMPACTED TO MORE THAN NINETY-TWO PERCENT (92%) OF MAXIMUM DENSITY IN PERMEABLE PAVEMENT AREAS. f.ALL COMPACTION SHALL BE PERFORMED BY MECHANICAL METHODS. THE COMPACTION TESTS MAY BE PERFORMED IN FOUR-FOOT (4') VERTICAL INCREMENTS MAXIMUM. THE TEST RESULTS SHALL BE GIVEN TO THE ENGINEER FOR REVIEW AND APPROVAL PRIOR TO PAVING. THE NUMBER AND LOCATION OF TESTS REQUIRED SHALL BE DETERMINED BY THE ENGINEER. d.TEMPORARY RESTORATION OF TRENCHES FOR OVERNIGHT USE SHALL BE ACCOMPLISHED BY USING MC MIX (COLD MIX), ASPHALT TREATED BASE (ATB), OR STEEL PLATES, AS APPROVED BY THE ENGINEER. ATB USED FOR TEMPORARY RESTORATION MAY BE DUMPED DIRECTLY INTO THE TRENCH, BLADED OUT AND ROLLED. AFTER ROLLING, THE TRENCH MUST BE FILLED FLUSH WITH ASPHALT TO PROVIDE A SMOOTH RIDING SURFACE. IF THE TEMPORARY TRENCH RESTORATION DOES NOT HOLD UP, THE CONTRACTOR SHALL REPAIR THE PATCH WITHIN EIGHT HOURS OF BEING NOTIFIED OF THE PROBLEM BY THE CITY. THIS REQUIREMENT APPLIES 24 HOURS PER DAY, SEVEN DAYS PER WEEK. IN THE EVENT THAT THE CITY DETERMINES TO REPAIR THE TEMPORARY PATCH, THE CONTRACTOR SHALL REIMBURSE THE CITY IN AN AMOUNT THAT IS DOUBLE THE CITY’S COSTS IN REPAIRING THE PATCH, WITH THE SECOND HALF OF THE REIMBURSEMENT TO REPRESENT CITY OVERHEAD AND HIDDEN COSTS. e.ASPHALT CONCRETE CLASS E OR CLASS B SHALL BE PLACED TO THE COMPACTED DEPTH AS REQUIRED AND INDICATED ON CITY OF RENTON STANDARD PLANS OR AS DIRECTED BY THE ENGINEER. THE GRADE OF ASPHALT SHALL BE AR-4000W. THE MATERIALS SHALL BE MADE IN CONFORMANCE WITH SECTION 9-02.1(4) OF THE STANDARD SPECIFICATIONS. f.TACK COAT SHALL BE APPLIED TO THE EXISTING PAVEMENT AT EDGE OF SAW CUTS AND SHALL BE EMULSIFIED ASPHALT GRADE CSS-1, AS SPECIFIED IN SECTION 9-02.1(6) OF THE STANDARD SPECIFICATIONS. TACK SHALL BE APPLIED AS SPECIFIED IN SECTION 5-04 OF THE STANDARD SPECIFICATIONS. g.ASPHALT CONCRETE CLASS E OR CLASS B SHALL BE PLACED IN ACCORDANCE WITH SECTION 5-04 OF THE STANDARD SPECIFICATIONS; EXCEPT THOSE LONGITUDINAL JOINTS BETWEEN SUCCESSIVE LAYERS OF ASPHALT CONCRETE SHALL BE DISPLACED LATERALLY A MINIMUM OF TWELVE INCHES (12"), UNLESS OTHERWISE APPROVED BY THE ENGINEER. FINE AND COARSE AGGREGATE SHALL BE IN ACCORDANCE WITH SECTION 9-03.8 OF THE STANDARD SPECIFICATIONS.ALL STREET SURFACES, WALKS OR DRIVEWAYS WITHIN THE STREET TRENCHING AREAS SHALL BE FEATHERED AND SHIMMED TO AN EXTENT THAT PROVIDES A SMOOTH-RIDING CONNECTION AND EXPEDITIOUS DRAINAGE FLOW FOR THE NEWLY PAVED SURFACE. FEATHERING AND SHIMMING SHALL NOT DECREASE THE MINIMUM VERTICAL CURB DEPTH BELOW FOUR INCHES (4") FOR STORM WATER FLOW. THE ENGINEER MAY REQUIRE ADDITIONAL GRINDING TO INCREASE THE CURB DEPTH AVAILABLE FOR STORM WATER FLOW IN AREAS THAT ARE INADEQUATE. SHIMMING AND FEATHERING AS REQUIRED BY THE ENGINEER SHALL BE ACCOMPLISHED BY RAKING OUT THE OVERSIZED AGGREGATES FROM THE CLASS B MIX AS APPROPRIATE. SURFACE SMOOTHNESS SHALL BE PER SECTION 5-04.3(13) OF THE STANDARD SPECIFICATIONS. THE PAVING SHALL BE CORRECTED BY REMOVAL AND REPAVING OF THE TRENCH ONLY. ASPHALT PATCH DEPTHS WILL VARY BASED UPON THE STREETS BEING TRENCHED. THE ACTUAL DEPTHS OF ASPHALT AND THE WORK TO BE PERFORMED SHALL BE AS REQUIRED AND INDICATED ON CITY OF RENTON STANDARD PLANS. COMPACTION OF ALL LIFTS OF ASPHALT SHALL BE A MINIMUM NINETY-TWO PERCENT (92%) OF DENSITY AS DETERMINED BY WSDOT TEST METHOD 705. THE NUMBER OF TESTS REQUIRED SHALL BE DETERMINED BY THE ENGINEER. TESTING SHALL BE PERFORMED BY AN INDEPENDENT TESTING LAB WITH THE RESULTS BEING SUPPLIED TO THE ENGINEER.
