HOURS OF OPERATIONS
HOURS FOR WORK WITHIN THE ROADWAY FOR ASPHALT OVERLAYS OR TRENCH RESTORATION SHALLBE 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 TOEDGE-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.
CITY OF RENTON STANDARDS
ALL MATERIALS AND WORKMANSHIP SHALL BE IN ACCORDANCE WITH THE CITY OF RENTON STANDARD
AND SUPPLEMENTAL SPECIFICATIONS(CURRENT ADOPTED VERSION) EXCEPT WHERE OTHERWISE

SITE CONDITIONS.
3.REQUIREMENT FOR PATCHING, OVERLAY, AND OVERLAY WIDTHS:
ALL TRENCH AND PAVEMENT CUTS SHALL BE MADE BY SAWCUT OR BY GRINDING. SAWCUTS OR
GRINDING SHALL BE A MINIMUM OF ONE FOOT (1') OUTSIDE THE TRENCH WIDTH. 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 LOCATIONAND 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 ANDONE-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.
(3)THE PATCH SHALL BE A MINIMUM OF ONE FOOT (1') BEYOND THE EXCAVATION AND PATCHLENGTH SHALL BE A MINIMUM OF AN ENTIRE TRAVELED LANE.
(4)IF THE OUTSIDE OF THE TRENCHING IS WITHIN THREE FEET (3') OF ANY ADJACENT LANE LINE,
THE ENTIRE ADJACENT TRAVELED LANE AFFECTED WILL BE REPAVED.
(5)AN AREA INCLUDING THE TRENCH AND ONE FOOT (1') ON EACH SIDE OF THE TRENCH BUT
NOT LESS THAN SIX AND ONEHALF FEET (6.5') TOTAL FOR THE ENTIRE WIDTH OF THEAFFECTED TRAVELED LANES WILL BE GROUND DOWN TO A DEPTH OF TWO INCHES (2"). A
TWO-INCH (2") OVERLAY OF CLASS B ASPHALT WILL BE APPLIED PER CITY STANDARDS.

d.IF THE EXISTING MATERIAL (OR OTHER MATERIAL) IS DETERMINED BY THE ENGINEER TO BE
SUITABLE FOR BACKFILL, THE CONTRACTOR MAY USE THE NATIVE MATERIAL EXCEPT THAT THE
TOP SIX INCHES (6") SHALL BE CRUSHED SURFACING TOP COURSE MATERIAL.
e.THE TRENCH SHALL BE COMPACTED TO A MINIMUM NINETY-FIVE PERCENT (95%) DENSITY, AS
DESCRIBED IN SECTION 2- 03 OF THE STANDARD SPECIFICATIONS. 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. THENUMBER 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

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 BMIX 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 BEINGTRENCHED. 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 ASDETERMINED 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. TESTING IS NOTINTENDED TO RELIEVE THE CONTRACTOR FROM ANY LIABILITY FOR THE TRENCH
RESTORATION. IT IS INTENDED TO SHOW THE INSPECTOR, AND THE CITY, THAT THE
RESTORATION MEETS THESE SPECIFICATIONS.
h.ALL JOINTS, EXCEPT THOSE ASSOCIATED WITH PERMEABLE PAVEMENT, SHALL BE SEALED
USING PAVING ASPHALT AR4000W.
