BE AS DIRECTED BY THE TRAFFIC CONTROL PLAN REQUIREMENTS AND THE TRAFFIC OPERATIONS C.
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 4.
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

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.

ANY TRENCHING OVER FOUR FEET (4') IN DEPTH MAY USE MATERIALS APPROVED BY THE
ENGINEER OR MATERIALS LAB FOR BACKFILLING BELOW THE FOUR -FOOT (4') DEPTH.
IF THE EXISTING MATERIAL PR OTHER MATERIAL) IS DETERMINED BY THE ENGINEER TO BE
SUITABLE FOR BACKFILL, TH CONTRACTOR MAY USE THE NATIVE MATERIAL EXCEPT THAT THE
TOP SIX INCHES (6") SHALL BE CRUSHED SURFACING TOP COURSE MATERIAL.
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.
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.
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

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. TESTING IS NOT
INTENDED 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.
I. WHEN TRENCHING WITHIN THE UNPAVED ROADWAY SHOULDER(S), THE SHOULDER SHALL BE
RESTORED TO ITS ORIGINAL CONDITION, OR BETTER.
j. THE FINAL PATCH SHALL BE COMPLETED AS SOON AS POSSIBLE AND SHALL NOT EXCEED
FIFTEEN 15) WORKING DAYS AFTER FIRST OPENING THE TRENCH. THIS TIME FRAME MAY BE
ADJUSTED IF DELAYS ARE DUE TO INCLEMENT PAVING WEATHER OR OTHER ADVERSE
CONDITIONS THAT MAY EXIST. HOWEVER, DELAYING OF FINAL PATCH OR OVERLAY WORK IS
SUBJECT TO THE ENGINEER'S APPROVAL. THE ENGINEER MAY DEEM IT NECESSARY TO
COMPLETE THE WORK WITHIN THE FIFTEEN (15) WORKING DAY TIME FRAME AND NOT ALLOW
ANY TIME EXTENSION. SHOULD THIS OCCU , THE CONTRACTOR SHALL PERFORM THE
NECESSARY WORK, AS DIRECTED BY THE ENGINEER.
k. A CITY OF RENTON TEMPORARY TRAFFIC CONTROL PLAN (FROM RENTON TRANSPORTATION
ENGINEERING) SHALL BE SUBMITTED AND APPROVED BY THE ENGINEER A MINIMUM OF THREE
(3) WORKING DAYS PRIOR TO COMMENCEMENT OF WORK.
6. REMOVAL OF UTILITY LOCATE MARKINGS FROM SIDEWALKS REQUIRED:
