<br />PGSF WMVD Storm and Combined Sewer - Construction Package 2 Surface Restoration <br />Project No. 180162 32 10 00 - 4 <br /> <br />B. Contractor shall demolish and replace in kind full panels cut or damaged in the <br />performance of the Work. Saw cut excavation limits and replacement sections. <br />1. Cement Concrete Panel Joints and transitions shall conform to WSDOT Standard Plan <br />A-10.10-04 <br />2. Streets which have cement concrete pavements surfaced with asphalt concrete shall <br />be patched as shown on Standard Drawing 326. <br />3. HMA plant mix shall not be placed until three days after the cement concrete base <br />has been placed or otherwise permitted by the Construction Manager. <br />4. The HMA plant mix shall not be placed until the concrete base has received a tack <br />coat of CRS-2 at a rate of 0.12 to 0.20-gallons per square yard. <br />a. The edges of the existing asphalt and castings shall also be painted with the tack <br />coat. The HMA pavement shall then be placed, leveled, and compacted to <br />conform to the surface of the existing HMA. Immediately thereafter, all joints <br />between the new and original asphalt pavement shall be painted with CSS-1 <br />asphalt emulsion and covered with dry sand before the asphalt solidifies <br />b. Asphalt shall be compacted to 92-percent of maximum density as determined by <br />WSDOT Test Method 705. <br />2.06 UNTREATED ROADWAY SURFACES <br />A. Existing crushed rock, gravel, and oil mat streets shall be restored with Crushed <br />Surfacing Top Course to a compacted depth of four inches within the neat lines of the <br />trench. Crushed surfacing shall be mixed, placed, spread and shaped in accordance with <br />the requirements of COE Section 4-04. <br />2.07 INCIDENTAL PAVEMENT PATCHING <br />A. Incidental pavement patching shall be done only at the direction of the Engineer for <br />patching and restoring areas between the back of new sidewalks and adjacent asphalt <br />driveways, paving ramps at the ends of sidewalks, and gutters that are adjusted to grade. <br />B. Asphalt for incidental pavement patching shall be HMA CL 1/2”, PG 64-22. <br />2.08 PORT OF EVERETT MATERIAL TESTING REQUIREMENTS <br />A. Import material shall be sampled and tested under the oversight of a qualified licensed <br />environmental professional (i.e., licensed engineer, geologist, or hydrogeologist), at a rate <br />of five samples for the first 1,000 cubic yards of imported material, and one sample for <br />each additional 1,000 cubic yards to verify that the material meets import fill criteria. The <br />Contractor shall provide the Import Chemical Testing Results Submittal to the Engineer <br />for review and approval in consultation with the Department of Ecology. Once the <br />material has gained approval from the Engineer and the Port of Everett, the material may <br />be transported to the Site. Whenever the source or stockpile from which the imported fill <br />materials are obtained is changed, the initial rate of sampling starts over at five samples <br />for the first 1,000 cubic yards. The gradation and moisture-density testing of all imported <br />materials shall be sampled and tested at a rate of one sample per 1,000 truck cubic <br />yards to verify that the material is in conformance with the project requirements. Once it <br />has passed this verification, the material may be transported to the Site. Imported <br />materials delivered to the site that are not in conformance with the project requirements <br />shall be removed by the Contractor his sole expense.
