Before spreading any material for the upper courses, allow t <br />Engineer to make density tests for the lower courses to determine <br />required compaction has been obtained. After spreading the mate <br />top course, scarify finish and shape its surface to produce the req <br />and cross-section, free of scabs and laminations, after compaction. <br />Moisture Content: When the material does not have the proper moisture <br />ensure the required density, wet or dry it as required. When adding water <br />mix it in to the full depth of the course that is being compacted. During w: <br />drying operations, manipulate, as a unit, the entire width and depth of the <br />that is being compacted. <br />Density Requirements: Compact the material to a density of not Tess than <br />maximum density as determined by FM 1-T 180. Where the width of the <br />construction is not sufficient to permit use of standard base compaction <br />perform compaction using vibratory compactors, trench rollers, or other s <br />equipment which will provide the density requirements specified herein. <br />be added to the asphalt material as needed to obtain the proper compact <br />Density Tests: Meet the requirements of 200-7 with the exception of 200 - <br />Within the entire limits of the width and depth of the base, obtain a minim <br />density in any LOT of 98% of the maximum density as determined by FM <br />Testing Surface: Test the surface in accordance with the requirements of <br />b) <br />or <br />t without <br />special <br />placing <br />• <br />ts, <br />of 120- <br />ly areas, <br />xcept <br />200-7.2. <br />n shape <br />f scabs <br />n blade <br />finished <br />e <br />hat the <br />ial for the <br />ired grade <br />ontent to <br />uniformly <br />tting or <br />course <br />1 <br />98% of <br />ase <br />•uipment, <br />ecial <br />ater may <br />on. <br />.2.1. <br />m <br />1-T 180. <br />200-7.3.1. <br />Asphalt millings shall be applied with a wetting agent in two lifts not to exceed 6' per lift <br />and compacted to provide a smooth travel surface. <br />Item of Payment <br />Bid Item No. 283-1 — Asphalt Millings (8" Thick) (Two Lifts) — Per Square and <br />Bid Item No. 283-1A — Asphalt Millings (6" Thick) (Driveways) — Per Squ-re Yard <br />01025-16 Technical Specifi, <br />P•\Pnhlir \A//Irks\F J(INFPRIM(z, fll\/ISIrm PRCI.IFC:TS\1314-107th Ava Millinn 90th St to 94th St\Admin\hid documents <br />ations <br />Master Contract <br />
