Backfill material containing more than 2.0% by weight of organic material, as <br />determined by FM 1-T 267 and by averaging the test results for three randomly <br />selected samples from each stratum or stockpile of a particular material, shall not be <br />used in construction of the reinforced volume. If an individual test value of the three <br />samples exceeds 3.0%, the stratum or stockpile will not be suitable for construction of <br />the reinforced volume. <br />No A-8 material permitted in embankment. <br />E. Payment shall be made under: <br />Bid Item No. 120-1 — Excavation, Regular (Roadway) — Per Lump Sum <br />Bid Item No. 120-6 - Embankment (Compacted in Place) - Per Lump Sum <br />SECTION -160 - STABILIZATION <br />A. Section 160 is modified by the addition of the following: <br />"The stabilization thickness indicated on plans shall be considered a minimum <br />thickness. Thickness will vary to conform to the lines, and grades shown in the plans." <br />Minimum L.B.R. = 40 - No under -tolerance. <br />B. Payment shall be made under: <br />Bid Item No. 160-4 - Type B Stabilization (12" Subgrade LBR40) - Per Square Yard <br />Bid Item No. 160-4A - Type B Stabilization (6" Subgrade LBR40) (Shoulder) — Per <br />Square Yard <br />SECTION - 283 — RECLAIMED ASPHALT PAVEMENT <br />A. Description <br />Construct a base course composed of reclaimed asphalt pavement (RAP) material. Use <br />RAP material as a base course only on non -limited access paved shoulders, shared use <br />paths, or other non -traffic bearing applications. <br />B. Materials <br />Obtain the RAP material by either milling or crushing an existing asphalt pavement. Use <br />material so that 100% passes a 1" sieve and at least 97% (by weight) pass a 3/ inch sieve <br />and is graded uniformly down to dust. <br />The following procedure will be used for approval: <br />1. Conduct a minimum of six extraction gradation analyses of the RAP material. Take <br />samples at random locations in the stockpile. The average asphalt cement content <br />of the six stockpile samples must be 4% or greater with no individual result below 3- <br />1 /2%. <br />2. Request the Engineer to make a visual inspection of the stockpile of RAP material. <br />Based on this visual inspection of the stockpiled material and the results of the <br />Contractor's extraction gradation analyses, the Engineer will determine the <br />suitability of the materials. <br />3. The Engineer may require crushing of stockpiled material to meet the gradation <br />criterion. Perform all crushing before the material is placed. <br />C. Spreading RAP Material. <br />1. Method of Spreading: Spread the RAP with a blade or device which strikes off the <br />material uniformly to laying thickness and produces an even distribution of the RAP. <br />01025-15 Technical Specifications <br />F:\Public Works\ENGINEERING DIVISION PROJECTS\1317-85th St Milling_91st Ave to 101st Ave\Admin\bid documents\Master <br />Contract Documents\Technical Specifications.doc <br />
