D. Embankment - General Requirements for Embankment Materials: The following is added after the first paragraph of Subarticle 120-7.2: Roadway Design Standard Index No. 505, Embankment Utilization Details is modified by the addition of the following: Any stratum or stockpile or soil which contains obvious pockets of highly organic material may be designated as muck or unsuitable for construction of subgrade by the Owner. Backfill material containing more than 2.0% by weight of organic material, as determined by FM 1-T 267 and by averaging the test results for three randomly selected samples from each stratum or stockpile of a particular material, shall not be used in construction of the reinforced volume. If an individual test value of the three samples exceeds 3.0%, the stratum or stockpile will not be suitable for construction of the reinforced volume. No A-8 material permitted in embankment. E. Payment shall be made under: Bid Item No. 6 — Earthwork (To Include Excavation, Embankment, and Grading) — Per Lump Sum SECTION -160 - STABILIZING A. Section 160 is modified by the addition of the following: "The stabilization thickness indicated on plans shall be considered a minimum thickness. Thickness will vary to conform to the lines, and grades shown in the plans." Minimum L.B.R. = 40 - No under -tolerance. B. Payment shall be made under: Bid Item No. 7 - Type B Stabilization LBR40 (6") - Per Square Yard SECTION - 283 — RECLAIMED ASPHALT PAVEMENT BASE A. Description Construct a base course composed of reclaimed asphalt pavement (RAP) material. Use RAP material as a base course only on non -limited access paved shoulders, shared use paths, or other non -traffic bearing applications. B. Materials Obtain the RAP material by either milling or crushing an existing asphalt pavement. Material that passes a 5/8" sieve and is graded uniformly down to dust shall be used. The following procedure will be used for approval: 1. Conduct a minimum of six extraction gradation analyses of the RAP material. Take samples at random locations in the stockpile. The average asphalt cement content of the six stockpile samples must be 4% or greater with no individual result below 3- 1/2%. 2. Request the Engineer to make a visual inspection of the stockpile of RAP material. Based on this visual inspection of the stockpiled material and the results of the 01025-25 Technical Specifications F:\Public Works\ENGINEERING DIVISION PROJECTS\1413-Martin Luther King Walking Trail\Admin\bid documents\Master Contract Documents\Technical Specifications.doc
