Description <br />Construct a base course composed of reclaimed asphalt pavement (RAP) mate <br />RAP material as a base course only on non -limited access paved shoulders, sh <br />paths, or other non -traffic bearing applications. <br />B. Materials <br />Obtain the RAP material by either milling or crushing an existing asphalt pavem <br />material so that 100% passes a 1" sieve and at least 97% (by weight) pass a 3/4 <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 mat= <br />samples at random locations in the stockpile. The average asphalt ceme <br />of the six stockpile samples must be 4% or greater with no individual res <br />1/2%. <br />2. Request the Engineer to make a visual inspection of the stockpile of RA <br />Based on this visual inspection of the stockpiled material and the results <br />Contractor's extraction gradation analyses, the Engineer will determine t <br />suitability of the materials. <br />3. The Engineer may require crushing of stockpiled material to meet the gr. <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 strik <br />material uniformly to laying thickness and produces an even distribution <br />The Contractor may also place the RAP material directly from the milling <br />into the trench by a conveyor. When placing the RAP material by convey <br />from the milling machine, obtain the Engineer's approval of the milling pr <br />2.
