This base course is then paved over with an HMA surface course. Full depth reclamation (FDR). FDR is a form of CIPR in which the entire pavement structure is pulverized and recycled. Typically some form of BST or HMA overlay is placed on top of the recycled material.
The polymerized HMA Surface Course, IL 9.5 FG, Mix "D", N90 summary of quantities on page 3 is 1067 TN. The paving schedule on page 6 shows the quantity is 1067 SY. It appears that the 1067 SY quantity is correct which would mean the 1067 TN quantity would be considerably less. Asphalt Leveling Course - Benchmark Inc. May 22, 2018 Evaluation of HMA Modified with Recycled Asphalt Shingles polymer-modified stone matrix asphalt (SMA) surface course containing FRAP/RAS was produced and placed as an overlay test strip on the eastbound I-90 to southbound I-39 exit ramp near MP 62. The FRAP/RAS-HMA shoulder mixes were sampled and analyzed for performance through a Surface course. This is the top layer and the layer that comes in contact with traffic. It may be composed of one or several different HMA sublayers. Base course. This is the layer directly below the surface course and generally consists of aggregate (either stabilized or unstabilized) or HMA. Subbase course. HOT- MIX ASPHALT (HMA) BINDER AND SURFACE COURSE . While its use is not required, his checklist has been prepared to provide the field inspector a t summary of easy-to-read step-by-step requirements relative to the proper construction of HMA Binder and Surface Courses (Section 406 of the Standard Specifications). The following

HOT-MIX ASPHALT – BINDER AND SURFACE COURSE (BDE) Effective: July 2, 2019 Revised: November 1, 2019 Description. This work shall consist of constructing a hot-mix asphalt (HMA) binder and/or surface course on a prepared base. Work shall be according to Sections 406 and 1030 of the Standard Specifications, except as modified herein. Materials.
