May 22, 2018 · Asphalt leveling course is defined as a layer of asphaltic concrete pavement of varying thickness spread on an existing pavement to compensate for irregularities prior to placing the surface or wearing course. As you may or may not know, an asphalt pavement section or structure is made up of multiple and different asphalt layers (lifts or courses). HMA, LVSP HMA, 5E_ Shared Use Path, HMA Snowmobile Wearing Cse – Special (See: 12DS806(F355)) Marshall mixes: HMA, 13A HMA, 36A No AWI is required on the top course, however, if the designer wishes, he or she can use the Aggregate Wear Index (AWI) of 220 minimum. Use PG 58-28 for all mixes, except for HMA, 5E_, which should be PG 64/28. Pave with a 3/4″ leveling course to increase ruggedness, durability, and smoothness. Pave with a 1.5″ wearing course. For driveway resurfacing, 1,500 square feet is approximately $3,690. 5,000 square feet is approximately $7,510. Please call for pricing on larger projects. Driveway Overhaul Package HMA may be placed by hand when it is impractical to use a paver. Successful HMA pavement construction requires good planning, design, construction (materials, subgrade, workmanship) and planned future maintenance. Asphalt pavements are constructed of one or more courses of HMA placed directly on the subgrade or on an aggregate base. HMA 419 Stone Matrix Asphalt Mixture Design, RPS Construction of Plant-Mixed HMA Wearing Course . 422 Bituminous Wearing Course -FJ-1 and FJ-1C . 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).

Prior to constructing the overlay, areas of the pavement that exhibit alligator or fatigue cracking must be repaired to full depth because the base of the existing pavement remains the primary load-carrying element in the flexible pavement after construction 92 A Manual for Design of Hot Mix Asphalt with Commentary HMA wearing course HMA
Mar 20, 2020 · HMA is classified by type depending on the specified aggregate gradation and mix design criteria appropriate for the project conditions. The Department uses the following types of HMA based on the aggregate gradation: (1) Dense Graded HMA, (2) Gap Graded HMA, and (3) Open Graded Friction Course. HMA types are found in the Standard
However, there are no standard test procedures for evaluating the friction of an HMA wearing course during the mix design process. There are two tests for evaluating the polishing properties of an aggregate: British portable skid resistance tester (ASTM Test Procedure D 3319-00 and E
