Anchor: #i1013899 Section 6: Hot-Mix Asphalt Pavement Mixtures Anchor: #i1013905 6.1 General. Hot-mix asphalt (HMA) is a generic term that includes many different types of mixtures of aggregate and asphalt cement (binder) produced at elevated temperatures (generally between 300-350ºF) in an asphalt plant.

Overview Hot mix asphalt (HMA) pavement refers to the bound layers of a flexible pavement structure. Asphalt pavement material is a precisely engineered product composed of about 95 percent stone, sand, and gravel by weight, and about 5 percent asphalt cement, a petroleum product. Asphalt cement acts as the glue to hold the pavement together. Our HMA is mixed at our asphalt production There is clear evidence that this type of wearing course is susceptible to studded tire wear and therefore it is a rarely used mix. Class E. Dense-graded 1-1/4 inch HMA primarily intended for use as a base course. This was WSDOT’s “standard” base course paving mix that could also be used as a heavy duty surface mix. 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 303-93 [Re-approved 2003]), and the acid insoluble residue CHAPTER 11 BONDED WEARING COURSE 11.1 OVERVIEW A bonded wearing course (BWC) is a gap or open graded, ultra thin hot-mix asphalt (HMA) mixture applied over a thick polymer modified asphalt emulsion membrane. The emulsion membrane seals the existing surface and produces high binder content at the interface of the existing roadway surface and The word "curing" appears more appropriate for cold asphalt mixtures (CAM) whereas for hot-mix asphalt (HMA) "cooling" and, afterwards, "aging" is what you should focus on.

A turnaround is an area designed for extra parking or for backing up before driving forward out of a driveway. It’s a useful feature if you want to avoid backing down the driveway or onto a busy street.

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
