The first recycled HMA project was constructed in 1976 on a 4-lane urban highway, in which the original pavement was recycled and replaced with a 175-mm (6.9-in) recycled HMA base, a 40 mm (1.6-in) recycled HMA binder and a 20-mm (¾-in) surface wearing course. The recycled HMA contained 50 percent RAP material.
Asphalt treated base (ATB) is a dense-graded HMA with a wide gradation band and lower asphalt content intended for use as a stabilizing base course. ATB costs less than typical HMA mixes because it can be produced with less expensive aggregates and lower percentages of asphalt binder.

Noise increases with size and HMA aggregate. OGFC Surfaces 96.2 96.8 97.0 97.1 3 ASPHALT PAVEMENT HMA is a state of the art mix design system which replaced the old standard Marshall method of mix design. There are four important HMA parameters which the owner must specify in order to ensure the proper design.
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
HOT MIX ASPHALT PAVEMENT DESCRIPTION 450.20 General. This work shall consist of producing and placing Hot Mix Asphalt (HMA) pavement. HMA mixtures shall be composed of the following: Mineral aggregate, mineral filler (if required), Performance Graded Asphalt Binder (PGAB), and as permitted, reclaimed materials (limited to
Apr 16, 2014 · The grade of asphalt binder selected typically is the same as incorporated into the HMA mix. For most areas, the asphalt binder tack coat material would meet the requirements of a performance

Please confirm that this is correct. If 3/4' thickness is correct will a different mix design be required?
