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.
Part You have been tasked to design an interstate highway pavement comprised of hot-mix asphalt (HMA) surface course, a cement treated base course, and a sand-gravel subbase with a predicted design ESAL of 1.2 x 106.The quality of drainage is considered fair because water can be removed from the subbase within a week. Advisory U.S. Department of Transportation Circular an open graded, thin hot-mix asphalt (HMA) surface course called "porous friction course" (PFC) also could achieve good results. This permits rain water to permeate through the course and drain off transversely to the side of the runway, preventing water buildup on the surface and creating a relatively dry pavement condition during rainfall.

SMA Varies with NMAS Base and/or Surface HMA = Hot Mix Asphalt, NMAS = Nominal Maximum Aggregate Size, FC = Friction Course, PPEST = Paver Placed Elastomeric Surface Treatment, SMA = Stone Matrix Asphalt Notes: 1. New designations shall be used. 2. The term “binder” should only be used to mean liquid asphalt.
HMA Ultra-Thin HMA Ultra-Thin offers a simple, cost effective way to maintain roads and streets, as it protects your investment in them. A hot mix asphalt treatment designed specifically for thin lift (3/4 inch) placement, HMA Ultra-Thin was developed for structurally sound pavements that are showing signs of aging, oxidation or minor surface disintegration.
