Asphaltic Concrete Mix Design Marshall Method

Perform a Marshall Mix Design per the Asphalt Institute MS-2 Manual and AASHTO test methods conforming to the Kansas City Metropolitan Chapter of the American Public Works Association, 2001 Edition, APWA Type 4-01 specification (50 compaction blows per face).

Hot-Mix Asphalt Testing for the South African Pavement Design

international hot-mix asphalt (HMA) test methods and modify or adapt them to suit South African road pavement conditions. This paper presents various laboratory HMA test protocols developed as part of the project to revise SAPDM. Large scale laboratory testing was conducted on a standard South Africa asphalt mix with 60/70 penetration grade binder

Manual of Practice

use the most cost-effective methods when patching distressed areas. The patches will also be expected to survive longer and carry more traffic. 1.1 Scope of Manual This manual describes materials and procedures for the repair of potholes* in asphalt-surfaced pavements. The materials and procedures discussed are for cold-mix stockpiled materials and


MS-2 "Mix Design Methods for Asphalt Concrete and Other Hot Mix Types ," and Superpave Series No.2 (SP-2) "Superpave Mix Design" provide in-depth procedures for preparing HMA using RAP and/or RAS for mix design and the determination of a job mix formula (JMF). C. APPARATUS 1.


This study compared the asphalt content (%) of samples taken by each method with the % asphalt content of the mixture taken from behind the paver with a template. The purpose was to ascertain if all methods provide unbiased test results of hot mix asphalt (HMA). Statistically, it made no significant difference which sampling method was followed.

Fix your mix

For further information about RAP and RAS, see chapter 11 in the Asphalt Institute’s “MS-2, Asphalt Mix Design Methods, 7th Edition” available at Blankenship is the Senior Research Engineer at the Asphalt Institute.

Marshall Mix Design Procedure

Sep 29, 2016 · The main objective of the Job Mix Formula, Mix Design Method, Marshall Mix Design method is to determine an ideal and optimum asphalt mix that has following properties :-1. Resistance to permanent deformation: The mix should not distort or be displaced when subjected to traffic loads.

Mixing and compaction temperatures of asphalt binders in hot

This report identifies improved test methods for determining laboratory mixing and compaction temperatures of modified and unmodified asphalt binders. The report will be of immediate interest to materials engineers in state highway agencies and the hot-mix asphalt (HMA) construction industry.

Marshall Mix Design

Free online knowledge for the paving industry. Sample Preparation. The Marshall method, like other mix design methods, uses several trial aggregate-asphalt binder blends (typically 5 blends with 3 samples each for a total of 15 specimens), each with a different asphalt binder content.


The Shelly Company provides a diverse portfolio of the most technologically advanced paving mixtures, such as porous, polymer-modified, recycled, recycled incorporating shingles and foamed warm mix (Eco-Mix brand) asphalts. Unlike hot mix asphalt, warm mix methods use less energy production as well as a more efficient adhesion between aggregate ...

Mix Design Fundamentals | Washington Asphalt Pavement Association

HMA mix design is the process of determining what aggregate to use, what asphalt binder to use and what the optimum combination of these two ingredients ought to be. There are several different methods used to go about this process, of which the Superpave , Marshall and Hveem methods are the most common.

Three Hot Mix Asphalt Types

Jan 14, 2019 · Now that you know the main three asphalt types, you need to be aware of the following tips during the construction process. First of all, the hot mix asphalt shall be transported from a nearby plant to the job site, and the closer the better to maintain proper temperatures.
