HMA consists of a mixture of asphalt binder and a graded aggregate ranging from coarse to very fine particles. HMA is classified by type depending on the specified
Basics of Asphalt Mix Design - Asphalt
Asphalt mix design classes, offered by the Asphalt Institute, are usually 3-5 days in length and feature hands-on laboratory experience as well as detailed classroom instruction.

Common types of flexible pavement include hot mix asphalt (HMA), rubberized hot mix asphalt-gap graded (RHMA-G), and open-graded friction course (OGFC). There are also
HMA Pavement Mix Type Selection Guide - FHWA
The HMA Pavement Mix Type Selection Guide provides designers with methods for selecting appropriate mix types while considering factors such as traffic, environment,
HMA Mix Design Fundamentals – Pavement
Mix design is a process to manipulate three variables: (1) aggregate, (2) asphalt binder content and (3) the ratio of aggregate to asphalt binder with the objective of obtaining an HMA that is deformation resistant, fatigue resistant, low temperature crack resistant, durable, moisture damage resistant, skid resistant and
Designing Stone Matrix Asphalt
Keeping the asphalt cement content constant, the mix was fine-tuned by making minor changes in the coarse aggregate and the amount of mortar. [The design asphalt cement

Additives were placed in the dense-graded top course (38 to 51 mm thick) over an unmodified base course (102 to 114 mm) over an existing pavement with severe alligator and thermal cracks. One section included polypropylene fibers and another included polyester fibers, both with AC-20
Asphalt Pavement Thickness and Mix Design - Asphalt
At the start of a mix design project, target temperatures are specified for proper mixing and compaction. These temperatures should be adjusted for project conditions (weather, haul distances, etc.). Whenever possible, variances of more than 25 degrees from the mix temperature should be

The end result of a successful mix design is a recommended mixture of aggregate and asphalt binder. This recommended mixture, which also includes aggregate gradation and asphalt binder type is often referred to as the job mix formula ( JMF ) or
Asphalt Pavement |
Common types of flexible pavement include hot mix asphalt (HMA), rubberized hot mix asphalt-gap graded (RHMA-G), and open-graded friction course (OGFC). There are also two types of rubberized OGFC mixes: rubberized hot mix asphalt-open graded (RHMA-O) and RHMA-O-high-binder
HMA Pavement Mix Type Selection Guide - FHWA West
The HMA Pavement Mix Type Selection Guide provides designers with methods for selecting appropriate mix types while considering factors such as traffic, environment, subsurface pavement structure, existing pavement condition and preparation, and economics. The pavement mix types targeted are Open-Graded Friction
Designing Stone Matrix Asphalt Mixtures - Transportation
Keeping the asphalt cement content constant, the mix was fine-tuned by making minor changes in the coarse aggregate and the amount of mortar. [The design asphalt cement content was 6.5% by weight of mix and the air voids were 2.5%.] The final blend was 75% coarse aggregate, 20% fine aggregate, and 5% mineral
