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.

Asphalt Pavement Guidance. 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 (RHMA-O-HB). The engineering design of ...

It is not intended to take the place of asphalt pavement design done by professional engineers using project specific data. However, it will provide the owner, architect, engineer, developer, and/or government official with basic guidelines to use in the absence of professional services.

Asphalt pavements are made of an aggregate base layer and an asphalt pavement layer. The thickness of each layer is critical to resist the expected traffic loads and protect the subgrade. Therefore, asphalt pavement design is the process of determining the proper thicknesses of the aggregate base and asphalt pavement layers by defining the ...

Pavement Design. ADOT performs pavement design using the following methods: The 1993 AASHTO Guide for Design of Pavement Structures*. The Structural Overlay Design for Arizona (SODA) procedure*. *Upon approval, ADOT uses "AASHTO's Mechanistic – Empirical Pavement Design Guide" in parallel with the design methods mentioned above.

considered during the pavement design development process. The milestones include Preliminary Pavement Design (no later than 30% (Stage 1) of overall project development), Final Pavement Design (by 60% (Stage 2) of overall project development), and Pavement Design Validation at 90% (Stage 3) of overall project development).
