asphalt mix design program

When the Strategic Highway Research Program (SHRP) was concluded over 20 years ago, the new Superpave asphalt mix design system was envisioned to include three levels based on the design traffic for the pavement.

Asphalt pavements are recyclable. In fact asphalt is the most recycled product in the United States. So any asphalt that is already in place on a particular site can be delivered back to the plant and reused in the fresh asphalt for the project. A project can get LEED credits for this reuse along with reducing the demand for materials.

Furthermore, the effects of warm-mix asphalt additives, polymers, rejuvenators, and fibers cannot be assessed in the current volumetric mix design method. Therefore, performance tests need to be included as part of the mix design procedure to help ensure desirable pavement performance in the field.

The system includes an asphalt binder specification, a hot-mix asphalt (HMA) design and analysis system, and computer software that integrates the system components. The Superpave binder specification and mix design system include

Balanced mix design (BMD) for asphalt construction is used to design an optimum asphalt content between problems with rutting on one end and cracking on the other. Tests that are used to determine these parameters are the Hamburg wheel tracking test, the overlay test, the ideal cracking test and shear bond strength testing.

Apr 20, 2018· The developed mix design aid tool is compiled into a computer software called Asphalt Mix Optimization (AMO) that can be used by road agencies as a mix design tool. A case study is presented to demonstrate the ability of the model to optimize aggregate gradation and minimize binder content in asphalt mix.

communication among DOTs. To compare the Marshall and Superpave mix design methods and recommend an improved mix design method for TDOT, a wide range of TDOT typical asphalt mixtures were collected, designed and evaluated in this study. The plant mixtures resulted in a high variation of the results of the equivalent Ndesign.

Overview. The use of warm mix asphalt (WMA), reclaimed asphalt pavement (RAP), and recycled asphalt shingles (RAS) has significantly increased in recent years as a result of construction costs and environmental issues. This course is designed to provide information useful for designing mixes and making decisions about the use of WMA, RAP, and RAS.

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 workable.

The Marshall mix design method can use any suitable method for estimating optimum asphalt content and usually relies on local procedures or experience. Sample Asphalt Binder Contents Based on the results of the optimum asphalt binder content estimate, samples are typically prepared at 0.5 percent by weight of mix increments, with at least two ...
