Asphalt Mixture Design Concepts to Develop Aggregate Interlock
From the beginning of asphalt mixture design it was desired to understand the interaction of aggregates, asphalt, and the voids created during their compaction. In asphalt mixture design, guidance is lacking in the selection of the design aggregate structure and understanding the interaction of …

The Development of Initial Asphalt Mixture Acceptance Criteria Using the SCB test and the I-FIT Test
<p>Cracking has become the primary asphalt pavement distress in Arkansas. Arkansas along with other states have implemented a test to measure rutting resistance. This paper presents research to implement a cracking resistance test to further modify the Superpave volumetric asphalt mixture design …

Evaluation of Balanced Asphalt Surface Mixtures with Conventional and High RAP Contents Using Laboratory and Accelerated Pavement Testing
Balanced Mix Design (BMD) represents an asphalt mixture design methodology that replaces certain traditional volumetric parameters with performance-based testing to address predominant distresses such as rutting and cracking. This approach offers an avenue to properly design and produce engineered …

Balanced Mix Design of Asphalt Mixtures for Intersections
… intersections. Realizing the need for different asphalt mixtures at or near intersections, a past cooperative research between University of Nevada, Reno (UNR) and Nevada Department of Transportation (NDOT) recommended a new gradation specification to be used at intersections. The unique features …

Improving the Laboratory Design of Asphalt Mixtures to Enhance Asphalt Pavement Durability
… including Indiana’s, currently use the Superpave mixture design method to design asphalt mixtures. This method specifies that the optimum asphalt content for a given gradation be selected at 4 percent air voids. During construction, these mixtures are typically compacted to 7-8 percent air voids. …

Analysis of Fine Asphalt Concrete Mixture Gradations from Various Sources to Enhance Durability
… the factors that can influence the durability of asphalt mixtures, is the gradation. This thesis will look into the effect of fine aggregate dense gradations on asphalt mixture durability for sources from the state of Nevada. Based on the available literature, finer gradation asphalt mixes have …
