Balanced asphalt mix design and pavement distress predictive models based on machine learning
Traditional asphalt mix design procedures are empirical and need random and lengthy trials in a laboratory, which can cost much labor, material resources, and finance. The initiative (Material Genome initiative) was launched by President Obama to revitalize American manufacturing. To achieve the …

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 …

Lignosulfonate as an Alternative Filler in Bitumen Stabilised Materials (BSMs)
… including as a partial replacement to bitumen in asphalt mix design due to its similar composition to that of bitumen. In a recent study, the lignosulfonate was seen to have improved the resistance to permanent deformation of an asphalt mix design and was proposed for use as a filler in cold mix …

Digital Mix Design for Performance Optimization of Asphalt Mixture
Asphalt mix design includes the determination of a gradation, asphalt content, other volumetric properties, the evaluation of mechanical properties and moisture damage potentials. In this study, a computational method is developed to aid mix design. Discrete element method (DEM) was used to …

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 …

Comprehensive Evaluation of Asphalt Mixtures in Arid Climatic conditions
… is the leading cause of poor performance in the asphalt-wearing course in Kuwait's arid climatic conditions. The extreme conditions of Kuwait and poor asphalt mix design characteristics have further accelerated the raveling and deterioration of the in-service asphalt pavements. Combating this …

Quantification of the Role of The Effective Binder in the Performance of RAP – WMA Mixtures
… bio-binders…etc.) were incorporated into asphalt mixtures. However, current mix-design specifications evaluate all mixtures containing these different additives/technologies based on volumetric. Further, RAP incorporation in asphalt mixtures is still limited, and the influence of lowered …
