Contiguous aggregate packing as common principle for benchmarking asphalt density, stiffness and permeability control

Horak, Emile; Komba, Julius Joseph; Maina, J.W. (James); Sebaaly, Haissam; Muller, Joanne (Elsevier, 2022-04)

Contiguous aggregates are aggregate sizes that consecutively follow a typical aggregate grading curve. Porosity calculation is possible for a binary or longer ranges of contiguous aggregates. Porosity is a fundamental ...
Monitoring permeability potential of hot mix asphalt via binary aggregate packing principles correlated with Bailey ratios and porosity principles

Horak, Emile; Maina, J.W. (James); Myburgh, P.; Sebaaly, Haissam (South African Institution of Civil Engineering, 2019-09)

Asphalt mix designs tend to optimise the load transfer via aggregate skeletons as main mechanism to provide rut resistance, often to the detriment of durability. Permeability, as a significant durability indicator, is ...
Optimizing asphalt mix design process using artificial neural network and genetic algorithm

Sebaaly, Haissam; Varma, Sudhir; Maina, J.W. (James) (Elsevier, 2018-04)

Selection of aggregate gradation and binder content for asphalt mix design, which comply with specification requirements, is a lengthy trial and error procedure. Success in performing mix design rely largely on experience ...
