In addition, a linear trend can be also observed between these two parameters, \({AR}_{50}\) and \(\beta\), which implies that, for the aggregates used in construction materials such as asphalt or concrete, its value does not need to be measured: $$AR_{50} = 0.56\beta + 0.42;...

Usually, the employment of RCA can enhance the moisture resistance of asphalt concrete in terms of permanent deformation [87,178]. However, this is related to many factors, such as the gradation of the mix, the aggregate shape, and the quality of the RCA. Therefore, for the design of ...
The engineering properties of building materials (e.g., asphalt mixes and cement concrete) are influenced by the morphological characteristics (shape, angle, and texture) of the aggregates [15]. Therefore, suitable evaluation methods and indicators can better quantify the morphological characteristics ...
Presently, coarse aggregate gradation is one of the most important technical indicators of asphalt concrete pavement aggregate, which has a significant impact on pavement performance [1,2,3]. Due to the different qualities of aggregate produced by many aggregate processing manufacturers, before using ...
