(as necessary). The aggregate gradation for the SMA mixture is on the coarse side of the maximum density line on the 0.45 power chart compared to a dense graded mixture (see Figure 1). Unlike an open-grade mixture, the majority of the voids between the coarse aggregates in a SMA mixture are filled with mineral filler and binder [2].

Concrete is the mixture of cement, coarse aggregate, fine aggregate and water in a definite proportion. The use of many waste materials as coarse aggregate in concrete are reported in the literature [1-17]. The potential of the use of waste pieces of burned pressed clay roof tiles as coarse aggregate in concrete are not studied in detail.

The Effect of Morphological Characteristic of Coarse

The morphological properties of coarse aggregates, such as shape, angularity, and surface texture, have a great influence on the mechanical performance of asphalt mixtures. This study aims to investigate the effect of coarse aggregate morphological properties on the high-temperature performance of asphalt mixtures. A modified Los Angeles (LA) abrasion test was employed to produce aggregates
