dc.description.abstract Flat and elongated particle ratio is a shape characteristic for coarse aggregates used in pavements. The ASTM D 4791 is the standard test method to determine flat and elongated coarse aggregate particles in asphalt mixes. However, this method is subjective, making it less reliable to accurate measurements. The objective of this study was to investigate three flat and elongated particles ratios (FERs); 2:1, 3:1 and 5:1 using a modern 3-D laser scanning technique and compare results with ASTM D 4791. Based on the ASTM D4791, the Superpave specification allows for a maximum of 10% coarse aggregates to have FER of 5:1 in asphalt mixes. Eight crushed stones used for road construction in South Africa were investigated. The results indicate that three crushed stones would be rejected by the Superpave specification whereas all eight crushed stones could meet the specification based on the results from the 3-D laser scanning method. en_US
