Angularity: The sharpness of edges and corners of particles. The owner/operators are highly qualified to NPTC standards and have a combined 17 years industry experience giving the ability to carry out work to the highest standard. It also seems that the particles angularity has a strong influence on packing density: de Larrard (1999) reported that rounded aggregates give a packing density close to 0.60 while crushed aggregates packing gives values between 0.50 and 0.57.
