Aggregate testsmeasured using round bar sieves, rather than slotted trays. Sieve sizes have also been changed. The remaining tests, such as Polished Stone Value, Aggregate Abrasion Value, and Magnesium Sulphate Soundness, have been retained virtually intact. Aggregate strength is now assessed using the Los Angeles test, which has replaced the Ten Percent
BASICS OF AGGREGATE CERTIFICATION STUDY GUIDECoarse aggregate samples should have a minimum weight of 75 pounds (35 kg). Fine aggregate samples should have a minimum weight of 15 pounds (10 kg). However, with consideration to handling and lifting safety, no single bag or container should weigh in excess of 40 pounds (20 kg).

NOTICE UtahA representative aggregate sample is placed in a calibrated measure and the mass determined. The bulk density is calculated by dividing the aggregate mass by the volume of the measure. Bulk density for this FOP is expressed as pounds per cubic foot (lb/ft 3). Void content is expressed as a percentage and will require knowledge of the G sb (OD) (oven

Effect of Aggregate Characteristics on Texture and Skid ...SmallSize Coarse Aggregate by Abrasion and Impact in the Los Angeles Machine). The LA abrasion loss value is expressed as a percentage of wear (PW) or the percentage of aggregate loss due to the abrasion. Lower PW indicates an aggregate that is tougher and more resistant to abrasion.

Coarse Aggregate Angularity Pavement InteractiveThe CAA test estimates coarse aggregate angularity by visually inspecting a small sample of coarse aggregate and separating the sample into those pieces with a fractured face and those without (Figure 2). If more than one fractured face is specified, the same test can be done using two fractured faces as the decision criteria.

Aggregates for Chip and Seal PavementThe limits vary from to percent, depending on the classification of the aggregate. The percentage is a measure of the degradation or loss of material as a result of impact and abrasive actions. Section details the requirements. Abrasion requirements do not apply to blast furnace slag.
