The effect of Coarse Aggregate sizes on their Physical Properties
Laldintluanga H. ; Rebecca Ramhmachhuani ;
Rock aggregates are the most fundamental material of highways, railroads, and other construction activities. Rocks from two different quarries were evaluated to determine the impact of aggregate size on the performance of materials. This study is to find out the effect of size on physical parameters of aggregate used in flexible and rigid pavement. In order to determine the effect of aggregate size on their physical properties, different sieve sizes were selected. The sizes are divided into four categories according to IS sieve standards: R1 (20 mm-16 mm), R2 (16 mm-12.5 mm), R3 (12.5 mm-10 mm), and R4 (10 mm-4.75 mm) for aggregate impact value, aggregate crushing value, water absorption, and specific gravity. It is observed that the larger size of aggregate has given better results in their physical parameters.
