You can download the paper by clicking the button above. Particle size distribution is then expressed as a percent retained by weight on each sieve size. It was also found that aggregate blends well with well-shaped, spherical, cubical, rounded and smooth particles that require less cement and water for a given slump than it blended with flat, elongated, angular and rough particles. Elongated and flaky stones are normally not very suitable for road works since the shape and the size make them difficult to compact. b) Maximum permitted value of Elongation Index is 35%. be that specified in co1. Potential Alkali - Silica Reactivity of Aggregates 11. Both flakiness and Elongation tests are not applicable to sizes smaller than 6.3mm (1/4'' sieve). A flaky particle is the one whose least dimension (thickness) is than 0.6 times the mean size. This serious problem can be used in road construction as we are concerned with the road laying technically laying of flexible pavements from mixing the aggregates are being heated to particular temperature of about 1600C and the shredded plastic is mixed with the aggregates transferred to bitumen mixing chamber of temperature 170oC and the test like Softening Point, Penetration, Ductility were seen satisfactory. As a result huge quantity of aggregate material is being needed for the constructions of sub-base in most of the situations.
