Properties of Different Aggregate Types Use As Highway Construction Material

This research is to evaluate the properties of several aggregate types (limestone, granite
and Recycled Concrete Aggregate) used in construction and also to determine the
feasibility of RCA as highway construction material. Feasibility of RCA as highway
construction material needs to be determined due to depletion of natural aggregate
sources that becomes one of the big issues in construction field. The physical properties
of selected aggregates were investigated in term of hardness, shape and specific gravity.
The scope of studies involved would be on towards the various aggregate tests which
include Los Angeles (LA) abrasion test, soundness test, sieve analysis, aggregate impact
value test, aggregate crushing value test, flakiness and elongation test, 10% fines test
and relative density test.
