MINERAL AGGREGATES 
Today's highways must have the strength and durability to
sustain high volumes of traffic for many years. Since the
pavements and base courses of these highways are composed
largely of aggregates, these materials must be of a quality
level that will permit satisfactory performance.
Consequently, the role of the aggregate inspector is vital
to securing good highway performance. Design and
construction techniques can never satisfactorily compensate
for the use of substandard aggregates. A well designed and
constructed highway using substandard aggregates will soon
become a maintenance problem. • Sieve Analysis |
