Aug 03, 2009The materials which are used in the construction of highway are of intense interest to the highway engineer. The pressure up to a penetration of 12.5 mm and it's ratio to the bearing value of a standard crushed rock is termed as the CBR. The test is simple and has been extensively investigated for field correlations of flexible pavement

GENERAL CHARACTERISTICS Aggregates have three primary uses in highway construction 1) As compacted aggregates in bases, subbases and shoulders 2) As ingredients in hot mix asphalt 3) As ingredients in portland cement concrete Aggregates may also be used as special backfill material, riprap, mineral filler, and other less significant uses.

Chapter 4 Procedures for Approving Aggregate Sources
Class A includes crushed aggregates from quarries with rock types such as gneiss (metamorphic rock), quartzite, and granite. Class B typically covers all non-Class A crushed rocks. Class C includes natural and partially crushed gravels, while Class D is a mixture of two or more classes of aggregates.
Crushed stone, also called road metal, is used because gravel with fractured faces will stay in place better than rounded river pebbles. A good gravel for a gravel road will have a higher percentage of fines than gravel used as a subbase for a paved road. This often causes problems if a gravel road is paved without adding sand and gravel sized

The scenario used in this paper is based on portions of a field scale project, constructed along a highway in Lodi, Wisconsin (USA), that used multiple industrial by-products for roadway stabilization (Edil et al., 2002).The project constructed several sections of roadway using different recycled materials in the road sub-base, as well as a control section using crushed rock.
