Reening Sand And Gravel Handbook
SAND AND GRAVEL AGGREGATE RESOURCES Surficial geology .
The stratigraphy and nomenclature outlined in Pleistocene Stratigraphy of Illinois (Willman and Frye, 1970) and Handbook of Illinois Stratigraphy (Willman et al., 1975) are used in this report to group the sand and gravel resources and related deposits in the state that have similar ages, depositional histories, and physical characteristics.
Soil Compaction Handbook
Sand and gravel obtain maximum density in either a fully dry or saturated state. Testing curves are relatively flat so density can be obtained regardless of water content. The tables on the following pages give a basic indiion of soils used in particular construction appliions.

DENSITY TESTING AND INSPECTION MANUAL
Sand is a noncohesive soil which is not sticky when wet and very loose and fluffy when dry. The natural moisture content of sand is relatively low as compared with clay. Soil mixtures may also contain some amounts of gravel, which is a granular material. By AASHTO definition gravel will pass the 3 inch sieve and be retained on the No. 10 sieve.
