base course aggregate compaction

Jul 12, 2009· 4 7% OMC (optimum moisture content) seems a bit on the high side for pavement base courses I have used It would suggest that you are not using crushed stone aggregate and that your base course material is a bit on the sandy side - or, forbid, the base course has significant fines that might be clayey in nature (high PI) 5...

Proctor compaction test

The Proctor compaction test is a laboratory method of experimentally determining the optimal moisture content at which a given soil type will become most dense and achieve its maximum dry density The test is named in honor of Ralph R Proctor [ de ] , who in 1933 showed that the dry density of a soil for a given compactive effort depends on ....

Aggregate in Concrete

Crushed stone is preferred in pavement mixes since the higher paste-aggregate bond yields higher flexural strengths (Photo courtesy of the PCA) Moisture Control Figure 2 - Aggregate moisture content plays a part in concrete workability...

Aggregates for Concrete

Crushed stone is produced by crushing quarry rock, boul-ders, cobbles, or large-size gravel Crushed air-cooled blast-furnace slag is also used as fine or coarse aggregate The aggregates are usually washed and graded at the pit or plant Some variation in the type, quality, cleanli-ness, grading, moisture content, and other properties is expected...
