Void Ratio and Shear Strength of Two Compacted Crushed Stones
for triaxial testing by compacting the crushed stones to standard Proctor density in a vibratory mold. The type of triaxial test used was the consolidated undrained test, in which the compacted, encased specimen is placed in the triaxial cell, the cell pressure is applied, and full consolidation is allowed to take place before testing.

Wich important tests are required on crushed stone
30-03-2009 Drumchaser....triaxial compressive strength is not a test typically run on base materials, particularly crushed stone base (crusher run), as the material is not cohesive and would not hold together for such a test unless it was tested in a triaxial chamber with a membrane and confining pressure....which would have no interpretive relevance to base testing.

Wich important tests are required on crushed stone

However, it was found that the compacted crushed stone layer is very sensitive to excess moisture. In loadcart field tests, rutting failures occurred whenever the moisture content of the compacted crushed stone layer exceeded 5.4%. AFESC reported that rutting failures seemed to be the result of excess pore pressures which were caused by the ...

Stone Compaction: The Ways It'll Impact Your Project
Each type of crushed stone will settle at a different rate and will have a different compaction rate. As a result, various materials will need to be compacted down more heavily than others. Depending on the specific project, you may end up requiring 1/2″-1 1/2″ of extra material in order to achieve the desired overall depth post stone compaction.

Proctor testing of 3/4" clean stone - Soil testing ...
06-01-2005 I agree with BigH in that the nuke can not be used to measure the density of the clean stone accurately due to the air existing in the voids. However, by practice, I found that it can respond to the degree of compaction of the stone, i.e., the more the stone is compacted, the higher the density is. RE: Proctor testing of 3/4" clean stone.

Compaction and Breakage Characteristics of Crushed
24-12-2020 The subsidence of urban pavement is becoming frequent accidents, and backfill is the primary means of remedy. Crushed stone is a commonly used aggregate for backfill material in engineering, and its compaction behavior under load needs to be well understood. In this work, a series of compaction tests were carried out on the same batch of crushed stone samples with the same

01-12-2013 A comprehensive series of drained triaxial compression tests were performed on crushed concrete aggregate (CCA) moist as compacted. When compared to ordinary natural well-graded gravelly soils, the peak strength and stiffness increase more significantly with dry density, while the effect of the degree of saturation during compaction is much less significant.
