instability of surrounding rock and surface subsidence. To study the creep compaction behavior of crushed mudstones, a series of creep tests are conducted. The investigations show that the creep compaction behavior of crushed mudstones is highly dependent on the original grain composition and axial stress applied on the samples.

Compaction itself is basically the action of applying a downward force for consolidation, taking larger and smaller materials and letting them fall and work their way into place. There is a risk of over compaction as you could, especially with larger gravel, break the granules down into smaller pieces and destroying the composition of that gravel.

Dec 31, 1994 This paper presents results of laboratory compaction testing to determine the influence of particle size, size gradation and moisture-content on compaction of crushed rock salt. Included is a theoretical analysis of the optimum size gradation. The objective is to evaluate the relative densities that can be achieved with tamping techniques.
If you do it in layers, it will be clear how much you need to lay down to get your desired depth. I looked at the gravel you are using. I would suspect you might see 12 to 34 inch of compaction, especially if you just laid it down. All you can do is start compaction, see what it looks like and add or rake off a bit to meet you needs.

Sep 26, 2013 What is an appropiate swell factor for in place rock that is excavated and crushed down to 1.5 inch minus crushed stone I was estimating it to be 15. Reply. Larry says. June 9, 2017 at 1032 am. If swell for gravel is 12, then would shrink for compaction be around 10 given its not going to be 100 compaction I was thinking more like 15 ...
Types of compaction There are four types of compaction effort on soil or asphalt Vibration Impact Kneading Pressure Soil Compaction Soil compaction is defined as the method of mechanically increasing the density of soil. In construction, this is a significant part of the building process. If
Jun 24, 2008 Consolidating 34 Gravel. DirtDelight Materials OP 17 Jun 08 0031. Hello all, A project we are starting next week requires 95 compaction on a 9 section of 34 crushed aggregate under the pipe as well as thru pipe zone section. The pipe is 24 h20. As a technician, I have never actually tested the rock for density.

After completion of production, but before compaction, Class 1 and Class 2 crushed rock and PMWMCR base shall comply with the relevant grading requirements of Tables 812.071 and 812.072 corresponding to the rock type and the assigned Los Angeles Value of the material source.
Mar 10, 2019 Factors affecting Compaction of soil. Compaction of the soil is the process where the dry density of soil is increased by reducing air content or air voids present in the soil. This process is an essential part of the construction of any structure, as it strengthens the soil. Many factors influence the degree with which the soil is compacted.
The compaction factor is defined as the ratio of the weight of partially compacted concrete to the weight of fully compacted concrete. It shall normally to be stated to the nearest second decimal place. Compaction Factor Value W1-W W2-W Result of
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 12-1 12 of extra material in order to achieve the desired overall depth post stone ...
Dec 01, 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.
