Chapter 51.00 Мб. But for the quarry dust and other combinations of quarry dust and coarse aggregate as fillingFilling was done with proper compaction to achieve the required unit weight of 15 kN 1m3.3 • Each layer of the fill was compacted to get the same density by controlling the weight of soil and thickness of layer.

Effective Depth of Soil Compaction

wheel loading compaction suggest that 0.20-meter (8-inch) lift thickness for fine-grained soils and 0.30-meter (12-inch) lift thickness for coarse-grained soils could be appropriate if proper controlled compaction equipment is employed instead of the blanket use of 0.20-meter (8-inch) lift thickness

Then, if 95% compaction is specified, the minimum acceptable unit weight is: 0.95 X 156.0 = 148.2 PCF. If 93% of solid is specified, or a maximum of 7% air voids are allowed in the compacted mat, then the minimum target value would be 145.1 PCF (0.93 X 156.0). The thickness of the course being compacted does influence its compactability.

How to Determine Number of Passes and Lift

Jul 13, 2020  The calculation of the number of passes for compactors and lift (soil layer) thickness for soil is critical to attain the required degree of compaction. Generally, the lift thickness varies between 15-30cm based on soil type, and the majority of compaction is achieved through the first five passes. One can also use field tests and []

From my experience it depends a lot on how is the compaction done. If you are compacting road crush with a vibratory plate you will get about 10 to 15% compaction. (This is based on you having a stable compacted base first. If you are putting the road crush on top of top soil you will lose more to compaction.)

Base Material Compaction: 5 Expert Tips

Too much fine material (passing 200 sieve) can lead to compaction issues and cause your base to fail over time. Ask your supplier for a sieve analysis and make sure that less than 3% passes the 200 sieve. 3. Mind your lifts. A lift refers to the thickness of a layer of base material installed at one time.

Optimum moisture (Standard) should be in the 10 to 12 percent range - maybe 9? Friction angle is pretty good, CBR (or correlations to subgrade modulus) are very good. Placement moisture content will likely be low coming from the truck. Our stone dust comes from the quarry as the No. 10 screenings that result from making open-graded aggregate. f-d

Stone Dust Doesn't Belong Under Pavers. Here’s Why ...

Stone dust, sometimes called rock dust, is a byproduct of crusher run that’s provided the bedding layer for many a paver project over the years. While it can work in some construction applications, there’s a growing recognition that sand – washed concrete sand in particular – has proven far more stable and exhibits properties that make ...
