optimum moisture content of crushed stone

Suggested Compaction Standards for Crushed Aggregate

maximum density and optimum moisture may be found in a paper by Hveem (4). A major point made in this paper is that many engineers have the highly erroneous im were graded crushed stone, it was decided that only the vibrating roller would be used.

minimum and optimum gradation is delivered to the truck at its optimum moisture content. Every effort should be made to insure that optimum gradation and moisture content are maintained all the way to the job and preferably directly into the mechanical spreader which will plac_e it with a minimum of manip­ ulation to a controlled thickness.

Maximum Dry Density of Soil and Optimum Moisture Content Test

The water content corresponds to this point is called the Optimum water content (O.W.C) or optimum moisture content (O.M.C). Fig.4. Compaction Curve of Soil. The graph shown in figure-3 is the compaction curve. Initially for a water content lesser than O.M.C the soil is rather stiffer in nature that will have lots of void spaces and porosity.

Determining Moisture in Aggregate for Mix Proportioning

Mar 01, 1986· Newly delivered sand, in the early part of the day, will have more free moisture. After a rain the sand may briefly have even more than 6 percent moisture.The coarse aggregate contains less free moisture and varies less. You may have as little as 1 pound of free moisture per 100 pounds of gravel or stone, and seldom more than 2 pounds (1/4 gallon).

Fines inclusion in a crushed limestone unbound aggregate

Mar 01, 2017· Since moisture content variation of 1–2% from optimum during field compaction is common, it was planned to have samples with moisture contents covering ±1.5% of the optimum. Then, soaked CBR tests were conducted on all compacted samples after they were placed in a bath of water for four days per AASHTO T193.

Are compaction tests of #610 crushed stone reliable

Aug 06, 2005· If your stone has become segregated (is not sweet, has “rock pockets”) then you will get these low in-place density test results. Make sure that your stone is well mixed and that it actually meets the gradation requirements for #610, that an accurate proctor is being used, and that your material is at or near the optimum moisture content.
