When performing a field density test, the dry unit weight is compared to the maximum dry weight of the Proctor tests to calculate a percent of compaction. When the required densities are hard to reach in the field, the moisture content should be compared to the optimum moisture content from the lab tests. If field moistures differ more than 2% ...
Proctor Test (ASTM D1557-91) The Proctor, or Modified Proctor Test, determines the maximum density of a soil needed for a specific job site. The test first determines the maximum density achievable for the materials and uses this figure as a reference. Secondly, it tests the effects of moisture on soil density. The soil reference value is ...
G1 Crushed Stone for base course is not the same thing as crusher-run and it is not only a matter of density. It was developed during the late 1950's from single stage crusher-run material that complies with Fuller curve particle grading and …
(3) Crush, screen, and combine materials to create a uniform mixture conforming to the predominant material specifications. (4) If the aggregate contains a by-product material, the department will test the final product for gradation, wear, soundness, liquid limit, plasticity, and fracture as required for the predominant material.
Most of our base materials will care a MDD of 115 to 125 pcf, with optimum in the range of 9 to 11%. Stabilities are good with CBR in the 80+ range. RE: base course aggregate compaction. BAWANY (Civil/Environmental) 25 May 09 00:56. The lab proctor value needs to be achieved in the field with a plus minus moisture.

tests at various dry densities, using the field moisture content. The field density shall then be measured at a number of points using the sand replacement method and the CBR deduced from the mean of the field density measurements. ii. If more than 10% of the material is retained on the BS 20.0 mm sieve, the
determined by the achievement of a specified in situ density within a compacted layer in the field. To obtain this required field density full compaction is applied via various pieces of mobile equipment including but not limited to; a pad foot roller, vibrating smooth drum roller, multi-tyred roller, grader and water cart.

The test results were obtained by carrying out field density parallel testing, whereby the density and moisture readings were determined first using a …
The results of these field tests are compared to the target values (see Chapter 5) to determine if the contractor has met specifications for density and moisture content of that lift. Section 303.04(h) and 305.03(a) of 2007 Road and Bridge Specifications stipulates that …
This test is used to determine the maximum dry density for any soil and to determine how much soil must be compacted to ensure the stability of a structure and prevent damage from settling. The standard proctor test is generally performed in the labs. The standard proctor test is a soil compaction test which ensures that how its density changes with …
Crusher run gravel. CD triaxial tests were performed using crusher run gravel that was scalped on the ½-inch sieve size. The grain size distribution curve for the scalped gravel is shown in Figure D.6. Density tests were performed on unscalped and scalped samples to provide a means of correlating field (unscalped) densities with lab
For the results of a field density test to have meaning, a re f e r ence point is needed. There are two tests that pro-vide a re f e rence point for granular soils. One (ASTM D 4524) determines the minimum index density of a co-hesionless (granular) soil and the other (ASTM D 4253) d e t e r mines the maximum index density of the soil.
over each test site. Density tests were made with a water balloon volu meter during various stages of the rolling operation. The data are being used in an attempt to define a mathematical or graphical expression for the maximum field density of the material relative to the percentage of coarse aggregate present.
aggregates, referred to herein as primary crusher run and crushed concrete. For the field evaluation, full-scale test sections were constructed with these large-sized aggregate materials over a very weak engineered subgrade and subjected to accelerated pavement testing.

Most field compaction tests are now made using nuclear density gages that employ a cesium element. Nuc gages can have significant errors if the extendable probe is located next to a rock > 3 inches across. In rocky fills the operator should always rotate the probe 90 degrees and take a second reading, recoding the lower of the two values.
Procedure for Sand Cone Test. Take an empty sand cone and weight it (W1). Again fill it with known value of sand and reweigh it to get exact weight of test sand (W2). Now, go to field and place the hole plate where you want to test the density of soil. After that dig the soil gently deep about 4 to 5 inches with the help of hole base plate.
FIELD DENSITY BY THE SAND CONE METHOD (A Modification of AASHTO Designation T 191) SCOPE 1. (a) This method is used to determine the density of compacted soils or aggregates by determining the weight and moisture content material removed from a test hole and measuring the volume of the test hole.

One in-place field density test will be made for each sublot. Test locations will be determined by the Engineer on a random basis in accordance with statistical procedures contained in ASTM D 3665. The percent compaction of each sampling location will be determined by dividing the in-place field density of eachsublot by the average
