This is a laboratory run test that determines the maximum theoretical dry density of soils utilizing a lb. hammer dropped at a height of 12 inches to compact layers of soil in a standard mold. The test is used to define the optimum level of soil or aggregate that can be compacted into a unit volume with

1. (a) This method is used to determine the inplace density and moisture content of compacted soil and soilaggregate mixtures to a depth of 12 inches with a nuclear gauge. This test method is especially suited for soils of a specified gradation such as aggregate base course, or fine soils of a consistent· nature.

Bulk density of aggregate is the mass or weight of the aggregate that is required to fill a container of a specified unit volume. The percentage of space or voids between the individual particles and in a unit volume of the aggregate mass is known as a void percentage.

density of the lightweight concrete between 90 and 115 lb/ft3. Lower concrete density may be specified for non structural applications. ASTM C567 is the standard test method for determining the density of structural lightweight concrete in various conditions and the relationships between them.

Jul 30, 2012· Now level the top surface of container by rolling a rod on it. After that, weight the aggregate mass that is inside the container and divide it by the volume of container. This will give you the bulk density of the loose aggregates. Compacted Bulk Density. Compacted bulk density can be determined by filling the container in three layers and tamped each layer with a 16mm diameter rounded nosed rod.

Required course and examination for continued certification as a Soils and Aggregate Inspector. The course will include a review of important topics and instruction on changes in the industry, equipment, specifications and test procedures. Cost: for Members/ for NonMembers.

Standardization requires how long of a Test? Nuclear gauge standardization requires 14 minute reading or 4 1 minute readings. Nuclear Density Testing DirectTransmission Requires the predrilled hole to be be how much deeper than the test probe.

This test method covers the determination of bulk density ("unit weight") of aggregate in a compacted or loose condition, and calculated voids between particles in fine, coarse, or mixed aggregates based on the same determination. This test method is applicable to aggregates not exceeding 125 mm [5 in.] in nominal maximum size.

Apr 01, 2017· This test method covers the determination of bulk density ("unit weight") of aggregate in a compacted or loose condition, and calculated voids between particles in fine, coarse, or mixed aggregates based on the same determination. This test method is applicable to aggregates not exceeding 125 mm [5 in.] in nominal maximum size.

Density of Coarse Aggregate Aggregate which occupy nearly 80 to 85 % volume of concrete are most important part of the concrete or RCC. However, it is well recognize that physical, chemical and thermal properties of aggregate substantially influence the properties and performance of concrete.

Record the density test count as DC for test 1 on the worksheet. MC for the moisture test count and record the moisture test count as MC for test 1 on the worksheet. Calculate the percent density (%NPR) using the following formula. V. Report A. Optimum moisture content (OM) DOTD TR .

VDOT Soils and Aggregate Compaction Chapter 6 | 3 DETERMINING FIELD DENSITY MOISTURE CONTENT WITH THE NUCLEAR GAUGE The Nuclear Moisture Density device (or Nuclear Gauge) is specifically designed to measure the moisture and density of soils, aggregates, cement, and lime treated materials, and to measure the density of asphalt concrete.

GeoTesting Lab Services provides material testing including aggregate, concrete, asphalt, contaminated soils, grout, amended soils (soilcement, soillime, soilbentonite), slurry, controlled lowstrength materials (CLSM), plastics, polymers, recyclables, and solid wastes

May 25, 2019· The Proctor soil compaction test is performed by measuring the density, or dry unit weight, of the soil being tested at different moisture content points. The aim of the soil test is usually to determine the optimum moisture content for the soil. In addition to soils, other substances, such as aggregate, gravel, or sand, may be measured.
