Sand cone test is performed to test the field density in highway or road construction. Actually it is the simplest way to check the compaction of the different layers below the surface of the ground.

Jun 8, 2024 · The sand cone test illuminates the level of soil compaction—a key factor when laying foundations, paving roads, and other construction projects. While the procedure may seem direct, mastering it requires art and technical know-how.

In this article, we will discuss how to perform field density test or fdt test of soil by sand cone method. This test is very useful and commonly adopted at site. The sand cone method is one of the most common methods that are used for fdt or field density test in highway construction.

This test method describes the procedure for determining the in-place density and moisture of earthwork through the use of a sand cone or volumeter apparatus. This method may be used in conjunction with either the Standard (AASHTO T-99) or Modified Proctor (AASHTO T-180) Density Test for determining the percent of Maximum Density.

Sand cone apparatus consisting of base plate, cone and sand jar. Standard sand. (Sand shall be kept dry and free flowing). Containers with air tight covers (cylinder molds are satisfactory). Oven, hot plate, stove or Speedy Moisture Tester. NOTE: Calibration of the sand and sand cone apparatus shall be done in accordance with AZ 229. 3.

This method of test is to determine a weight per cubic foot of sand to be used in soil density determinations, and the volume of the sand to fill the funnel and baseplate on the sand cone apparatus. This test method may involve hazardous materials, operations, and equipment.

Jun 15, 2021 · Sand Cone method is an important test for highway and road construction. We use this test to determine in-situ density of the sub-base, base or subgrade of a road project to check if it meets the project specification.

Sand Cone Density is an accurate and reliable test method that has long been used to measure the in-place density of soils. The procedure is described in ASTM D1556 / AASHTO T 191.

Oct 25, 2024 · 1.1 This test method may be used to determine the in-place density and unit weight of soils using a sand cone apparatus. 1.2 This test method is applicable for soils without appreciable amounts of rock or coarse materials in excess of 1 1 / 2 in. [38 mm] in diameter.

Mar 7, 2025 · The Sand Cone Method is a widely used technique to determine the field density of soil by excavating a small hole, filling it with uniformly graded dry sand, and calculating the soil’s density based on the weight and volume of the sand used.
