Compaction & Density | RC TECHNOLOGY

Electrical Density Gauge

The Electrical Density Gauge supports the following standards: ASTM D7698

The Electrical Density Gauge (EDG) is determining the moisture and density of compacted soils used in road beds and foundations. The EDG is a portable, battery-powered instrument capable of being used anywhere without the concerns and regulations associated with nuclear safety. Its user-friendly, step-by-step menu guides the user through each step of the testing procedure and cautions the user when values do not correspond to established curves for the material being tested.

Compaction & Density

Sand Cone, Density Apparatus

The Sand Cone, Density Apparatus supports the following standards: ASTM D1556, AASHTO T191

Sand density apparatus determines the in-place density of soils. Set includes 1-gal. (3.79L) threaded jar, detachable double cone consisting of a brass cylindrical valve with a 1/2" (12.7mm) dia. orifice. Valve has stops that prevent rotating past completely open or completely closed positions. Bottom cone is 6-1/2" (165mm) dia. with a flanged opening that fits the opening of the H-4246 field density plate (order separately).

Voluvessel

The Voluvessel supports the following standards: ASTM D2167, AASHTO T205

Voluvessels determine the in-place density of compacted or firmly-bonded soils using a rubber balloon apparatus viewed through a graduated, direct-reading clear plastic cylinder. Humboldt offers two distinctly different models; one, where the plastic cylinder screws into the density plate with the pump assembly mounted on top; and, the other, which has a metal casing protecting the plastic cylinder and the pump assembly mounted to the base. Both designs come with a pressure-vacuum pump assembly, pressure gauge, quick coupler valve, double-graduated cylinder, 10 balloons and a density plate

Density Drive Sampler

The Density Drive Sampler supports the following standards: ASTM D2937

For determining in-place density of soil by driving a thin-walled tube into the soil mass to obtain a relativity undisturbed sample. Typically used to verify compacted fill placement, or to obtain samples from the bottom of shallow excavations. Zinc-plated, steel drive head and sliding weight hammer used with separately ordered drive tubes. Drive head, 10 lb., has shock reducing spring to guard against fatigue failure
