Electrical Density Gauge

Electrical Density Gauge Model E (EDGe) is used for determining the density and moisture content of aggregate, soil aggregate compacted type I or II base, or native soil materials that are suitable for shallow foundations, such as secondary roads or base aggregate that is compacted in-place prior to the asphalt or concrete placement at the final grade. The EDGe quality assurance / quality control (QA/QC) system is lightweight, easy to use, and nuclear free.

The laboratory aggregate calibration procedure involves electrical testing of a representative sample of the construction aggregate or soil materials while performing either an ASTM D1557 Standard Test Method for Laboratory Compaction using a Modified Effort of 56,000 ft-lbf/cubic foot or the ASTM D698 Standard Test Method for Laboratory Compaction using a Standard Effort of 12,000 ft-lbf/cubic.

Complies with AASHTO T 399 and is an enhancement of ASTM D7698 that includes a Laboratory aggregate calibration procedure
Nuclear-free device
Accurate and repeatable results that correlate to either ASTM D1557 or ASTM D698 standard
Proctor tests
Does not require highly trained or licensed technicians
Does not require special handling for shipping or regulatory compliance for hazardous materials
Easy-to-learn and easy-to-use with its step-by-step menu
Lightweight and easily transportable
Eliminates costs associated with nuclear gauge
