COMMERCIAL ITEM DESCRIPTION
FOR THE
TESTER, CONSTRUCTION MATERIALS, MOISTURE & DENSITY
(TCMMD)
1. SCOPE. This commercial item description covers a single unit density and moisture tester with
radioactive sources. The tester is used for measuring the density and moisture content of soils,
and the density of asphalt pavement and other construction material.
2. SALIENT CHARACTERISTICS. The TCMMD will be a one-piece self contained instrument
capable of measuring the density of soils, asphalt pavement, and other construction material.
The TCMMD will be capable of non-destructively measuring the moisture content of soils. It's
desired that the TCMMD be capable of measuring the density of soils, asphalt pavement, and
other construction materials and measuring the moisture content of soils through non-destructive
methods. The TCMMD shall be a measuring device comprised of radioactive sources,
radioactive detectors, a readout device, data storage, and an integral power supply. The TCMMD
shall be capable of testing for density and moisture by backscatter, direct transmission, and
(optional) air gap methods.
2.1 Radioactive sources. The sources shall be doubly or triply encapsulated and sealed having
sealed source certification. The radiological surface dose rate shall not be greater than 40.00
millirem/hour (mrem/hr) at the surface of the TCMMD (neutron and gamma sources).
2.2 Radioactive detectors. The detectors shall be any suitable type of radioactive detectors.
