Model 3430 Plus & 3440 Plus 1–1

INTRODUCTION

Since 1958, Troxler has been the worldwide leader in precision
quality control and measurement equipment for the highway and
construction industry. Troxler’s Model 3430 and 3440 Surface
Moisture-Density Gauges have become the industry standard for
measuring the moisture content and density of construction
materials. With the Model 3430 Plus and 3440 Plus gauges, Troxler
has added a number of new features to the proven technology of the
company’s earlier products to provide increased performance,
flexibility, ease of use, and operator safety.

Using the Model 3430 Plus and 3440 Plus gauges, the operator can
quickly and precisely measure the moisture content and density of
construction materials. Both gauges feature:

♦ Two measurement modes (Soil and Asphalt) for precise

compaction control readings in most construction materials:
Soil Mode: For moisture/density determinations in soil and soil-

stone materials in layers of 4 inches or greater.

Asphalt Mode: For density determinations in asphalt or

hardened concrete layers of 4 inches or greater.

♦ A Nomograph function for density determinations in asphalt

layers of less than 4 inches.

♦ Calibration offsets (density, moisture, and trench) to expand

measurement possibilities, and to enhance gauge readings on
materials that may fall outside the range of factory calibration.

♦ Over 30 functions to facilitate all phases of testing compaction

on construction materials.

♦ A backlit liquid crystal display (LCD) to help the operator read

the display during night construction.

♦ Easy-to-use keypad and user-friendly menus to reduce training

time to increase productivity.

♦ An internally mounted beeper, which emits a short tone in

response to a valid keystroke on the keypad. The beeper sounds
a longer tone if the operator presses an invalid key, if the gauge
displays an error message, or to signal the conclusion of a
measurement.

1–2

♦ A serial port used to connect the gauge to an RS-232 device,

such as a computer or printer.

In addition to the items listed above, the Model 3440 Plus gauge
includes the following features:

♦ A backlit keypad for greater ease of use in low-light conditions.
♦ A remote keypad, including a 〈START〉 and 〈ESC〉 key, at the

top of its source rod housing. The remote keypad reduces the
amount of bending and stooping the operator must do while
operating the gauge.

♦ A USB port, which can be used to output data to a USB printer

or flash drive. A list of compatible USB devices is available at:
www.troxlerlabs.com/PRODUCTS/PRODLIT/otherlit.shtml

.

♦ In addition to its internal beeper, a louder, external beeper is

included on the Model 3440 Plus. The external beeper performs
the same functions as the internal one, and can be enabled or
disabled as desired by the operator.

The Model 3440 Plus can also be equipped with an optional global
positioning system (GPS) receiver. The GPS receiver enables the
gauge to store precise GPS coordinates, along with the standard date
and time stamp, for each measurement. For more information on the
GPS option, refer to Appendix I.

The Model 3430 Plus and 3440 Plus gauges meet or exceed all
applicable American Society of Testing and Materials (ASTM)
standards (or corresponding equivalent), including:

♦ ASTM D-2950: Standard Test Method for Density of

Bituminous Concrete in Place by Nuclear Method.

♦ ASTM D-6938-06: Standard Test Methods for In-Place Density

and Water Content of Soil and Soil-Aggregate by Nuclear
Methods (Shallow Depth)

NOTE

As of November 2006, ASTM D-6938-06 replaces ASTM
D-2922: Standard Test Methods for Density of Soil and
Soil-Aggregate in Place by Nuclear Methods (Shallow
Depth) and ASTM D-3017: Standard Test Method for
Water Content of Soil and Rock in Place by Nuclear
Methods (Shallow Depth).

THEORY OF OPERATION

This chapter provides a brief description of the theory of operation
of the Troxler Model 3430 Plus and 3440 Plus Surface Moisture­Density Gauges. The direct transmission and backscatter modes of
operation are illustrated, along with an explanation of the
cesium-137 source, americium-241:beryllium source, and detector
geometry.

2. OPERATION THEORY

Model 3430 Plus & 3440 Plus 2–1

DENSITY

The Troxler Model 3430 Plus and 3440 Plus Surface Moisture­Density Gauges use two modes of operation: direct transmission
mode (with the source rod extended into the material to be
measured) and backscatter mode (with the source rod in the
backscatter position, just above the surface of the material). Source
rod positions are described in Chapter 3.

WARNING

The source rod should always be in the SAFE
position when the gauge is not in use.

In the direct transmission position, the source rod extends through
the base of the gauge into a pre-drilled hole to a desired depth.
Photons from the cesium-137 (Cs-137) source in the source rod pass
through the test material. While passing through the test material,
the photons collide with electrons and lose energy. A high material
density increases the probability of these photon collisions. This
decreases the number of photons that reach the Geiger-Mueller
(G-M) detectors in the base of the gauge. Thus, the number of
photons reaching the detectors is inversely related to the density of
the material: the higher the density of the material, the fewer the
photons that reach the detectors. Using the gauge calibration, the
gauge software converts the G-M detector counts to a density value.

In the backscatter position, the source rod is lowered to the first
notch below the SAFE (shielded) position. This places the source
and the detectors in the same plane, with the source just above the
surface of the material. Shielding between the source and detectors
greatly reduces the number of photons reaching the detectors in a
direct path from the source. Thus, the photons from the Cs-137
source must travel into the test material and scatter (or reflect) at
least once to reach the G-M detectors. The detectors in the gauge
base count these scattered photons.

2–2

MOISTURE

The gauge uses the principle of neutron thermalization to monitor
the moisture content of a material. The gauge includes an
americium-241:beryllium (Am-241:Be) source that is fixed in the
gauge’s base. Fast neutrons emitted by the Am-241:Be source pass
into the test material. Multiple collisions between the fast neutrons
and a similarly sized mass (such as the nuclei of hydrogen atoms)
cause the neutrons to slow to the point where further collisions with
hydrogen or other materials will not continue to reduce the neutron
energy further. These neutrons are said to have been thermalized.

The gauge contains a helium-3 detector that is sensitive only to
thermalized, or “slow,” neutrons. As a result, the moisture counts
relate directly to the amount of hydrogen in the material. Using the
gauge calibration, the gauge software converts the helium-3 detector
counts to a moisture content. (Note that the helium-3 detector is in
the same plane as the Am-241:Be source. Therefore, moisture
measurement is similar to a density measurement taken in
backscatter mode, as described earlier in this chapter.)

The depth of measurement is defined in terms of a maximum depth
beneath the surface of the material being measured. Of the neutrons
counted by the gauge, 98 percent will penetrate no deeper than the
depth of measurement. The depth of measurement is a function of
moisture content. The following equations can be used to determine
the approximate depth of measurement.

Depth (inches) = 11 – (0.17

Depth (mm) = 280 – (0.27

CALIBRATION

Troxler calibrates the gauge at the factory and recommends that it
always be calibrated by an authorized Troxler service center. For a
list of Troxler and authorized Troxler service centers, refer to page
iii of this manual or visit the Troxler website at
www.troxlerlabs.com/SERVICES/services.shtml

The operating range of the gauge is from 1100 to 2700 kg/m
(approximately 70 to 170 pcf).

OFFSETS

The factory calibration provides accurate results for the majority of
materials encountered in construction. If the gauge is to be used to
test materials not covered by the factory calibration, the readings
can be adjusted using an offset.

Perform a density offset if the test material is outside the density
range for average soil or if the material composition varies from
average soil/asphalt. Perform a moisture offset if the test material
contains hydrogenous materials (other than water) or materials that
absorb neutrons. Materials such as cement, gypsum, coal, mica, and
lime all contain chemically bound hydrogen that will cause the
gauge to display a moisture content that is higher than actual.
Material such as boron and cadmium are neutron absorbers and will
cause the gauge to display a moisture count that is lower than actual.

Vertical structures scatter neutrons and gamma photons back to the
gauge. This could result in inaccurate moisture and density readings.
To take readings in a trench or within 0.6 m (2 ft) of a large vertical
structure, perform a trench offset.
