INTRODUCTION
Troxler’s Model 3451 Enhanced RoadReader Plus combines the
impressive features of the Model 3450 RoadReader Plus with
advanced global positioning system (GPS) and wireless
technologies to provide unparalleled performance, flexibility, ease
of use, and operator safety.
Like the 3450 gauge, the Model 3451 incorporates the proven
capabilities of Troxler’s 3400 (moisture/density) and 4640 (thin-
layer density) gauges in a single unit that can perform thin-layer,
backscatter, direct transmission, and moisture measurements. In
addition to the features found in the 3450 gauge:
♦
The Model 3451 is controlled using a handheld personal digital
assistant (PDA) , which allows the operator to stand away from
the gauge while operating it via Bluetooth

wireless
communications.
♦
An onboard GPS receiver enables the Model 3451 to store
precise GPS coordinates, along with the standard date and time
stamp, for each measurement.
♦
The Data Manager PDA to PC Model 3451 for Windows XP

software included with the gauge enables the operator to collect
project data from the PDA or gauge on a personal computer
(PC), print project configuration information, and recover data
from the gauge in case of an emergency (such as the loss of the
PDA).
With the Model 3451, the operator can quickly and precisely
measure the moisture content and density of construction materials.
The gauge’s features include:
♦
Three measurement modes ( soil , asphalt , and thin layer ) for
precise compaction control readings in most construction
materials:
Soil Mode: For moisture/density determinations in soil, 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.
Thin Layer Mode: For density determinations in asphalt layers
of less than 4 inches.
