This guide covers the initial setup and basic operation of your gauge from powering on to taking a measurement. Please refer to the Operators Manual for more details. The following initial steps are recommended to start taking measurements with the NoNuke. The gauge operation accuracy can be checked at any time by using the Verification function in the menu item. Refer to the manual to periodically verify the operation of the gauge.

Input Max Density

NoNuke measures % compaction based on the MAX Density input by the operator. In NoNuke, you can easily change the MAX (lab determined) density value as needed to
accurately measure % compaction. To set the daily MAX density value complete the following steps.

From the READY screen, press the key on the keypad. Press or to change the value or confirm the current value. This value can be the same as the Gmm converted to density units provided by the lab and can be changed as needed to account for product variations. Press to change the displayed value, to use the displayed value, or ESC to exit.| MAX: #PCF Change Value?

or to Exit ---|---

Note: The max density is used to calculate percent compaction. For accurate measurements with the NoNuke, it is necessary to establish a density offset for a specific mix.

Input Mix Information: mat thickness and max aggregate size

The NoNuke has a dedicated area for storing important mix parameters. This can be done under Menu item 11. Details on entering this mix information can be found in the Operators Manual. Under this menu item, you can (1) Select an already stored mix information, (2) Review an already entered mix information, (3) enter New mix information, and (4) Erase an already stored mix information.

Take A Measurement

The gauge should be placed making sure there is proper contact between the gauge bottom surface and the pavement. Avoid wet areas.
From the READY screen press on the keypad or push the quick button on the handle, which will measure density, % compaction, air void, road temperature and further information such as GPS location and project information, if applicable. To view GPS and project information, scroll through the screens by pressing or . The GPS screen is only shown if the GPS is enabled through the MENU options. The GPS module is set to disable to preserve battery life. Enable the GPS
module through the menu options.

Density Measurement

The NoNuke is designed to measure asphalt density and display % compaction. The density values measured by the gauge can be easily adjusted by using a density offset based on measurements obtained from cores or previous calibrations.

Determining A Density Offset
The density offset value is equal to the difference between NoNuke measured density and density obtained by analyzing core results. It is recommended that five core locations are tested with the gauge (five readings per location for a total of 25 readings), and then compare the NoNuke density average of all five locations to the core result density averages at those same locations. (AASHTO T343). To use Density Offset you should set the reading mode to Multiple Readings and set the reading number to 5.

Press

to enter the MENU screen and go to menu item 3. READING MODE by pressing <3>. There are three choices in the READING MODE:

Single Reading,
Multiple Readings,
Reading Number.

Press <1> to take a single density reading. Press <2> for Multiple Reding Mode. In this mode selected number of readings are collected and averaged. The default number of
readings in this mode is 5. To change the total numbers to average, select

<3>, Reading Numbers.

Single Reading
Multiple Readings
Reading Number Select #, ESC Exit

Press <3> to review and/or change the reading numbers averaged in Multiple Readings mode. To change the total number of readings, press and enter the new number of readings to the average for each location. Press to exit the Reading Number screen when the correct number of readings is entered. Press again to leave the MENU screens and return to the READY screen.
You can use the single reading mode for controlling the rolling pattern on new pavements. Place the gauge on the mat after each roller pass until no more gain in density is observed with increased number of roller passes. Note, on some projects you may see a rise in density and then a drop at the end or on the next pass. This may indicate a break in the rolling density profile, indicating max compaction has been achieved.

Establishing Density Offset
Make sure the area/spot you want to use for calibration is flat and dry. A reading pattern like the one in the diagram should be used for taking measurements. The idea is to move the gauge between readings to get a representative measurement of the spot that is being tested. 919-875-8371 -Nonuke-Non-Nuclear-Asphalt-Density-Gauge-fig3.png" alt="InstroTek 919 875 8371 Nonuke Non Nuclear Asphalt Density Gauge - fig3" width="234" height="376" />

Place the NoNUKE on the pavement and press (or the remote start button on the handle) to take the measurement.
After each reading, move the NoNuke to the next location in the pattern, and press again. After the fifth reading (or when total of all the readings) are completed,
the NoNuke will display the average density. Record this density and the densities from the other core locations. Take the cores from these locations and measure their densities in the lab. Compare the average gauge readings for all locations to the average of all core density values for the same locations. The difference between these results is what should be used for Density Offset. The difference can be positive or negative. If gauge readings are higher than the core readings, the offset will be negative. If gauge readings are lower than the core results, the offset will be positive.
To add an offset, press

to enter the MENU screens.

Press <1> to turn the Density Offset ON. Note: To avoid faulty readings when gauge is moved from one project to the next, Density Offset is deactivated when the gauge is
physically turned off with the Off key. You must activate the density offset when you need to use a density offset for a particular project.
