NUCLEAR METHOD TXDOT DESIGNATION: TEXF CONSTRUCTION DIVISION 4 – 7 Asphalt content by nuclear devices book REVIEWED: SEPTEMBER Level the top of the bituminous mixture using a spatula or trowel to an even head (approximately 13 mm [ in.]) above the top lip of the pan.

An evaluation was made of the application of the Troxler nuclear asphalt content gauge, modelto determine the asphalt content of hot bitu­ minous mixes using neutron thermalization.

Parallel data were acquired, where convenient, by the use of a Nuclear-Chicago asphalt content gauge, modelpreviously evaluated. The portable asphalt content nuclear gagE. system was comprised of a portable gage unit, Modela portable scaler, Modeland a calibration standard. The gage consisted of a neutron source of millicuries of Am Be, four He 3 pro­.

investigation of nuclear asphalt content gauge The introduction of new aggregate sources to Louisiana in the mid s has presented problems in asphalt concrete mix design and construction.

Absorptive aggregates such as reclaimed portland cement concrete and some stones now being supplied have made asphalt content determination a critical Author: H R Paul. determining field density & moisture content with the nuclear gauge The Nuclear Moisture Density device (or Nuclear Gauge) is specifically designed to measure the moisture and density of soils, aggregates, cement, and lime treated materials, and to measure the density of asphalt concrete.

* In lieu of Asphalt content by nuclear devices book specified methods, the Engineer may permit the use of a nuclear asphalt gauge. The following standards of The Asphalt Institute are also a part of these Specifications: Construction Specifications for Asphalt Concrete, by The Asphalt Institute.

Mix Design Methods for Asphalt Concrete, by The Asphalt Size: KB. This test method describes the procedures for measuring in-place density and moisture of soil and soil-aggregate by use of nuclear equipment (hereafter referred to as “gauge”).

The density of the material may be measured by direct transmission, backscatter, or backscatter/air-gap ratio methods. Measurements for water (moisture) content are taken at the surface in backscatter mode. Make sure the previous passes have been completed over the entire surface before the next pass is started.

When testing asphalt materials, take a nuclear test for density only, using the Backscatter Method. The above test on aggregates and asphalt materials should be made at three randomly selected points within the area to be tested.

ALDOT ASPHALT CONTENT OF HOT-MIX ASPHALT BY THE NUCLEAR METHOD 1.

Scope This test method covers the quantitative determination of the asphalt content of hot-mix asphalt (HMA) by examining a sample with a device that utilizes neutron thermalization techniques.

The Model B is a lightweight, non-nuclear device for measuring the uniformity of asphalt pavement. This gauge eliminates the need for licensing, safety training courses, and transportation restrictions because the PaveTracker Plus uses electromagnetic sensing technology instead of nuclear.

Asphalt Content Tester Furnace shall be warranted against defective materials, workmanship, and failures for twelve (12) months from date of acceptance covering percent parts and labor cost.

If manufacturer’s standard warranty period is in excess of 12 months, the. ASPHALT CONTENT GAUGE Troxler's Model Microlab Asphalt Content System provides a quick, accurate and safe method of measuring the asphalt content of your bituminous mixes in your lab.

Like the Model C, the Model uses a small nuclear source to measure the asphalt content. The Troxler nuclear moisture density gauges are used by many contractors, engineers, and highway departments for compaction control of soil aggregate, concrete, and full depth asphalt.

The gauges meet or exceed the ASTM standards D, D, and C Asphalt pavement density measurements were made using a conventional nuclear density gauge and a new electrical resistivity device called the “Pavement Quality Indicator.” Five sets of density tests were made at each of nine sites during, or immediately following paving operations between July and September, Cited by: 3.

Design engineers must understand these complexities in order to optimize its use. Whether or not it is used to pave a busy highway, waterproof a rooftop or smooth out an airport runway, Asphalt Materials Science and Technology acquaints engineers with the issues and technologies Missing: nuclear devices.

Nuclear gauges for the express purpose of measuring the asphalt content of bituminous mixes are now commercially available. The purposes of this study were to determine the precision of a Troxler AC asphalt content gauge and to evaluate its accuracy under such variables as aggregate type and gradation, and asphalt content, type, and penetration by: 3.

Hot-mix asphalt (HMA) is a generic term that includes many different types of mixtures of aggregate and asphalt cement (binder) produced at elevated temperatures (generally between ºF) in an asphalt Missing: nuclear devices.

Different types of field density test are being practiced in different parts of the world for evaluation of in-situ soil compaction and knowing the relative degree of compaction. FDT which is acronym of Field Density Test is a Quality Control test carried out at site for knowing the increased density or compaction achieved at site on the soil Missing: nuclear devices.

Overview. The theoretical maximum specific gravity (Gmm) of a HMA mixture is the specific gravity excluding air voids. Thus, theoretically, if all the air voids were eliminated from an HMA sample, the combined specific gravity of the remaining aggregate and asphalt binder would be the theoretical maximum specific gravity.

Theoretical maximum specific gravity can be multiplied by the density of Missing: nuclear devices. A nuclear weapon (also called an atom bomb, nuke, atomic bomb, nuclear warhead, A-bomb, or nuclear bomb) is an explosive device that derives its destructive force from nuclear reactions, either fission (fission bomb) or from a combination of fission and fusion reactions (thermonuclear bomb).Both bomb types release large quantities of energy from relatively small amounts of g: Asphalt.

Warm-up and check the equipment. Daily Most nuclear gauges require a warm-up. Samples of asphalt mixtures were prepared at four different asphalt contents by weight of asphalt mix mass (5%, %, 6%, and %), with three replications per asphalt content.

For base asphalt cement and each modifier concentration, one asphalt cement content was chosen, which met the requirement of Superpave mix design 4% air voids.

Several testing methods have been generally used to detect and measure the segregation of HMA. These include permeability test and nuclear/non-nuclear density test. Williams et al. found that the nuclear moisture/density gauge is capable of accurately measuring both asphalt content and density in a dry pavement condition.

They also pointed out Cited by: 8. devices tested is feasible to replace the nuclear gauge. Additionally, many of the devices do not provide a measure of water content, and thus would require another device to measure water content when water content is required for compaction control.
