Troxler's Model 3241-D Asphalt Content Gauge enables you to quickly, accurately, and safely test your bituminous mixes for asphalt content using nuclear methods. Used by transportation agencies all around the world, the Model 3241-D provides accurate asphalt content results in as little as five minutes.
No Toxic Chemicals or High Temperature Burns
The Microlab provides the asphalt content measurement without the hazard and expense of the toxic chemicals employed in the solvent extraction method. This method is also beneficial when analyzing the material that may be lost in a high temperature burn oven.
Simplifies Reporting and Reduces Calibration Time
The Microlab downloads test data directly to a printer or computer, simplifying result reporting. Calibration transfer from a centrally located 3241 gauge greatly reduces calibration time for field sites.
The 3241-D gauge meets or exceeds ASTM Standard Test Method D-4125. Troxler's asphalt content measurement equipment is used as the standard test method by more than 25 states and federal transportation agencies. Hundreds of highway construction contractors and testing authorities use the 3241-D for quality control and acceptance testing.
Features
Troxler's Model 3242 Microlab Asphalt Content System provides a quick, accurate, and safe method of measuring the asphalt content of your bituminous mixes in your lab.
In most countries you can possess the Model 3242 without the expense of obtaining a Radioactive Materials License. In states governed by the US Nuclear Regulatory Commission, the savings in licensing fees can pay for the Microlab after just a few months of lab operation. In states or countries with their own license requirements, your savings may be even higher.
The Fastest Burns in the Industry Complete, Clean Burns—Every Time
Simple to Use Just follow these five easy steps: (1) heat the asphalt sample, (2) weigh the sample and divide it across two sample baskets, (3) enter the sample mass, (4) place the baskets in the chamber, and (5) close the door and press a button to begin the test.
Efficient Extremely fast warm-up (only twenty minutes) and recovery times ensure quick, complete burns. The typical burn time for a 1200 gram sample is twenty minutes or less (at 240 VAC).
Instant Results An integrated weighing system continuously measures the bituminous loss during combustion, and the oven displays the percent of asphalt in the mix when the burn is complete. You can then sieve the remaining aggregate for gradation analysis.
ASTM and AASHTO Compliant The oven uses the NCAT ignition method and fully meets and complies with ASTM D6307 and AASHTO T 308.
Superior Serviceability Maintenance is simple and straightforward. Removable panels allow easy access to all components and assemblies.
