NCAT Asphalt Content Furnace

Proven ignition method for determining asphalt content.

Barnstead International and the National Center for Asphalt Technology have developed a fast, accurate, environmentally friendly, and cost-effective method for determining asphalt content. For research, quality assurance or quality control, the Thermolyne NCAT Asphalt Content Furnace is for you. A 12-lab round robin field test has been conducted exclusively with the Thermolyne NCAT Asphalt Content Furnace by NCAT. Results and proven performance are documented by NCAT. The Thermolyne NCAT Asphalt Content Furnace has set the standard for the industry in the determination of asphalt content by the ignition method. This system was an integral part of the drafting and eventual passage of the ignition method standard, ASTM D6307 as well as AASHTO T308. The Thermolyne NCAT Asphalt Content Furnace provides asphalt content of bituminous paving mixtures accurate to 0.11%.

The NCAT is Sensitive to Your Requirements…
NCAT System has the capability to accept positive or negative correction factors for use with mixes containing hydrated lime. This unique furnace automatically detects endpoint within .01% of the sample weight. Stability of the sample is reached once the endpoint criterion has been met for 3 consecutive minutes during the test. Endpoint sensitivity is adjustable from .01% to 0.5%. NCAT Furnace software allows you to choose between automatic and manual test mode. In the automatic mode, the endpoint is detected; the software ends the test, prints out the results and beeps. It will continue to beep until the user presses “stop” to unlock the door, this is in accordance with AMRL specifications. In the manual mode, the endpoint is detected; the unit begins to beep but will continue to test until the user presses “stop” to end it. Once the “stop” button has been pressed, the door will unlock and the results will be printed. NCAT Furnace software automatically compensates for weight change due to sample and basket assembly temperature change. This compensation is computed for each sample load tested, unlike competitive models that assign a fixed number to a given range of load sizes. NCAT Furnace software computes test results as calibrated asphalt content per total weight of HMA sample or bitumen ratio per weight of dry aggregate. System contains 24-hour/7-day timer which can be programmed to preheat the furnace prior to arrival of technicians. An RS232 port provides data interface with personal computer for graphical data analysis.
