Troxler now offers advanced infrared (IR) technology to measure asphalt content by the NCAT ignition method. The HMA sample is ignited using IR elements. This produces a very clean and efficient burning of the asphalt while limiting aggregate degradation.
The New Technology Oven (NTO) combines this sophisticated oven with an integrated weighing system to continuously measure the bituminous weight loss during combustion and to automatically display the percent of asphalt in the mix. The remaining aggregate can be sieved for gradation analysis.
The NCAT NTO has the ability to control the burn sequence during every minute of a burn cycle. By testing a broad cross section of asphalt mixes, Troxler has developed a series of burn profiles which allow the operator to fine tune each burn based on aggregate types of mixtures.
