Asphalt Binder Analyser / Analyzer (ABA 7/35)


 
  • Designed to measure asphalt binder content by loss on ignition
  • Fully compliant with the latest standards, including: AASHTO T 308-10, ASTM D6307-10, & BS/EN 12697-39:2012
  • Avoids the health, environmental & waste management issues & expense associated with the older solvent extraction methods.
  • With reduced emissions due to high temperature afterburner.
  • Controlled via a multilingual touchscreen interface
  • Supplied as standard with English, Spanish, French, Chinese, Italian & Russian language & other options available to order.
  • Automatic calculation of sample weights & results reduces the potential for error.
  • Automatic capture & incorporation of the defined correction factors.
  • Precise weight measurements displayed to 0.1g resolution.
  • Has the capacity for large sample sizes for more accurate results.
  • Average test times from 20 mins for 6mm aggregates, to 45 mins for 40mm aggregates.
  • Permanent (dot-matrix) printed reports with user configured timing.
  • USB data output compatible with most spread sheets.
  • Easy naming, storage & recall of recipes that can be easily transferred between furnaces
  • Simplified menu structure with secure ‘Supervisor’ & ‘Operator’ settings

The Test

Flexible enough for most methods derived from the ASTM, AASHTO and BS/EN loss on ignition
standards. The ABA 7-35B replaces the older solvent based test methods.

Calibration factors are first calculated, using either pre-determined asphalt mixes as a benchmark
or aggregate only samples in order to correct for volatile components within the aggregate. Also
the effect of reduced air density over the hot sample is tested and corrected by a calibration
factor.

Sample masses based on the aggregate particle size are collected using standard sampling
methods and the weight before ignition is measured on a balance (or scale) outside the
ABA 7/35B furnace.

The sample is then introduced into the preheated ABA 7/35B and the appropriate test recipe is
entered or selected from the library and run.

For operator safety the ABA 7/35B’s door locks and the test runs to completion. The end point is
automatically detected by the ABA 7/35B using absolute or percentage weight changes
whichever is required for the standard regime that is in use. The test end-point is signalled by an
audible alarm.
