Asphalt Mix Design

Gilson supplies everything you need for testing hot-mix asphalt mix designs, including all of the preparation methods and tests to determine binder content, strength, durability, and physical characteristics.


  • Marshall Testing is the most widely used method for measuring the load and flow rate of asphalt specimens. Gilson supplies everything from Marshall Stability Systems, to Compactors, molds and more.
  • Extractors, Filter Paper & Solvents determine asphalt binder content. Extractors are available in Reflux, Centrifuge and Vacuum models.
  • Ignition Furnaces offer an accurate, efficient and environmentally-friendly way to measure asphalt content in hot-mix asphalt samples.
  • Gilson Quartermaster Asphalt Sample Divider separates large hot-mix asphalt samples needed in Superpave® specifications for quality control analysis.
  • Material Handling Chute enables fast, uniform loading of molds and handling of bulk materials including asphalt, aggregates and soils.
  • SuperpaveTM Heavy Duty Oven is built to handle the heavy loads and rough use from Superpave gyratory molds and large samples.
  • Superpave TM Gyratory Compactors evaluate asphalt mix design while preparing compacted specimens for further testing.
  • Asphalt Mixers are available in portable and industrial-grade laboratory models for thorough sample mixing and blending of materials.
  • Draindown Basket is a simple test to find the level of binder separation during production, transport and placement of asphalt mixes.
  • Hveem-N-Beam Tester accurately displays live load, peak stress and load rate for Hveem asphalt testing, R-Value testing of soil samples and recorded flexural testing of concrete beams.
  • Asphalt Bulk Specific Gravity Device offers a fast, accurate method for bulk specific gravity determinations of asphalt core and gyratory specimens of varying sizes.
  • Asphalt Wheel Trackers accurately evaluate rutting, fatigue cracking and moisture susceptibility for hot and cold asphalt mixes.
  • Rice Shaker for Specific Gravity & Asphalt Rice Test offers repeatable agitation for Asphalt Rice Testing and other specifc gravity deairing operations.
  • AutoRiceTM Controller System monitors vacuum pressure and time, while regulating shaker vibration energy during theoretical maximum specific gravity testing.
