The Bending Beam Rheometer (BBR) performs flexural tests on asphalt binder and similar specimens per ASTM D6648-01 and AASHTO T313-02.
Humboldt FlexPanels provide a simple and highly efficient distribution system for providing air, water and de-aired water for use in permeability and triaxial testing applications.
Humboldt water baths are a perfect match for Marshall and Superpave test applications and meet ASTM D1559, D5581 and D4867.
For those who plan to do triaxial tests in addition to permeability testing, consider using HM-4199B and HM-4199SS Triaxial Cells for the added convenience of using one cell for both tests
The Electrical Density Gauge (EDG) is a nuclear-free alternative for determining the moisture and density of compacted soils used in road beds and foundations.
The GeoGauge is a unique, QC/QA field tool that can be used to measure the uniformity of unbound pavement layers by measuring the variability in stiffness throughout a structure.
Humboldt's NEW HS-5001SD Moisture/Density Gauge provides easier and more efficient operation, data collection and processing, safety and repair than any other gauge in its class.
Portable Skid Resistance Tester is an essential tool for anyone with a duty to minimise the risk of accidents arising as a result of slippery roads and floor surfaces. Originally developed by the Transport and Road Research Laboratory of Great Britain.
