Pine SuperPave AFG2 Gyratory Compactor
Pine's AFG2 is its third generation gyratory compactor which incorporates the newest technology that laboratory technicians need.

  • Built-in angle measurement capabilities
  • Designed to account for frame compliance and dynamically compensates for varying mix stiffness
  • Internally stores results from 20 previous tests, including gyration number, specimen height, angle of gyration, consolidation pressure and shear per gyration (optional)

Troxler PaveTracker Plus
The PaveTracker Plus electromagnetic sensing device measures the dielectric constant of an asphalt pavement, slab or specimen and relates that constant to the material's density.

  • Quick indication of pavement segregation, areas of low density and overall pavement uniformity
  • Precise readings up to 1.5 inches on recently laid hot mix asphalt
  • Improved sensor cover features simple, self-adhesive disc design using upgraded materials; easy field replacement and installation; and cost-effective replacement kits

Despatch RTF Oven
The Rolling Thin Film (RTF) asphalt oven from Despatch is designed for testing effects of heat and air on moving film of asphalt in accordance with ASTM and AASHTO designations.

  • Maximum temperature of 400 degrees F
  • Digital temperature controls

Anton Paar SmartPave DSR
The SmartPave from Anton Paar is a dynamic shear rheometer (DSR) combined with a new Peltier heating system.

  • New easy-to-use software
  • Fully automatic temperature calibration (no water flow around sample)
  • Fast Peltier heating and cooling

Hydronix Hydro-Probe II
The Hydro-Probe II digital microwave sensor is for on-line measurement of moisture in free flowing aggregates on conveyors or in bins for asphalt production.

  • Robust housing and hard-wearing ceramic face
  • Simple to calibrate
  • Easily connects to control system

Troxler Model 3451
Troxler Electronic Laboratories' Model 3451 moisture density gauges measure moisture and density of soils, aggregate, asphalt and concrete.

  • Includes an on-board Global Positioning System (GPS) and a wireless Personal Digital Assistant (PDA) user interface
  • Measure the density of asphalt overlays from 1 to 4 inches without influence from underlying materials
  • Backscatter density measurement mode for full depth asphalt
  • Direct transmission for lifts of soil, soil aggregate and stone up to 12 inches

Geneq Micro-Deval Apparatus
Geneq's Micro-Deval Apparatus evaluates the abrasion in presence of water for coarse and fine aggregates.

  • Tests the resistance of fine and coarse aggregates to degradation by abrasion
  • Available models include the one, two or three tier
  • Standard with jars, balls, timer and magnet
  • Available with electronic controller

Enviro Tech EnSolv EX
EnSolv EX is a safe, effective extraction solvent that is used to replace Trichloroethylene for asphalt testing.

  • Non-chlorinated, non-flammable, non-hazardous, non-carcinogenic and non-regulated
  • Proprietary, azeotropic formulation is easy to use and provides longer chemical life and less regulatory hassle
  • AASHTO approved and conforms to ASTM D2172, D6368 and D5404

InstroTek Model 3500 Xplorer
The model 3500 Xplorer moisture density gauge from InstroTek Inc. features the most up-to-date electronics, improved performance and straight forward, simple operation.

  • Menu options are easy to read and navigate
  • A backlit LCD screen and special scroll functions allow operators to easily read the two-line display during day or nighttime work.
  • Battery Saver and InteliCharge extend battery life, keeping the gauge on the job instead of on the charger

Gilson SP-55 Quartermaster
Designed to handle large samples required in Superpave specifications, Gilson's SP-55 Quartermaster divides any hot mix asphalt sample for quality control analysis.

  • Field samples of 120 pounds are quickly reduced
  • Large hopper reduces handling of hot material between procurement of initial field sample and production of lab samples
  • Rugged steel construction

Humboldt Roughometer II
The Roughometer II can be used to assess paved and unpaved roads by providing objective and repeatable data regarding the actual roughness level of the surface.

  • Easily mounted to almost any vehicle
  • Gathers data and transfers it to a PC
  • Displays information in International Roughness numbers in both graphic charts and tables
  • Data can be transported to spreadsheet and database programs

Malvern Control and Analysis Software for Rheometers
Malvern Instruments offers a software version for its range of Malvern Bohlin rheometers.

  • Version 6.40 includes flexible data analysis setup and automation and a completely new test type
  • Analysis routines built into the software, including a template wizard, improved model fitting capabilities, Time Temperature Superposition (TTS) analysis, and data manipulation routines
  • Extended language support
  • Fewer than five mouse clicks are needed to perform an analysis

TransTech PQI301
The TransTech PQI301 is a non-nuclear pavement quality indicator designed and built to take quick, accurate measurement of hot mix asphalt density.

  • For perpetual pavement mixes
  • Takes accurate density readings in three seconds
  • Available in various languages
