DPV® Asphalt

For Dynamic Viscosity of Non-Homogeneous Materials including Emuslified Asphalts

ASTM D7226, ASTM D2397, ASTM D977 and AASHTO Provisional Standards for Asphalts

Features & Benefits

Common Applications:

  • Emusilfied asphalts
  • Marine fuels
  • Suspensions
  • Slurries
  • Residual Oils

DPV® Asphalt is an automated, rotational digital paddle viscometer for measuring the dynamic viscosity of non-homogeneous materials such as emulsified asphalts, marine fuels, residual oils, and slurries at 40 °C, 50 °C, 80 °C and 100 °C. The DPV® Asphalt provides an automated alternative to older, labor-intensive and less precise methods.

Designed specifically for viscosity testing of non-homogeneous materials

  • Meets ASTM D7226, D2397, D977 and AASHTO provisional standard requirements for asphalt emulsions
  • Viscosity range: 30 mPa⋅s (cP) to 3,000 mPa⋅s (cP) in 100-fold increments depending on paddle selection
  • Integrated heating measures dynamic viscosity at 40 °C, 50 °C, 80 °C, and 100 °C ± 0.1 °C. Factory calibrated at 50 °C.
  • Digital display presents viscosity values in mPa⋅s (cP), mm2/s (cSt)
  • Suitable for applications including emulsified asphalts, marine fuels, suspensions, slurries, foods, paints and residual oils

Improves data quality

  • Automated sample processing and testing reduces dependence on operator for quality data
  • Paddle continuously mixes the sample for greater sample homogeneity and more representative sample data
  • Direct temperature measurement of the sample, rather than the bath, provides more accurate measurements and results
  • Viscosity data is automatically calculated and may be transferred to an optional dot matrix printer

Eliminates laborious and tedious sample processing

  • No sieving or sample pre-heating is required, just load the sample and push a button to initiate sample prep and testing
  • Removable sample cup allows for quick and easy cleaning between samples
  • Allows unattended sample processing – save time and labor
  • Completes most tasks in 10 – 30 minutes with less messy post-test cleanup

Reduces safety risks

  • No hot dripping sample or tricky cork removal; no glass components or accessories
  • Heater cup thermostat senses over-temperature fault conditions and removes power to the heater until the temperature is at a safe level
  • Motor shaft and paddle immobilization automatically disables motor power
  • Easier to clean, reduces hazardous/chemical waste

Low cost, easily transportable design

  • Self-contained, compact instrument with no ancillary equipment (e.g. ovens, water baths)
  • Transports easily for field applications. DPV Asphalt is up to 1/7 the benchtop footprint and 1/3 the weight of the traditional Saybolt system
  • Low overall system cost
