• ASTM D6925-09 - Standard Test Method For Preparation

    Standard Test Method For Preparation And Determination Of The Relative Density Of Hot Mix Asphalt (HMA) Specimens By Means Of The Superpave Gyratory Compactor. This test method covers the compaction of cylindrical specimens of hot mix asphalt (HMA) using the Superpave Gyratory Compactor (SGC). This standard also refers to the determination of the relative density of the compacted specimens at any point in the compaction process.

  • ASTM D1461- Moisture or Volatile Distillates in Asphalt Mixtures

    The Dean Stark moisture test apparatus is used to determine the water content in petroleum products, tars, emulsified asphalts and other bituminous materials by the distillation method. The distillation process allows the water in the test sample to be isolated and collected in the receiver of the Trap.

  • ASTM D2041 Test Method for Specific Gravity and Density of Asphalt Mixtures

    Vacuum pycnometers are used to hold samples under vacuum pressure during a Rice Test for ASTM D2041 tests the Specific Gravity and Density of asphalt mixtures are fundamental properties whose values are influenced by the types and amounts of aggregates, asphalt binder, and other materials present in the mixtures.

  • ASTM D2872 - Effect of Heat and Air on a Moving Film of Asphalt

    The Rolling Thin-Film Oven Test method is intended to measure the effect of heat and air on a moving film of semi-solid asphaltic materials. The effects of this treatment are determined from measurements of the selected properties of the asphalt before and after the test.

  • ASTM D6648 - Testing Flexural Creep Stiffness of Asphalt Binder

    Test Method for Determining the Flexural Creep Stiffness of Asphalt Binder Using the Bending Beam Rheometer consisting of a fluid bath base unit, a three-point bend test apparatus, an external cooling unit with temperature controller and a calibration hardware kit with carrying case.

  • ASTM D6521 - Aging Asphalt Binder Using a Pressurized Aging Vessel (PAV)

    This practice covers the conditioning of asphalt binders to simulate accelerated aging (oxidation) by means of pressurized air and elevated temperature using a Pressurized Aging Vessel (PAV). This is intended to simulate the changes in rheology which occur in asphalt binders during in-service oxidative aging.
