Asphalt Selection Guide

This guide will help you select the appropriate Asphalt testing equipment for your specific needs. Accurate asphalt testing is crucial for ensuring the quality and performance of asphalt pavements and other asphalt-based materials. Here’s a breakdown of common asphalt properties and the equipment used to test them:

Asphalt Binder Testing:

  • Penetration:

    • Test: Penetration Test
    • Equipment: Penetrometer
    • Considerations: Needle type, temperature control, standards compliance (ASTM D5, AASHTO T49)

  • Softening Point:

    • Test: Ring and Ball Test
    • Equipment: Ring and Ball Apparatus
    • Considerations: Ring and ball dimensions, heating rate, standards compliance (ASTM D36, AASHTO T51)

  • Ductility:

    • Test: Ductility Test
    • Equipment: Ductility Machine
    • Considerations: Elongation rate, temperature control, standards compliance (ASTM D113, AASHTO T51)

Asphalt Mixture Testing:

  • Marshall Stability and Flow:

    • Test: Marshall Test
    • Equipment: Marshall Testing Machine, Marshall Mold, Compaction Hammer
    • Considerations: Machine capacity, loading rate, mold dimensions, standards compliance (ASTM D6927, AASHTO T245).

  • Indirect Tensile Strength (IDT):

    • Test: Indirect Tensile Test
    • Equipment: Indirect Tensile Testing Machine, Loading Strips
    • Considerations: Loading rate, temperature control, standards compliance (ASTM D6931).

  • Ovens: For heating and drying asphalt samples.
  • Mixing Equipment: For preparing asphalt mixtures.
  • Molds and Compaction Equipment: For preparing test specimens.
  • Core Drilling Equipment: For extracting samples from pavements.
  • Temperature Control Devices: For maintaining specified test temperatures.
