APTTS- Asphalt Pavement Thermal Testing System

Asphalt Pavement Thermal Testing System (APTTS) is a multipurpose low temperature testing machine that optimizes low temperature performance of asphaltic concrete mixtures.

• Cool or heat an asphaltic concrete specimen at a constant rate or hold a constant temperature
• Simulate actual field conditions with user programmable temperature profiles
• Perform cyclic temperature testing
• Minimises radial and/or transverse forces with dual clevis and rod end assemblies
• AASHTO TP10
  • Thermal Stress Restrained Specimen Test (TSRST)
• prEN 12697 46
  • Uniaxial Tension Stress Test (UTST)
  • Thermal Stress Restrained Specimen Test
  • Relaxation Test (RT)
  • Tensile Creep Test (TCT)

• Determines the failure characteristics of Asphaltic Concrete (AC) specimens when cooled below freezing according to a user defined temperature profile.
• Evaluates low temperature performance of field cores from existing roads.
• Test laboratory compacted cores of new or experimental mixes.
• Demonstrates the effects on low temperature performance of modified binders and from adding modified to standard binders
• Optimise Low Temperature Performance of Asphaltic Concrete Mixtures
• The APTTS software controls test, logs, data, plots the data points, and produces graphs
