Hot-mix Aspahlt Performance Testing
Advanced Performance Testing
Engtec Consulting Inc. owns and operates a Dynamic Loading Frame manufactured by Controls with a 30kN load capacity and -50°C to +80°C thermal chamber, that is able to undertake the following types of testing:
- Beam Fatigue Test – AASHTO T 321 (Fatigue Life of Compacted Asphalt Mixtures Subjected to Repeated Flexural Bending);
- Disc-Shape Compact Tension (DCT) – ASTM D7313 (Fracture Energy of Asphalt Mixtures Using Disc Shape Compact Tension);
- Semicircular Bend Geometry (SCB) – AASHTO TP 105 (Fracture Energy of Asphalt Mixtures Using the Semicircular Bend Geometry);
- Flexibility Index Test (FIT) – AASHTO TP 124 (Fracture Potential of Asphalt Mixtures Using the Flexibility Index Test and Semicircular Bend Test – SCB);
- Indirect Tensile Test – AASHTO T 322 (Creep Compliance and Strength of Hot Mix Asphalt Using Indirect Tensile Test);
- Indirect Tensile Test – ASTM D7369 (Resilient Modulus of Bituminous Mixtures by Indirect Tensile Test);
- Dynamic Modulus, Flow Number and Flow Time – AASHTO T 378;
- Cyclic Fatigue Test– AASHTO TP 107 (Damage Characteristic Curve and Failure Criterion Using the Asphalt Mixture Performance Tester (AMPT);
- Thermal Stress Restrained Specimens Tensile Strength (TSRST) Test – AASHTO TP 10;
- Interlayer Shear Strength (ISS) Test – AASHTO TP 114 – (Texas Overlay Test); and
- General Stress – Strain Testing.
In addition, Engtec owns and operates a state-of-the-art Hamburg Rut Wheel Tester (HRWT) that complies with AASHTO T 324 manufactured by Controls. The state-of-the-art equipment that Engtec operates has been used on the following projects to assess the performance of the hot-mix asphalt mixes:
- Highway 427 Expansion
- Region of York – Intersection Mix Assessment
- Region of York – Viva Next – York RapidLink Constructors
- Bridge Deck Membrane and Hot-mix Asphalt System – McAsphalt Industries Ltd.
- Stone Mastic Asphalt Patching Mix – Duron Canada
LET’S CREATE TOGETHER, LET’S CREATE FUTURE!
This is a direct result of the dedicated service level that is maintained for all projects irrespective of their value.
