Asphalt Binder Testing

The ATS Binder Lab is AASHTO accredited and provides an array of asphalt binder and emulsion testing services. These test are completed for quality control of materials as well as for research and development projects.

Whether you are a contractor needing independent testing or a liquid supplier looking for a COA, our experienced technicians are on site to guide you through the process.

COAs / Referee Testing

The ATS binder lab technicians can provide a certificate of analysis (COA) for the asphalt binder to include full-specification testing results. COAs are typically required by the binder supplier to ensure and verify the supplied product meets target specifications enforced by transportation agencies to meet a given project’s requirements.

COAs are essential for several reasons:

  • Quality Assurance
  • Performance Prediction
  • Regulatory Compliance
  • Traceability
  • Dispute Resolution

ATS technicians can provide COAs based on national or international specification requirements or based on a customized specification table.

Tests that may be included are:

Mix Support / Forensics / Failure Analysis

When things don’t go as planned or there is a failure at the roadway, how do you know where to start to diagnose the issue? Is there premature rutting or cracking? Poor density results? Slippage? How do you determine what’s in your binder after it has already been incorporated into the asphalt mix? Our team of professionals can remove that binder from the mix in the lab as well as complete forensic analysis on the road to pinpoint the problem area and recommend solutions.

Looking for a custom blend? Our asphalt binder experts can create a customized formulation adding polymers or additives through low and high shear blending and high shear blending to enhance binder performance. Some common additives include:

  • Elastomers / Rubber (SBS, crumb rubber)
  • Fillers (mineral filler, lime, fly ash)
  • Chemical Additives (rejuvenators, warm mix additives)
  • Plastics (polyethylene, polypropylene, polyvinyl acetate)
