Asphalt Emulsion 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 an emulsion 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 emulsion to include full-specification testing results. COAs are typically required by the emulsion 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 Verification
  • 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

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 raveling? Bleeding? Premature cracking or rutting? Our team of professionals can perform testing in the lab as well as complete forensic analysis on the road to pinpoint the problem area and recommend solutions. We also provide consulting work to formulate emulsions.

Product Development / Market Intro

Do you have a new product or technology you want to test in real world settings? Our binder lab is located on an asphalt plant’s property, so we have the capability to run research mixes through the plant for real world testing and handling. Let us find champions for your products; our relationships with state departments and contractors are valuable to connect you with the right teams.
