Quality Control

Asphalt Manufacturing

Quality Control is the responsibility of the contractors and is in place to show they provide quality products with results for acceptance. ATS technicians can assume this responsibility and will test the asphalt as it is produced to ensure the end product meets state or customer specifications. The process may include:

  • Properly collecting samples from the trucks immediately following load-out
  • Monitoring actual mixing temperature of the plant
  • Verifying liquid asphalt content
  • Identifying volumetric properties of compacted asphalt specimens and the specific gravity of the asphalt mix

Asphalt Installation

During construction ATS technicians run testing on asphalt as it is placed in the field. The process may include:

  • Verifying proper rolling patterns are employed
  • Monitoring roadway temperatures
  • Calculating tack, dilution and spread rates
  • Checking density after asphalt paver lays the asphalt mix and after each roller passes
  • Cutting core samples to check for actual density results
  • Ensuring acceptable quality practices are followed

Quality Assurance

Quality Assurance is the continued evaluation of planning, design, and the development of plans and specifications to provide confidence that the product or facility will perform to standards.  This is provided through an unbiased, independent review of all operations, procedures, and equipment used in the Quality Control process. This is achieved by:

  • Observing and inspecting procedures during production and placement
  • Split sample testing
  • Evaluating performance and qualifications of the technicians
  • Verifying equipment is calibrated and in proper working condition
  • Conducting project oversight
  • Reviewing reports and results for accuracy per the project’s requirements

Engineering Analysis

When you find yourself in the middle of a job and your materials are found to be non-compliant, Engineering Analysis Report (EAR) may be required. Our in-house professional engineer, backed by our team of experienced specialists, will conduct a thorough analysis of your material or product and determine possible causes of non-compliance:

  • Scope of Work
  • Develop testing plan
  • Testing, Analysis and Reports
  • Professional recommendations
