Quality Control / Quality Assurance

Asphalt quality control is about more than just checking a box. QC ensures the longevity and safety of asphalt pavements. Our Asphalt QC Service ensures asphalt producers and asphalt contractors can be worry-free in the areas of:

Meeting project specifications

Calculating tack, dilution and spread rates

Monitoring rolling patterns

Achieving proper density

Cutting asphalt core samples to check for actual density results

Ensuring acceptable quality practices are followed

Quality Control during asphalt production includes:

Properly collecting samples from the trucks immediately following load-out

Monitoring actual mix temperatures at the plant

Verifying liquid asphalt content

Identifying volumetric properties of compacted asphalt specimens and the specific gravity of the asphalt mix

Calculating the gradation of the mix

Quality Control during asphalt paving includes:

Establishing proper rolling patterns to ensure density

Monitoring mix temperatures at the roadway

Monitoring temperatures of the asphalt mat

Calculating tack, dilution, and spread rates

Cutting cores at the roadway for the lab to verify density

Ensuring best paving practices are followed

Quality Assurance is the continued evaluation of planning, design, and the development of 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 asphalt 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
