Asphalt Testing and Inspection

Stork Materials Technology meets this challenge head-on, offering full-service asphalt design and testing services, performed by highly-qualified asphalt testing engineers and backed by the documentation you need to ensure quality asphalt production and installation.

Stork's asphalt testing services group evaluates asphalt binders, asphalt mixtures and other derivatives of asphalt geared for use in the construction industry. This group maintains a high level of proficiency through technician experience, certifications and laboratory accreditations (A2LA and AASHTO).

Asphalt Binders (Oils) We perform a wide variety of physical tests as part of third-party evaluation, QC/QA testing or material specification. These tests include such things as softening points, viscosity tests, and other physical tests.

Performance Grade Evaluation Stork is fully accredited by AASHTO to verify and determine asphalt binder performance grades.

Asphalt Emulsions and Cutbacks We routinely test asphalt emulsions and cutbacks to verify compliance with specifications.

Hot Mix Asphalt Stork engineers design and evaluate hot mix asphalt using Superpave, Marshall (P-401), and Texas Gyratory (TxDOT) procedures.

Aggregate Testing Since most pavements consist of 95% aggregates, Stork engages in the testing of these materials. In addition to routine tests, we specialize in those hard to find procedures, such as Polish values, Soundness, and the Los Angeles Abrasion test.

Asphalt Field Services We provide personnel and equipment to evaluate the production and placement of asphalt paving. This may include a mobile laboratory, or we may simply provide personnel to inspect and assist with placement activities. This service fulfills a valuable role in the QC process.
