JFC is an American Association of State Highway Transportation Officials (AASHTO) Accredited Testing and Inspection Agency. Laboratory tests are performed in JFC's Materials Testing Lab by qualified and certified laboratory testing technicians, including a WYDOT certified testing technician for aggregate, concrete, and asphalt.

JFC offers a full array of Construction Materials Testing (CMT) and inspection services. Testing services include field-testing, laboratory testing, and specialty testing. Inspection services include foundation preparation, rebar, masonry, high-strength bolting, and specialty inspections such as drilled shafts and pilings.

Field-Testing:

Materials that are field-tested include soils, aggregates, cementitious materials, and bituminous materials. QA/QC testing of soils and aggregates primarily consists of in-place density testing and moisture content to ensure proper compaction of these materials during placement. During laydown, bituminous materials are field-tested for temperature, compacted to help establish rolling speed and patterns, and to ensure proper placement. JFC has the capability to field-test a wide range of cementitious materials: high strength, normal, and lightweight concrete, grout, and mortar. Tests for these materials include slump, total air content, yield, temperature, and unit weight.

Lab-Testing:

Materials tested in our laboratory include soils, aggregates, and cementitious materials. JFC can perform a wide range of laboratory tests on soils to support both our field-testing and Geotechnical Engineering operations. Tests include standard and modified proctor, gradation, wash sieve, Atterberg Limits, permeability, consolidation, swell potential, and many more. Laboratory tests of aggregates include specific gravity and loose unit weight. Cementitious materials are tested in the lab for strength, specific gravity, and mix design. Testing can also be performed on CMU blocks and prisms and soil cement mixtures. Other specialty tests can be arranged by request.
