Bituminous
|
The recent increased emphasis on
quality in the asphalt paving industry by federal,
state, and local government agencies has resulted in
many states adopting a new system of quality control of
bituminous materials in the field. Under this new
system, the contractor is now responsible for duties
previously conducted by agency field and agency plant
inspectors – making the tasks of developing
qualified personnel and implementing the necessary
laboratory facilities increasingly complicated. SK
Geotechnical assists in determining if plant-produced
bituminous mixtures meet the project
specifications.

Field Testing
Facilities
|
We have two mobile field testing
laboratories for quality control testing of bituminous
mixtures along with our in-house bituminous and aggregate
trial mix laboratory. This laboratory is capable of
conducting the following bituminous related tests.
- Aggregate quality testing (percent crushed, spall,
shale, etc.)
- Asphalt extraction – American Society for Testing and Materials (ASTM) D 2172
- Extracted aggregate gradations – American
Association of State Highway and Transportation
Officials (AASHTO) T30
- Marshall density testing – ASTM D 2726
- Marshall stability and flow – ASTM D 1559,
AASHTO T245
- Maximum theoretical (Rice) specific gravity –
ASTM D 2041
- Thickness and density of pavement cores –
ASTM D 3549 and ASTM D 2726
- Virgin aggregate gradations – ASTM C 13

A Commitment to Quality
|
Along with our skills and experience
in pavement research, design, and materials testing, we
have a fully implemented quality assurance program. Our
highly trained laboratory and field staff are provided
with modern calibrated equipment. Our test instruments
are regularly checked and calibrated, using equipment
traceable to the National Institute of Standards and
Technology (formerly the National Bureau of
Standards).
Our laboratory meets the requirements of ASTM D 3666, "Evaluating and Qualifying Agencies Testing and Inspecting Bituminous Paving Materials."
