Portland
Cement Concrete, Physical Tests, and Special Projects
Responsible for:
- Conducting tests on Portland cement, Portland cement
concrete, curing compounds, joint sealers, concrete and clay pipe, metal
products and related items, and developing materials specifications.
- Providing technical guidance and coordination for
precast/prestressed concrete fabrication and inspection of steel bridge
fabrication.
- Pavement friction testing, pavement deflection testing,

and studies, and obtaining pavement core samples.
- Conducting foundation investigations and monitoring
embankment foundations during construction.
Geotechnical
Geotechnical Section performs geotechnical investigation
and providing recommendation for the design and construction of roadway
and structures for all NDOR projects as needed and helps in other public
projects if requested. This section is also responsible for the review
of geotechnical reports prepared by a geotechnical consultant for NDOR
projects.
The Geotechnical Section consists of three units and
their responsibilities are:
- Bridge Foundation Unit:

as needed and county bridge foundations when requested.
- Design appropriate foundation systems.
- Review state and county bridge foundations plans.
- Perform on site integrity and capacity tests for foundation systems.
- Update historical information.
- Soil Survey Unit:
- Investigate and define subsurface materials and conditions for
roadway design.
- Predict the probable stability of cut slopes.
- Creat th 2K plan sheets.
- Soil Mechanics Unit:
- Perform subsurface investgations, install analyze field instrumentation
during embankment construction.
- Perform geotechnical analysis of embankments, MSE Walls and culverts,
to evaluate settlement magnitude, settlement time, slope stability
and foundation soil suitability.
- Perform and evaluate soil mechanic testing.
- Provide geotechnical support during construction.
Flexible
Pavement, Chemicals, and Aggregates
