A major new road scheme is being proposed. A preliminary
study has revealed that there are pockets of clay and peat
as well as firm rocky ground along the route.
You are a highway consultant instructed by a local authority
to advise on which tests are needed for the likely ground
conditions associated with this scheme.
You are aware that the value of soils testing is not always fully
appreciated by decision makers looking to cut costs. You will
need to point out the risks of failing to identify any ground
problems before contracts are let and the works start on site.
TASK
Prepare a paper of investigating the requirements above.
• Explain the most likely soil types that you expect to
encounter and the most appropriate soils analysis tests that
would be used for these
• Examine the use of these tests and the cost implications of
these
• Evaluate the risks associated with each of the ground types
that you expect to encounter and the possible
consequences for the design and construction of the road
