What are the different types of soil-cement
materials?
For base material, is there a cost
advantage in using a cement-treated base over an unbound graded
aggregate base?
How soon can a newly constructed
cement-stabilized roadway base—whether a cement-treated base
(CTB) or a full-depth reclamation (FDR) base—be opened to
traffic?
Is it less expensive to rehabilitate
an entire roadway through FDR using cement rather than removing
and replacing the roadway?
Which product is better—portland
cement or hydrated lime—in stabilizing clay soils?
I've heard that improperly constructed soil-cement
bases have a tendency to crack due to shrinkage. Is there a process
that can be used to help minimize this problem?
Is there a test procedure to determine
how much portland cement to use for a given FDR pavement project?
How exactly does a pugmill work
to blend materials together for CTB?
What is micro-cracking (or pre-cracking)
of cement-treated bases?
How do you collect and prepare
samples for FDR projects?
How does cement slurry compare with
lime slurry?
Because there is no noticeable color
change, how can I tell how deep my roadway materials were treated
with cement?
Should the acceptance criteria
of completed soil-cement be based on compressive or flexural strength
test results of in-place cores or beams?
