Abstract:A global chemical stabilization design is recently
adopted by the Ohio Department of Transportation
(ODOT). This produces performance and economic
benefits in providing pavement with a rugged base
supporting. Given the large quantities of lime required
for implementing a global soil stabilization, it is the
interest of transportation agencies if inexpensive sources
of soil stabilizer can be utilized for subgrade
stabilization. One potential resource can be utilized is
the lime sludge produced from drinking water plants.
The purpose of this study is to conduct pilot experiments
to assess the feasibility of lime sludge for subgrade
stabilization. The study focused on the feasibility of
using lime sludge as a substitute of regular lime used in
road construction, design issues such as method of lime
sludge introduction, the optimum content of lime sludge
and the long term performance, etc. Special local issues
such as freezing-thawing durability were investigated for
implementing in Ohio.
