INFORMATION

Project Limits:

The proposed improvements for this project will take place on Centre Road – State Route 141 from 530' South of Lancaster Pike – State Route 48 to 1,225' North of Kennett Pike – State Route 52.

Project Need

The 30 year existing concrete pavement within the limits of this project is deteriorating as a result of ASR (Alkali Silica Reaction). Definition: Silica which is found in aggregate when introduced to moisture is broken down by the alkalis in the cement which produces an expansive gel. The expanding gel creates tensile force that causes concrete to crack which allows additional moisture to enter producing additional gel. The end result is that the concrete fails or disintegrates as we are experiencing on Centre Road.

Project Overview:

The scope of work for this project includes the replacement of the existing concrete pavement including the Kennett Pike – Route 52 interchange ramps, concrete curb, drainage, and guardrail replacement.

Project Schedule:

Construction is anticipated to begin in October 2017

Construction is anticipated to be completed by Spring 2019
