The asphalt pavement on Longmere Drive is in poor condition and in need of
repair. Per the City’s pavement rating software, 9 out of the 10 sections on
Longmere Drive have a Pavement Condition Index (PCI) of 27 or less. Based on
these PCI ratings, the majority of Longmere Drive can be classified as either a
"Poor to Very Poor" condition or as a "Failed" condition. Per City records, the
last time that Longmere Drive had major street work performed on it was 23 years
ago in the summer of 1986. A process called In-Place Cold Recycling was used to
restore the pavement to good condition at that time. Cold In-Place Recycling (CIPR)
is an on-grade method of pavement rehabilitation that consists of milling the
existing asphalt concrete pavement to a depth between 2 to 4 inches; mixing the
cold milled material with emulsified recycling agent and other additives as
needed; spreading and compacting the recycled mixture; and overlaying the
recycled surface with a new layer of hot mix asphalt (HMA). Foamed asphalt can
be used as a recycling agent instead of asphalt emulsion, but fine aggregates
may need to be added to the recycled mixture. Based on recent pavement cores
taken on Longmere Drive, the in-place cold recycled layer of the asphalt
pavement has lost cohesion which reduces the overall strength of the asphalt and
also allows water to penetrate the subbase easier causing the pavement to
deteriorate at a faster rate. On top of this, the asphalt pavement’s surface
course is due for resurfacing based on a 15 to 20 year life span for surface
course asphalt.
Based on this data and other traffic volume factors, it was determined that
reconstructing the pavement on Longmere Drive was a better option than
resurfacing since outside funding was secured by the City. Longmere Drive is
functionally classified as a collector street which means that it has a higher
traffic volume since it collects traffic from several local (residential)
streets. Pavement reconstruction will provide the strength and integrity needed
in an asphalt pavement to handle the larger traffic volume on this street.
This project is being funded using Ohio Public Works Commission (OPWC) funds
along with funds from the City’s Annual Street Program. The additional OPWC
funds will allow the City to replace the asphalt pavement at a cost similar to
that of a typical mill and resurface project.
