NORTH MECHANIC STREET IMPROVED BY CITY OF CUMBERLAND

North Mechanic Street, a heavily traveled, connecting street, from West US 40 into downtown, has been rehabilitated by the City of Cumberland, Maryland. The contract improvements extended from Bedford Street to North Center Street and included widening and total replacement of roadway surfacing, curbs, sidewalks and storm drains. Contract pavement sections varied in width from 22 to 30 feet and consisted of 5" of CR6 crusher run stone base, two 3" courses of hot mix asphalt SHA BI base mix and two 1-1/2" courses of hot mix asphalt SHA SN surface mix. The total asphalt tonnage for the project was approximately 1,900 tons of SN surface mix and 3,800 tons of BI base mix. Moisture content of the subgrade soils was considered marginal and a potential problem. A geotextile fabric was place on the subgrade for stabilization purposes. The use of the stabilization fabric was effective in solving the problem and less expensive than removal and replacement of the questionable subgrade material. It was determined that an existing sewer trench withing the pavement section of North Mechanic Street had been backfilled with unsuitable material. The contract included removal and replacement of this material. (Author)
