R-4 <br /> <br />life cycle analysis of the potential rehabilitation approaches, the following is <br />recommended: <br />Fox Street (Section A): <br /> Reconstruct the roadway in the current footprint, creating an even width <br />24’). Construct a pavement section that includes geotextile fabric, 10- <br />inches of aggregate base and 5-inches of bituminous pavement. This <br />rehabilitation method carries an estimated pavement life of 25-years, and <br />because issues with the underlying base materials are addressed the road <br />can be treated with other preventive maintenance (such as mill and <br />overlay) at a future date. <br /> <br />Fox Street (Section B): <br /> Reconstruct the roadway in the current footprint, creating an even width <br />(24’). Construct a pavement section that includes geotextile fabric, 10- <br />inches of aggregate base and 5-inches of bituminous pavement. This <br />rehabilitation method carries an estimated pavement life of 30-years, and <br />because issues with the underlying base materials are addressed the road <br />can be treated with other preventive maintenance (such as mill and <br />overlay) at a future date. <br /> Reconstructing only the pavement structure, and including other <br />improvements measuring less than a linear length of twenty-percent <br />(20%) of the total roadway length, allows this method to adhere to the <br />MSAS definition for Roadway Reconditioning. This is similar to the <br />rehabilitation currently being performed on Watertown Road. <br /> <br />Fox Street (Section C): <br /> Mill 6’’ and overlay 3’’. This rehabilitation method carries an estimated <br />12-15 year design life. <br /> <br />Pavement Structure Reconstruction (Sections A & B): <br />Geotechnical investigation revealed that the three sections have vastly different <br />amounts of underlying bituminous and aggregate base. The borings also <br />indicated a number of places where organic materials exist that create a <br />challenge for roadway reconstruction. Section A exhibits relatively consistent <br />pavement thicknesses built on poor or degraded aggregate base. The absence of <br />a clear layer of aggregate base removes Reclaiming and Paving as a viable <br />option for Section A. Section B is largely the same as Section A, with
