HOPKINTON – City Manager Norman Khumalo and Director of Public Works John Westerling are pleased to share a video highlighting the completion of several paving projects in Hopkinton using a new environmentally friendly paving process .
Over the past few weeks, the town of Hopkinton has overseen a new city-wide paving process known as cold-in-place recycling. This new method was initiated and led by Director Westerling and Director of Freeways Mike Mansir, both of whom were instrumental in bringing this method to Hopkinton. Mansir, who spent over two years researching the method and visiting other communities that used the cold-in-place method, oversaw all day-to-day operations of the paving process.
The cold-in-place recycling method takes the pavement of an old or failing pavement and recycles and rejuvenates that existing pavement into a new pavement. The process consists of a chain of equipment that grinds the existing pavement and adds powdered cement and liquid asphalt. Once the old pavement has been crushed, the powdered cement and liquid asphalt mixed, the mixture is then spread over the pavements using compacted rollers. Following this process, commuters can drive on the road immediately, unlike traditional asphalt concrete which takes hours to set before it can be driven.
The cold in-place recycling process takes about five hours per lane, unlike the traditional paving process which takes weeks to complete the asphalt removal and the laying of a base layer of paving. Typically, the entire traditional road repaving process can take over a month versus a day or two to complete the cooling-in-place process.
“There are many benefits to the cold in-place recycling process, including reduced traffic disruption and inconvenience commuters can experience due to traffic delays and detours,” said Westerling Director. “Tax-wise, the process is also more cost-effective for the city, as it provides savings of over 20% compared to other traditional methods of pavement reconstruction. “
To date, the Town of Hopkinton has repaved portions of Legacy Farms Road from Cedar Streets to Wilson Streets, Edge Hill Road, Stoney Brook Road from Saddle Hill Road to Wedgewood Drive, Cunningham Street, parts of the School Street from West Main Street to West Street. Elm Street and the Upton City Line, and West Main Street from Oakhurst Road to School Street.
Right now, the City is in the last step of the process, which is adding the wearing course, another inch and a half of asphalt and painting the lines of the road.
“With this new method of replacing our roads, we are streamlining a process that in the past took a long time and had a significant impact on the travel of members of our community,” said General Manager Khumalo. “We would like to thank John and Mike for being instrumental in bringing cold in situ recycling to the town of Hopkinton and for their continued leadership and dedicated efforts throughout the project. “
