"I’m interested in anything that will save the town and residents money"

During the hot-in-place paving process — developed in the late 1970s — a special machine moves over the pavement, melting, scratching and lifting it up. Then, the collected asphalt is mixed with new oil and materials and redistributed over the road. 
Another rig rolls over the new surface, packing it down and smoothing it. Cars trailing the rolling machine can drive on the surface without having to wait for it to cool. 
The crew will work on one lane a day, so the road will not have to close. Still, residents should expect delays. 
The hot-in-place method is cleaner in part because crews do not have to tear up the road, which produces dust. And because the asphalt does not have to be hauled anywhere, there are fewer trucks involved. 
According to Department of Public Works Director Robert Cantoreggi, the hot-in-place method will save the town almost half of what it would cost to do normal road reconstruction.

The process described is being used on the stretch of Washington St from South St to the Bellingham line as noted in the earlier road construction alert.
