Going on pothole patrol in Goffstown
A motorist makes her way slowly through the frost heaves and potholes on Center Road in Hillsborough Monday. It appears this spring will have an abundance of the annual road hazards.
GOFFSTOWN — Winter's weather brings spring's bad roads. So for the next few weeks, Goffstown will be conducting its seasonal spring repair of potholes.
The town uses the "mill and fill" method, where the pothole and some surrounding pavement is milled out and a permanent hot pavement patch is installed. This is more effective and longer-lasting than the cold patch used during winter.
"By milling the hole you provide a solid square edge for the new asphalt to bond to. Also, you can make sure to remove all old cracked asphalt and mill up some of the failed saturated base material under the pavement," said Carl L. Quiram, Goffstown's director of public works. "Once clean new gravel is compacted into the trench and new asphalt laid you have a much more durable repair."
While the mill and fill method is more expensive than just filling the hole, it is more cost-effective.
"The up front repair is more expensive because you are enlarging the patch, which means more material and using the additional equipment. However, given that a proper mill and fill repair should last several seasons ... it is much less expensive in the long run," said Quiram, adding that the town has been using the process for at least four years.
According to the 2014 budget, the town spent about $26,000 in 2013 for crack sealing.
To report a pothole in your neighborhood, call the DPW at 497-8990, ext. 200, and leave a message with the location of the nearest house or business address and a contact number. You can also go to goffstown.com and submit an online work order request. Work will be scheduled from 7 a.m. to 4:30 p.m. Tuesday through Friday.
The DPW will first focus on main roads then move to side roads as needed.
The town's load and weight restrictions, which have been in effect the past few weeks, were lifted Tuesday.
The load limit policy is done during the spring thaw to prevent roadway damage and to protect the town's infrastructure investment. The town had placed restrictions on 50 town roads beginning March 20 and residents were asked to coordinate deliveries from 10- to 22-ton trucks, except for emergencies.
