Street Paving Information – Updated weekly (Updated March 21st, 2020)

Update as of March 21, 2020:

Contracts have been signed for this Summer’s paving projects.  Very soon paving will commence of the net series of streets. As soon as we have a schedule I will post it here.


As Alderman in Nashua we have been asked why it takes so long to pave a street.  Nashua is in the early stages of a multi-million, multi-year project to bring Nashua’s street back to where they should be.  This year we are paving some 31 miles of city streets and the work this year is being done by three different paving companies.  I will briefly try to explain the process and give you some insight into why it takes so long to complete a road.

First:  The City hired a firm to grade each and every city street as to its need to be repaved.  The BPW is utilizing this list (available on their website) to prioritize the paving.  Some streets can have their top layer scanned off and then a new base coat and final coat applied.  Some streets are so bad they need to be reclaimed by taking all the tar off and regrading the street, followed by a new base coat and then final coat (expensive).  Some streets can just have some crack sealing done for now until they mover up the list.

Second:  When the companies come into Nashua with their grinding machines, they will grind down all the streets on their contract first and then move that equipment to another city.  This is the most cost-effective process for these companies doing multiple streets. These companies will not bid to do each street individually as it is not cost-effective nor can they meet all their other contract demands.

Third: The next step in the process is to have a sub-contractor come in and raise all the manhole covers, drain covers, etc. to get them ready for the new base coat.  They must complete their work before the next step.

Forth: The paving company returns with paving equipment and puts down the base coat.  This base coat must cure for a few days before any final coat can be applied.

Fifth:  The paving company returns again and puts down the final road surface.  Temporary lane markers are put down as lane marker paints cannot be put on for several days or they won’t take.

As you can see, there is a lot of work to pave this many streets.  Also, when it rains hard the companies cannot work which slows the process down.  We have had a lot of rainy days this year and the companies are trying to do the best they can and finish their work this Summer.
