His department has filed 1,762 potholes as of Tuesday, Nau told Selectmen.
Selectman Chair Dennis Giombetti said it is not just a Framingham problem but a Massachusetts problem.
Route 9, a state maintained road, has numerous potholes.
Nau said this department has aggressively been filling pot holes in Framingham, since Feb. 18.
Selectman Laurie Lee said Potter Road was terrible and asked if school roads are given priority.
Nau said his department starts with the main roads, and also tries to respond to resident's calls. He said Potter Road is on his list.
Warren Road, which also has heavy school traffic due to McCarthy Elementary and Fuller Middle, was littered with more than a dozen potholes on Monday morning but by Monday afternoon Framingham DPW had filled them.
Potholes form when water causes pavement to expand and contract.
Water enters into pavement and they it freezes. When it freezes, it takes up more space under the pavement, and the pavement expands and cracks. Then when ice melts, the pavement contracts and leaves gaps or voids in the surface under the pavement, where water can get in and be trapped. If the water freezes and thaws over and over, the pavement will weaken and continue cracking. As the weight of cars and trucks pass over the weak spot in the road, pieces of the roadway material weaken, which will cause the material to be displaced or broken down from the weight, creating the pothole.
