aggregate products for several years and continue to meet the City’s needs. As
local vendors the close proximity of their facilities has saved the City valuable
time when completing daily projects. In the early spring and late fall the only
plant open is often Brox in Dracut, MA. The asphalt we are seeking approval for
is used for filling pot holes, our mill and fill program, fill around catch basins and
for small paving projects done by the Street Department. This is not part of the
paving program.
