Utilizing a spray paver, agencies can now specify a higher quality polymerized tack coat applied at application rates of 4 to 6 times higher than traditional methods. This is achieved using a spray paver which combines the distributor and paver equipment into one machine, thus eliminating tracking away of the tack coat by construction vehicles.
