Preventive maintenance funds can only be expended on the state highway system. Preventive maintenance may include such basic work as seal coats, fog seals, slurry seals, microsurfacing, asphaltic concrete overlays (maximum 1 ½ in thick) plant mix seals (maximum 1 ½ in thick), clean & seal joints in concrete pavement or bridge decks, painting steel bridge structures, recycling asphaltic concrete pavements (maximum 1 ½ in thick), spot concrete pavement repairs, and bridge deck protection. Basic work may include incidental work where necessary, such as pothole repairs, spot base and edge repairs, minor bridge deck and joint repairs, fabric underseals, pavement markings or markers, driveway and turn-out repairs, guardrail upgrading, strip or spot asphaltic concrete pavement level-ups, cold/hot milling or planing, minor widening of travelway (maximum 2 feet each side and only to correct a maintenance problem), and the installation of turn lanes (excluding continuous left turn lanes).

Allocation to Districts

Allocations for the preventive maintenance programs are approved by the commission, with the districts receiving allocations based on the following formula:

  • 80% - lane miles on the State Highway System
  • 10% - vehicle miles traveled per lane mile
  • 10% - lane miles in “substandard” condition, based on Pavement Management Information System (PMIS) Distress Scores between 70 and 89.

The Preventive Maintenance Programs are managed as bank balance programs with eligible projects developed by the districts on an as-needed basis within their allocations. Preventive Maintenance Programs are usually one-year programs with the program funds available for use within four years.
