It discusses the expected life of asphalt and how this is prolonged with regular maintenance. It discusses the specific mechanisms by which asphalt deteriorates such as poor drainage, excessive loading, weathering, poor design, poor construction and fuel spills. It contains specific maintenance types associated with a numerical rating system and outlines the following maintenance strategies: Appearance, Worst First, Bang for the Buck, Operational and Political. The importance of identifying and following triggers in planning maintenance work is also explained as is Tort liability. Specific maintenance types included in the text are Asphalt crack sealing, Fog and Asphalt Seal Coats, Sand Seal Coats, Slurry Seal Coats, Chips Seals, Heating/Infrared and Micro Surfacing.
