Integrated models like the Anglo-Saxon Model" are more favorable to warmer climates and the Anglo-Saxon countries are more able to integrate routine and periodic maintenance, while it is quite difficult to integrate the routine and periodic maintenance in the northern climates. It easy to understand that if winter and cold weather occurs for over 6-8 months of the year, then the re-surfacing component of periodic maintenance can be efficiently managed and arranged by the road authorities by separate agreements. For example, due to the limited time of warm weather the resurfacing aspects can be more effectively managed and controlled when done separately. In addition, the Northern markets are quite small, have very few suppliers, and competition in these activities is limited.
