STRETCHING PAVEMENT LIFE WITH MICRO-SURFACING
Recommendations from a pavement condition and management analysis for the city of Saskatoon, Saskatchewan in 1996 have lead to adoption of a yearly micro-surfacing program for residential streets. The objectives of the program include repairing road failures, ensuring the positive drainage from the pavement surface, and resurfacing the pavement with micro-surfacing. Critical to the success of the program was to emphasize the need for a preventive maintenance approach through micro-surfacing. This pavement preservation treatment was invented in Germany in the 1930s. It involves a mixture of emulsion, aggregate, water and mineral filler that is cold-placed in a thin layer on the road surface, leading to the sealing of surface irregularities and the reduction of moisture infiltration into the road surface. An analysis of the condition of the city's micro-surfaced streets in 2000 revealed that only 1.1% of the total area that had been micro-surfaced experienced failure. The analysis also made recommendations directed at quantifying the overall cost effectiveness of the micro-surfacing program and ensuring that life expectancy of the micro-surfacing treatment is maximized.
