Micro-Surfacing Projects Conducted by the British Columbia Ministry of Transportation 1998-2004
In 1998 the Ministry of Transportation of British Columbia (BCMoT) initiated an extensive field evaluation of micro-surfacing technology. Between 1998 and 2004, thirteen micro-surfacing sites with a total area of 381,000 sq. m were constructed. The program selected a range of sites in various climatic conditions such as the cold Mackenzie region, the hot and semi-arid Okanagan Valley, and the high altitudes of the Coquihalla Highway. The micro-surfacing was assessed for its suitability to withstand intense winter maintenance operations. It was installed either on major high traffic volume highways or in the urban environment. Micro-surfacing was also evaluated for its effectiveness of surfacing Portland cement concrete substrates. Test results from the micro-surfacing program are very encouraging and educational as they have defined the advantages and limiations of the process. Micro-surfacing has been established by the BCMoT as a suitable technique to supplement dusty seal-coating operations in residential areas, for use in rut filling, and as a preventive maintenance to rehabilitate deteriorating asphalt pavement surfaces. An in-house technique for the treatment of concrete bridge decks with micro-surfacing was also developed. Project information indicates that micro-surfacing is a practical and economical process which is cost competitive with graded aggregate seal applications.
