DEVELOPING INNOVATIONS IN THIN, VERY THIN, AND ULTRATHIN OVERLAYS: THE MONTREAL EXPERIENCE

In 1988 the executive committee of the city of Montreal approved a policy proposal concerning the management of Montreal's network of roads and sidewalks. The proposal covered a 10-year span and included a funding plan that earmarked a total of $350 million for this purpose. Among the many clauses of that policy, two statements were to help the Montreal Public Works Department step out in the field of innovation. One statement set out maintenance priorities: first, conservation; second, prevention; and third, rehabilitation. The second statement directed the department to study, evaluate, and implement new treatments for roads, especially in the category of conservative maintenance. After resolving many issues through discussions and meetings, the public works department believed it could proceed with various calls for proposals. In 1991 the call was for very thin overlays (15 to 30 mm); in 1992 the call was for ultrathin overlays (less than 1.5 mm); and the department is now in the process of a similar call for proposals for thin overlays (30 to 50 mm). This paper provides further details on Montreal's experience in pavement management with thin, very thin, and ultrathin overlays.
