Micro Surfacing. Micro-surfacing is one of the fastest growing asphalt maintenance tools utilized across Western Canada. Micro-surfacing is a mixture of polymer modified asphalt emulsion, manufactured aggregate, portland cement, water and liquid additives. The mixture is proportioned according to specifications and laboratory mix design.
Micro surfacing involves the placement of a polymer-modified slurry mixture consisting of dense graded aggregates, asphalt emulsion binder, mineral fillers, additives and water onto the existing pavement. Micro surfacing applications typically have a surface life of up to 10 years or longer, and they help improve skid resistance.
Micro surfacing shall consist of mixing a polymer modified cationic quickset emulsion, aggregate, mineral filler, set-control additives, and water and spreading the mixture on a pavement surface where shown on the plans, in conformance with the provisions in these special provisions, and as directed by the Engineer.
Tashiminimac. Tashiminimac is compact yet powerful micro-surfacing / slurry seal / Cold-mix asphalt paver developed for working in areas with limited access like hilly terrains and city roads. It can double up as a compact road maintenance machinery for highways and toll roads where normal road repairs like pothole filling, crack sealing ...
Multi. Micro-surfacing is the application of a special coating to the top layer of asphalt. It is 10 - 15 mm thick and creates a protective layer that preserves the underlying pavement by preventing oxidization and moisture penetration. It is a cost-effective treatment that prolongs the life of the road and helps to avoid costly and disruptive ...
Microsurfacing is a design mixture of polymer-modified emulsified asphalt, mineral aggregate, mineral filler, water, and other additives proportioned, mixed, and uniformly spread over a properly prepared surface. The mixture is made by a specialized machine and placed on a continuous basis by mixing the materials simultaneously in a pug mill.
A B. (PCI of 70 or greater) Micro surfacing is a surface treatment designed to extend the life of asphalt pavements in good condition by providing skid resistance, restricting moisture intrusion, protecting the structure from further oxidation and raveling, and restoring a uniform black appearance. It is the most economical choice when leveling ...
