“Micro-surfacing has proven effective in filling ruts, reducing the amount of original rutting by 40%, and substantially increasing the friction characteristics of the pavement.” – Transportation Research Record No. 1392
Effective Pavement Preservation
Micro-surfacing is an effective preventive maintenance application that seals and waterproofs the surface while correcting minor defects, filling non-working ruts and improving skid resistance and appearance. The thin surface is an excellent choice for city streets and airports as well as high traffic volume roads. The high-performance surface treatment is a mixture of fine dense-graded aggregate, polymer modified asphalt emulsion, water, mineral fillers and additives. The aggregate is 100% crushed, and meets stringent requirements for clay content, soundness and abrasion. The components are mixed and placed on the road using a single machine. Micro-surfacing can be placed on both asphalt and concrete pavements.
The system is formulated with polymers and chemistry for a very quick cure and traffic return, as well as durability on high traffic pavements. Since micro-surfacing cures quickly, it can be placed thicker than other emulsion surface treatments and used to fill ruts and for minor re-profiling. Special equipment allows the filling of ruts up to 1.5 inches. The chemically-controlled break also makes microsurfacing ideal for night paving. Typically, traffic can be returned within one hour.
Type II uses a crushed, high quality aggregate and is generally used for general street re-surfacing and medium volume highways. Type III, formulated with a coarser aggregate, is used on freeways, high speed roads, industrial applications, runways and where rut-filling or re-profiling is required.
