Micro surfacing (also referred to as 'micro asphalt') is a treatment laid over the top of the existing surface designed to seal, protect, and extend the life of asphalt surfaces. The application involves a self-priming paver, which applies polymer modified emulsion bond coat directly in front of the paving screen where an ultra-thin overlay of specialized hot mix asphalt is placed.
Micro-surfacing not only improves the durability of the street surface compared to typical track coats but reduces life-cycle costs by 25 to 45% and adds 6 to 8 years of street lift when applied.
When should Micro Surfacing be used?
Micro surfacing is used on roads that exhibit low severity cracking, raveling, and oxidation. It’s Ideal for sealing and filling voids in the existing surface while improving skid numbers. It can also be used for correcting mild rutting without additional crowning or surface buildup.
Why can’t every street be Micro Surfaced?
Once a street reaches a certain point of deterioration Micro Surfacing will not work and only a full reconstruction is an option.
