Similar to Microsurfacing, a TopShell overlay can be used to help municipalities, HOA’s and private business owners bridge the gap between continually paying for petroleum-based preventative maintenance products such as sealcoating and microsurfacing or and the expensive process of milling/filling the existing asphalt. A single application of TopShell will extend the service life, increase friction, and improve the appearance of the pavement surface. TopShell saves the underlying investment from oxidation, water, chemicals, and traffic.
