Microsurfacing consists of mixture of modified bitumen emulsion, well graded mineral aggregate, water, filler and additive proportioned, mixed and uniformly spread over a properly prepared surface. The finally laid Microsurfacing shall have a homogeneous mat, adhere firmly to the prepared surface and provide friction resistant surface texture throughout its service life. The mix is a quick setting system i.e., it is able to receive traffic within 1-2 hours of its laying. It is applied on an existing pavement surface which is structurally sound but is showing the signs of functional distress such as loss riding quality, cracking and polishing. As a surface treatment, micro-surfacing imparts protection to the underlying pavement and provides renewed surface.
