Micro-surfacing The application of a cold mix of dense-graded aggregate, polymer modified asphalt emulsion, water, and mineral fillers. Capable of filling wheel ruts up to 40mm deep when the pavement has stabilized and is not subject to plastic deformation. Benefits: improves surface friction slows surface ravelling and seals small cracks

The extremely cold temperatures, excessive precipitation, salting, and strain from winter tires can cause your asphalt to severely deteriorate and crack under the pressure. Cracks need to be repaired right away or else they can expand and become costlier in the long run.

30 4.6. Chip seal:- Also known as a surface treatment, a chip seal is a layer of asphalt emulsion covered by a layer of single-sized aggregate. Timing of the construction, and the weather during construction, have major influences upon the success or failure of a chip seal. Chip seals will be discussed in more detail later in this chapter.

Slurry seal is a cold mix coating consisting of fine crushed aggregate, emulsified asphalt, additives, and water applied to roadways. Emulsion serves as a binder to hold the aggregate together and to adhere to the roadway. Slurry seal is very economical and extends the life of pavement up to 7 years.

Micro-Surfacing Benefits Micro-surfacing seals small cracks and surface imperfections, waterproofs the surface, and protects the pavement structure of both asphalt and concrete pavements. The high quality, crushed aggregate improves skid resistance. The mat provides an attractive, smooth black surface which aids in lane delineation.

Remove the surface seal After the injected epoxy has cured, the surface seal should be removed by grinding or other means as appropriate. Alternative procedure For massive structures, an alternate procedure consists of drilling a series of holes [usually 7/8 to 4-in. (20 to 100-mm) diameter] that intercepts the crack at a number of locations.

Developments in Microsurfacing. 1. BACKGROUND. During the late 1960's and early 1970's German scientists began experimenting with emulsion/aggregate mixes to find a way to use stable, thicker applications which could be applied in narrow courses to fill wheel ruts, without destroying expensive road marking lines on the autobahns.
