Micro Surfacing - International Slurry Surfacing Association

Micro Surfacing creates a new, stable surface that is resistant to rutting and shoving in summer and to cracking in winter. Applied to both asphalt and Portland cement surfaces (usually preceded by a tack coat on ), Micro Surfacing is often used to restore a skid-resistant surface to slick bridge decking with minimum added dead weight.


Micro-Surfacing application is plastic deformation or pushed up asphalt on the surface. Here is an example where the surface lift has pushed up at the edge line. Once again the Micro-Surfacing material does a good job of filling in any low spots in the surface but it is not very effective when used to correct high areas in the road.
