The ball should be neither hard nor soft and should break easily after applying a little finger pressure. What remains after the ball is broken should be granular and not resemble fine powder. In the case of dry granulation, there are several measures that can be applied to the mill or shear mixer to detect the end point.

Milling also helps address a number of other issues. Pavement Height and Drainage . Another solution to restore a pavement's surface is to apply an overlay. Because the overlay is a new layer applied to the existing asphalt, each time this procedure is performed it raises the height of the pavement.

A powder's mesh size can at times be somewhat confusing. A -6 mesh powder contains particles that pass through a 6 mesh screen. A -6 mesh powder has particles that measure less than 3360 microns. A powder that is -325 mesh has particles that measure less than 44 micron. As you can see, the larger the mesh number the smaller the particle size ...
