 · This is due to the intergrinding of the limestone with the cement clinker resulting in the softer limestone being ground more finely than the cement. A "scaffolding" effect has also been observed where earlyage hydration product precipitate on the smaller limestone particles. In combination, the finer grind, improved particle packing, and scaffolding effect in the PLC systems results in ...

Milling is the process by which old and damaged pavement is removed to prepare the surface for new overlay. Also called grinding or cold planing, milling removes the high points in an existing pavement to produce a relatively smooth surface. Milling machines fitted with automatic grade controls can restore both longitudinal and transverse grades, all while removing damage from rutting, bumps ...
