Design,Building,and Testing of A Portable Polishing Machine for Pavement Evaluation.

摘要

A new portable polishing machine for rapidly polishing a pavement surface to an equilibrium is described. The machine has a built in friction measuring device to indicate the skid resistance while polishing. Initial polishing data is presented by comparing equilibrium coefficients of friction. Even though the correlation of the two different polishing machines is not one-to-one,polishing and friction measuring tests show that the portable polishing machine is acceptable for both tasks.
