ABSTRACT
The aim of this paper is to analyse the efficiency of two treatment techniques for pavement surface characteristics: skid resistance and longitudinal roughness. For this purpose, the paper describes a case study of a motorway surface to which the following two treatments were applied: a bituminous surface treatment and abrasive shot-blasting process. The quality control performed before and after treatment applications enabled to draw conclusions about the efficiency of these techniques. Based on the data collected from pavement surface monitoring, it was concluded double micro-surfacing was a more effective and durable technique for simultaneously recovering skid resistance and longitudinal roughness.
