The objective of the paper is to present the results of an extensive experimental work carried out in field weather conditions to study the ageing effects on skid resistance of a bituminous mixture for road pavement wearing course. A set of prismatic roller compacted specimens were aged using two laboratory ageing methodologies: 1) short- and long-term oven ageing (LTOA); 2) TEcnico accelerated AGEing methodology (TEAGE); 3) and an experimental section was exposed to real climatic conditions (Field), as reference. A bituminous mixture for wearing courses with a maximum aggregate size of 14 mm and a neat bitumen 35/50 was evaluated. To assess the evolution of surface characteristics with the environmental effects, both micro- and macrotexture properties were evaluated in laboratory and in the field over the time using the Pendulum test value (PTV) and mean texture depth. Measurements were performed before the ageing starts and after six months until the specimens reach the pretended age. In terms of micro-texture was possible to verify that no significant impact was observed for LTOA ageing method. However, the evaluation performed on the samples aged under real conditions and using the TEAGE method showed considerable increases in PTV in first 12 months. After this period, the results presented a tendency to a constant P TV. After 18 months, the samples under real environmental conditions showed a slightly decrease of PTV. This decrease can be associated with the removal of the aged film of bitumen that covers the aggregates by the action of the rainfall.
