Abstract

To achieve proper bonding between the pavement layers it is necessary to spread the precise amount of tack coat. In several laboratory tests, effectiveness of a newly designed device to control the tack coat dosage applied on site is studied, in which the most influential variables are surface macro-texture and amount of tack coat applied, with a negligible influence of the emulsion type. According to the results obtained, the geotextile absorbs higher percentages of emulsion for samples of bituminous mixtures with lower surface macro-texture values, e.g. AC16D, while the lowest percentages of absorbed emulsion are obtained for samples with higher surface macro-texture values, e.g. BBTM11A. The emulsion percentage absorbed by the geotextile is directly related with the quantity of emulsion in charge of the bond between layers.
