The paper presents the results of a study of the mechanism for reducing the moisture resistance of sulfur-extended asphalt concrete. It is shown that a decrease in moisture resistance occurs due to the occurrence of chemical and physical processes. At the same time, it was found that during the manufacture of sulfur-bitumen composites, toxic gases H2S and SO2 are formed, which are capable of interacting with a mineral filler, as well as the interaction of sulfur with a mineral powder with the formation of sulfur-containing water-soluble salts, the extraction of which leads to a decrease in the moisture resistance of sulfur-bitumen materials. The change in the rate of leaching of these substances from the composite is due to the physical process caused by the crystallization of sulfur and the formation of a capillary structure, which significantly increases the rate of leaching of calcium and magnesium salts, which are products of dissolution or hydrolytic decomposition of water-soluble products of the interaction of sulfur, H2S and SO2 gases with calcium and magnesium carbonates. The intensity of chemical and physical processes intensifies with an increase in the amount of sulfur in sulfur-bitumen materials.

SummaryBackground/Aim: The purpose of this study was to evaluate compatibility between visual and digital color measurement methods.Material and Methods: The color measurement components of intact natural maxillary right central incisor and left canine teeth of eighty patients were measured with visually shade guide and, digitally, with digital device. The color matchings were performed for each teeth on labial surfaces divided into three regions: cervical, middle and incisal. Ligthness, MLR (M: means middle hue, L designates greener, R designates redder) and chroma levels were assessed for each tooth on divided regions respectively. Measurements were performed by the same and experinced dentist with healthy eyes. The data were analyzed with Kappa and weighted Kappa coefficient (p< 0.05).Results: The compatibility between visual and digital methods did not exist for MLR and chroma. The compatibility between both methods were determined only for ligthness of maxillary central and canine teeth at all regions of labial surfaces.Conclusions: There was compatibility only for ligthness of intact natural teeth at all regions with both methods.
