| This study is a fundamental research for developing self-deicing function of snow-melting asphalt concrete for roadway pavement. The objective of this study is to develop technology of making self-snow-melting asphalt pavement and evaluate properties of the asphalt concrete containing deicers. Asphalt concrete with deicers and CRM was produced by dry process. The $alpha$-deicer, CRM and F-deicer were used for sand asphalt mixtures of thin-layer pavement on the existing pavement. The $alpha$-deicer, $eta$-deicer, CRM A, CRM B and C were used for 13mm dense-graded mixtures on surface course. Penetration grade of 60-80 asphalt was used for asphalt mixtures. Marshall mix-design, indirect tensile strength, freezing and thawing test, analysis of extracted water were carried out to evaluate performance of self deicing function of asphalt mixtures. The study result showed that snow-melting asphalt mixtures had not only good mechanical characteristics and good snow-melting function, but also chemically safe in environmental point of view. |
