大跨径钢桥面浇注式沥青混凝土铺装应用研究

Application Study of Gussasphalt Concrete on Pavement of Long Span Steel Deck

浇注式沥青混凝土具有优良的防水、抗老化性能、抗疲劳性能以及对钢桥面板优良的追从性,其在国外应用于桥面铺装已有多年的历史,取得了丰富的经验。本文从浇注式沥青混凝土的材料组成设计、粘结层强度、混合料特性与路用性能、浇注式沥青混合料的生产与摊铺等方面出发,全面系统地研究了大跨径钢桥面浇注式沥青混凝土铺装技术。

The performances of the gussasphalt are fine protection, fatigue resistance and bonding with steel deck. in properties, such as water It has been used in steel deck pavement for many years abroad, so a lot of experiences have been obtained. In this paper, the technology of application of gussasphalt concrete on steel deck is introduced, such as material composing design, mixture design, strength of adhesive layer, mixture material properties and service performances, production and sprending of gussasphalt concrete.
