Deck concrete pavement

This paper introduces technologies of epoxy asphalt concrete used in steel deck pavement concerning properties of materials and mixtures, design of mixture ratio, production and laying.

本文从材料、混合料性能、配合比设计、生产和摊铺等方面介绍了环氧沥青混凝土应用于钢桥面铺装的技术。

First, based on investigating the damages of deck pavement, an effect way to improve the durability of deck pavement, through improving the properties of pavement concrete, is proposed.

首先，通过对桥面铺装的病害进行分析，提出改善桥面铺装层混凝土的特性是提高铺装层耐久性的有效途径。

Air void is one of the key indexes in the quality control of asphalt pavements. It is more strictly restricted to use epoxy asphalt concrete on deck pavement of long-span Bridges.

空隙率是沥青路面施工质量控制中的关键技术指标之一，由于环氧沥青混凝土大多用在大跨径钢桥面铺装中，因此，对空隙率的要求更为严格。
