高性能混凝土在路面工程中的应用

Application of High Performance Concrete in the Road Surface Engineering

高性能混凝土是一种新型的高技术混凝土,已经被重要结构工程广泛采用,并在高层建筑、大跨径桥梁等工程中显示出其独特的优越性。"双掺技术"的提出使得普通混凝土路面的路用性能有了明显改善,表现为强度提高、脆性下降,抗冻性和耐磨性均有增强,故这是值得推广的一项新技术。

The high performance concrete is one kind of new high technique concretes, it has already been widely adopted in the important structure engineering, and display its special superiority in the mul- tistoried buildings and large-span bridges. Double-penetration technique greatly improve the highway functions of common concrete pavement, including strength increase, brittleness decrease and the increase of capacities of anti-freezing and wearproof. Therefore, double-penetration technique is worth of wide application.
