ABSTRACT
Abstract The maintenance of highway structures requires engineers to overcome very demanding constraints. Whenever possible traffic flows must be maintained, and unavoidable delays reduced to minimum. Access for repair and refurbishment can often be difficult and a high quality of work must be produced in the shortest possible time. The paper presents a number of case histories which demonstrate the role that sprayed mortar can play in achieving these objectives. Keywords: Sprayed mortar, highway structures, maintenance, refurbishment, repair
1 Introduction
The importance of achieving the full design life of highway structures through effective maintenance and refurbishment is recognised around the world. In the United Kingdom, the Highways Agency has implemented a 15 year programme for the rehabilitation of Motorway and Trunk Road bridges [1]. However, traffic volumes on the Motorway and Trunk Road network are high and continue to rise. Reducing the impact of this work presents a continual challenge to engineers.
