Patch repair systems

摘要

To the highway engineer patch repairs offer a fast, efficient and cost-effective way of removing defects; safety hazards; maintaining skid-resistance; preserving and protecting roads against the damaging effects of water. To obtain the best results it is necessary to give careful consideration to a wide range of detail, to plan and design the work carefully. The speed of the patching operation and the short duration of time during which motorists are inconvenienced is also an important consideration and an advantage on roads carrying high volumes of traffic during peak periods. Howard Robinson from the Road Surface Treatments Association (RSTA) examines the different types of systems that can be used.
