There are many techniques which can be used that should reduce the congestion caused by street and road works, some having a greater influence than others. However, each technique is appropriate for different situations. A series of such ideas, covering organisational issues (co-ordination, extended working hours, permits and lane rental, traffic easing and public information), surveys (survey methods and locating tags), minimising excavation (no dig technologies, keyhole maintenance, vacuum extraction, “Core & Vac” and micro-trenching), alternative materials (hydraulically bound materials, high-strength resin foam, natural cement with lightweight aggregate, warm and semi-warm asphalt and manhole repairs) and common utility ducts have been reviewed and are offered for consideration by those planning road or street works.
