The secret life of potholes

摘要

The general thrust of opinion Tin the press is that we are not getting on top of the pothole problem in our highways system, which seems surprising when we have the technology now to harvest energy from our roads. So why can't we repair potholes effectively and progressively reduce the backlog? It is clear from the literature over the past few decades that there is a range of technologies available for pothole repair, some involving heat, some specialist machines which will clean the hole and place in new material, some as simple as a breaker, a shovel and a compactor.
