When it comes to road repairs, particularly on arterial routes, efficiency is everything. Apart from the risk of damage caused to road-users by poorly maintained paving, there’s usually a high cost in shutting down roads for repairs and a very small window when the road can be worked on.
Usually, problems arise at seams in the road, such as manhole covers or expansion joints, where two materials meet and react differently under heavy loads. This last ‘couple of percent’ of the total job often costs the developers days if not weeks and can be the first elements to fail in the future.
