Asphalt jungle

During my working life as a project manager before retirement I frequently used hot rolled asphalt with positive texture provided by coated chippings rolled in, which gave long life but was noisy.

Three years ago the nontrunk urban A road outside my house was resurfaced using a modern thin surfacing with negative texture which was certainly quieter. Now the surfacing is peeling off at many scattered locations and the areas adjacent to all the ironwork is cracking.

While I see apparent good performance by thin surfacing used on trunk roads and motorways where the base is not riddled with utility trenches and ironwork, I wonder whether it is appropriate to use thin surfacing in the urban environment? Are the above failures just a one-off or do others have similar experience at their sites?
