Raised repair/infill

It is on the A38 eastbound shortly after you have driven past the Lower Dean slip road for Dean Prior Buckfastleigh B3380 and are continuing on the A38 eastbound. In the left lane only there is a ridge equivalent to a speed bump right across the left lane that is terrible to drive over – you cannot safely slow down enough to take it gently and my car goes over it with heck of a bang and jolt each time unless I can pull out in time to avoid it. I am worried it will damage mine and other vehicles. It is quite clearly raised a significant amount above the road surface. I don’t know if the material has expanded after a repair or it was always like that. It has been there for awhile but I am forcibly reminded every time I hit it!

Please could it be sorted before it causes an accident or damage – hitting it in icy conditions could be lethal.
