Very dangerous road repairs

Sections of the M25 between the dartford crossing and the A12 exit In both directions have been repaired in a very dangerous way which almost took my life today. There are long thin repairs which run parallel with the road that have been done very dangerously. It looks like the surface is some sort of Bitchemen and looks very shiny. This surface is very slippery and when wet is like ice. I ride a motorcycle and today it was raining and when I hit one of these surfaces I lost complete control and sent me into a death wobble at 70mph and I’m surprised I managed to gain control. This is going to kill a motorcyclist sooner or later and Urgently needs to be addressed before it’s too late.
