Narrative:

We were taking off on runway 18L in clt at a heavy weight. It is well known by crews that there is a significant bump where [runway] 18L and runway 23 intersect. At the heavy weight we were at; a significant bouncing up and down of the nose occurred. Control of the aircraft was maintained throughout the takeoff roll. The effect of the bump can be reduced by adding some back-pressure on the control wheel. Crewmembers should not have to be doing this at an airport. This bump is getting worse and is similar to the way the intersection of runways 35 and 27R in phl used to be. That unacceptable condition was fixed and I strongly feel that this condition in clt also needs to be fixed.

Title: A CRJ-200 Captain reported the significant bump on CLT Runway 18L at the intersection of Runway 23 is apparently becoming more pronounced over time forcing a nose strut bouncing motion.
