Effects of Heavy Weight Jackhammer
The objective of this study is to determine the extent of damage, if any, of using a heavyweight jackhammer, 65 lbs., as opposed to a lighter weight jackhammer, 35 lbs., for removing deteriorated concrete during bridge deck repair. The use of a heavier weight jackhammer allows more efficient and timely repair operations. However, there are questions of potential damage to the bridge deck when using a heavyweight jackhammer. In conjunction with the above findings it was determined that allowing the use of 65 lb. jackhammers for contracted maintenance repair projects (on un-programmed bridges) is not in conflict with Missouri Department of Transportation's special provisions limiting operations to a maximum 35 lb. jackhammer on bridge rehabilitation construction contracts.
