A Guide to Concrete and Soil Compaction techniques. Paperback book published by Wacker (no date).
Some of you may have realized that I like the unusual find. A book that is so specialized that it’s hard to imagine anyone being interested in it… that is, hard to imagine unless you're me. I have an idea that there are people out there interested in Wackers. I can even imagine someone with a wacker collection desperately searching for anything else wacker related (… like this book). Wacker swap meets are probably not that common, but I reckon there would be a wacker forum somewhere on the interwebs.
Here are a few fine examples of the wacker as shown in this book:
Marginal compaction by means of a long-stroke rapid impact tamper.
Repair work on bituminous material with rapid impact tamper. (Notice the hat.)
Rotary vibrator laying pavement slabs
Diesel vibrating compactor compacting bituminous material
Electric long-stroke vibratory tamper
