Resum
The oedometer is one of the simplest and most reliable laboratory tests. Its main drawback is that stress state is not fully known. Over the years, a number of enhancements were intended to overcome this limitation. This work presents the development of a large size oedometer for testing gravels made of crushed rock under varying moisture conditions. Load application is done by air pressure acting on the upper end of the specimen (Rowe type oedometer), and the lateral stress is measured using a ...
