The wear phenomenon plays a fundamental role in excavation work, as it directly affects
times and costs. While prediction models are available in the literature for rock applications,
a standardized procedure for predicting wear is not yet available for soils. In this
work, the Soil Abrasion Test Apparatus (SATA) is used to study the wear dependence from
the moisture content. 6 different types of soils were tested by varying the moisture content
and results were obtained in terms of weight loss...
The Cerchar Abrasivity test is used for assessing the abrasion of rock due to its simplicity and fast execution and it is considered one of the main wear indexes in tunnelling. Despite in standard condition the test is performed on a dry surface of a rock sample, this study introduces the possibility to carry out the test on a conditioned surface. In details, this work compares the Cerchar Abrasivity...
