Frost Susceptibility of Unbound Bases
The Mineral Criterion is an important part of the evaluation process of frost susceptibility concerning base materials for road construction in Austria. Dependent on grain size distribution, it defines mineralogical limiting values for the fraction < 0,02 mm. On the one hand the Mineral Criterion has proved successful, but on the other hand it turned out to be too strict. In order to improve this criterion, 15 different base materials have been examined. The results of reliable mineralogical analyses have been correlated with frost heave tests and moderate mineralogical influences could be verified. Finally, a procedure to improve the existing limiting values of the current MineralCriterion and an alternative way to assess frost susceptibility mineralogically have been introduced.
