Resumen

Unbound granular materials used in pavement structures are subjected
to a complex stress path that includes rotational stresses. Hollow cylinder
apparatuses (HCAs) are suitable laboratory devices for reproducing stress paths
found in the field. However, as the size of the HCA depends on the size of the
granular particles, their use for testing unbound granular materials for pavements
has received limited attention in the literature. This paper presents some results
about the behavior of granular materials for pavements tested in a hollow cylinder
apparatus. This large HCA has hydraulic actuators for vertical movement and
torsion while shear and vertical stresses are servo-controlled to reproduce stress
paths produced by a heavy vehicle moving on a pavement structure. Confining
stress is applied using rings with controllable stiffness. The results show the effect
of stress rotation on the behavior of unbound granular materials used in pavement
structures.
