Physical-Mechanical Properties of Cement Stabilized RAP/Crushed Stone Aggregate Mixtures
Abstract
The paper presents and analyzes the results of testing the properties of cement stabilized mixtures of reclaimed asphalt pavement (RAP) and crushed stone aggregate (CSA). Tests were carried out on reclaimed asphalt pavement and crushed stone aggregate mixtures with varying RAP content (0%, 20%, 40%, 60% and 80%), as well as with a varying addition of cement (3%, 5% and 7%). The purpose of these tests was to determine the optimal proportion of recycled asphalt pavement in a mixture with crushed stone aggregate, and the optimal addition of cement as a hydraulic binder. Furthermore, the aim was to determine physical-mechanical parameters: the indirect tensile strength (R-t) and the dynamic modulus of elasticity (E), which are applied in pavement design during the process of cold recycling. On the basis of the obtained values, categorization of the stabilized mixture was carried out according to the standard EN 14227-10: 2006, which continues to be applied in the design of pavements. The m...aximum proportion of recycled asphalt in the stabilized mixture was determined as being up to 60%; the stabilized mixture was categorized into the "T1" and "T2" categories - gravelly soils.
