Title: Fatigue Characteristics and Damage Model Development of Bitumen-Stone Adhesive Zone
Accession Number: 01124388
Record Type: Component
Availability: Transportation Research Board Business Office 500 Fifth Street, NW Abstract: In asphalt mixtures mortar acts to bond stone particles. Between the mortar and stone a very thin adhesive zone exists that is subjected to fatigue. Adhesive failure may contribute to the development of ravelling, which is the major defect of noise reducing porous asphalt wearing courses applied on the Dutch primary road network. In this study, the fatigue properties of adhesive zones are determined by tests on stone columns bonded by a very thin layer of bitumen. Dynamic mechanical analyzers (DMA) and dynamic shear rheometers (DSR) are used to perform uniaxail tension and shear fatigue tests on adhesive zones at temperatures ranging from -10C to 20C. With the aid of experimental data, a damage model for adhesive zone was developed taking into account 2D states of stress and random stress history. Model verification showed that this model was capable to capture the damage development in the adhesive zone.
