Linear Viscoelastic Properties of Bituminous Binders and Mixtures at Low and Intermediate Temperatures

ABSTRACT Within the framework of a partnership between the DGCB of the ENTPE, Appia and Eurovia, a research program including a large experimental campaign on the viscoelastic behavior of different bituminous materials was developed. The aim is to establish the links between the viscoelastic properties of binders and those of bituminous mixes at low temperatures. The viscoelastic behavior of binders was evaluated using cyclic tests (frequency domain) and Bending Beam Rheometer tests (time domain). The viscoelastic behavior of bituminous mixes has been studied by performing complex modulus tests in tension/compression. Some pertinent links between bituminous binder and mix properties are established. Characteristics which are pertinent and discriminating enough with regard to the low temperature properties of bituminous mixes are presented.
