Viscoelastic characterisation of warm asphalt mixtures
The characterisation of the visco-elasto-plastic properties of asphalt materials are important for a better understanding of the pavements’ mechanical behaviour and performance. The complex modulus aims to characterise the linear viscoelastic properties of the material present in the domain of small deformations. This article aimed to characterise the viscoelastic properties of hot and warm asphalt mixtures, by adding surfactant additive to the latest. Four asphalt concrete mixes with basalt aggregate and the following binders: conventional 50/70 penetration, polymer-modified SBS 60/85, rubber asphalt (AB 8) and modified asphalt with Trinidad Lake Asphalt (CAP TLA) were designed for this study. In addition, the parameters of adhesiveness and resistance to hot and warm mixtures were obtained. Through the study it was observed that mixtures with conventional binder presented similar behaviour both in conventional hot and warm mixes. Modified binder mixes show important variations both in viscous and elastic phases, comparing hot and warm production methods, with greater differences found in the polymer-modified mixtures.
