A Proposal to Characterize the Angular Speed and Acceleration of the Torsional Recovery of a Polymer-Modified Asphalt Binder Incorporating Synthetic Wax

The objective of this study is to propose a simple methodology based on the Newtonian mechanics or classic kinematic laws for the characterization of the average torsional recovery speed (?) and the torsional recovery acceleration (?) of a polymer-modified asphalt binder incorporating a type of synthetic wax as a warm mix additive. The correlation of the rheological properties of the modified binder in terms of the torsional recovery (TR), along with the engineering properties of prepared warm mixture asphalt in terms of resilient modulus (MR) and indirect tensile strength (ITS), were evaluated. The results indicated that TR, ?, and ? of the asphalt binders increase as the synthetic wax content increases. The results also indicated that TR, ?, and ? have strong correlations with rutting factor (G*/sin d), non-recoverable creep compliance (Jnr), and recovery percentage (R) of the asphalt. Moreover, there is a significant relationship between the parameters of TR, ?, and ? and the engineering properties of the mixture samples, irrespective of the construction temperatures.
