The Impact Factor measures the average number of citations received in a particular year by papers published in the journal during the two preceding years. 2017 Journal Citation Reports (Clarivate Analytics, 2018) IF: 1.4 To calculate the five year Impact Factor, citations are counted in 2017 to the previous five years and divided by the source items published in the previous five years. 2017 Journal Citation Reports (Clarivate Analytics, 2018) 5-Year IF: 1.3 The Immediacy Index is the average number of times an article is cited in the year it is published. The journal Immediacy Index indicates how quickly articles in a journal are cited. Immediacy Index: 2.2 The Eigenfactor score, developed by Jevin West and Carl Bergstrom at the University of Washington, is a rating of the total importance of a scientific journal. Journals are rated according to the number of incoming citations, with citations from highly ranked journals weighted to make a larger contribution to the eigenfactor than those from poorly ranked journals. Eigenfactor: 0.00034 The Journal Citation Indicator (JCI) is a single measurement of the field-normalized citation impact of journals in the Web of Science Core Collection across disciplines. The key words here are that the metric is normalized and cross-disciplinary. JCI: 0.46 SJR: 0.333 SNIP: 0.606 CiteScore™:: 3.1 H-Index: 31

ABSTRACT

Creep/relaxation of asphalt consisting of the thermorheological binder material (bitumen), inclusions (aggregates), and air voids may lead to considerable permanent deformations (rutting). Although viscoelastic models are suitable to describe the asphalt behavior at low stress levels and in the low-temperature regime, material models taking plastic deformation into account are needed in order to capture the thermorheological behavior of asphalt at elevated temperature regimes. In this paper, the deformation behavior of asphalt is described by means of a creep/relaxation function, which, in a second step, is extended toward viscoplastic deformation. The underlying model parameters describing the thermorheological nature of asphalt are determined from a multiscale model considering five observation scales. The model, implemented into a Finite Element program, is used for determination of permanent deformations, as illustrated by the reanalysis of triaxial cyclic compression tests and the prediction of rutting in flexible pavements.
