Evaluation of permanent deformation models for unbound granular materials using accelerated pavement tests

A model for predicting permanent deformation of unbound granular materials

“…Thus, the model needs to be validated using in situ pavement data, for instance, using data from accelerated pavement tests such as heavy vehicle simulators (Ahmed & Erlingsson, 2013;Saevarsdottir & Erlingsson, 2013a, 2013b. Further work should also be carried out to implement this model for real pavement conditions.…”

A Computational Methodology for Assessing the Time‐Dependent Structural Performance of Electric Road Infrastructures

“…In general, the rutting deformation is known to augment with increasing temperature and tire pressure and to be inversely proportional with respect to the subgrade strength. Studies that highlight the importance of the rutting phenomenon in the road pavement are reported in Ahmed and Erlingsson (), Darabi et al. (), Qiao et al.…”

“…In general, the rutting deformation is known to augment with increasing temperature and tire pressure and to be inversely proportional with respect to the subgrade strength. Studies that highlight the importance of the rutting phenomenon in the road pavement are reported in Ahmed and Erlingsson (2013), Darabi et al (2012), Qiao et al (2015), Rahman and Erlingsson (2015), Saevarsdottir and Erlingsson (2015). In some e-road solutions, the insertion of charging devices could lead to stress concentration in the proximity of the devices, resulting in an accelerated, deeper rutting.…”

Instrumentation and performance modelling of heavy vehicle simulator tests

“…The lateral wander of the traffic is further accounted for by taking the calculated principal stresses representing the field conditions in the middle point of each layer over the area the wheels travel over. Lytton et al (1993), Hu et al (2011) and Ahmed and Erlingsson (2013) state that a time-hardening procedure appears to provide a reasonable approach when considering the effects of various stress magnitudes on the development of rutting. This approach was used here (Saevarsdottir and Erlingsson 2013).…”
