An improved backcalculation method to predict flexible pavement layers moduli and bonding condition between wearing course and base course.
… interface condition between the wearing and the base courses in addition to the layer moduli, which can be considered an improvement to the existing procedures. A two stage database procedure has been used to predict the above parameters and to facilitate the determination of the deflection …

High Reclaimed Asphalt Pavement in hot mix asphalt
… of RAP that can be used to 15% for surface courses and 25% for the intermediate and base courses; however, other states have implemented much higher RAP percentages. The limitations are placed because the interaction between the virgin and residual RAP binder is unknown, with respect to the …

Field observations of the early-age behavior of jointed plain concrete pavements
… highway pavements with open graded stabilized base courses have been found to develop non-uniform, transverse saw-cut joint-crack developments and extensive slab movement behaviors, which cause unwanted premature joint failures. Phase I of this study determined the variables associated with the …

Comparing Layer Types for the Use of MEPDG for FDR Design
… practice is to treat FDR as an unbound granular base layer, but this does not account for the added stability of the selected stabilization technique. However, previous research has shown that FDR may be more accurately characterized as a less-aged asphalt concrete. Until a new layer type is …

Permanent deformation behavior of unbound granular materials and rutting model development
… inadequate rut estimates in unbound aggregate base/subbase layers by discounting the contribution of stress state from the original Tseng and Lytton (1989) model. This research study was aimed at developing a new permanent deformation prediction model that would properly take into account the …
