The sub-grade layer of a pavement is, essentially, the underlying ground. It is also known as the "Formation Level", which can be defined as the level at which excavation ceases and construction starts. This page aims to explain all....
The construction method comprises the following steps of: filling an earth-filled road foundation by layers, compacting by layers to finish all the constructions, carrying out quality test to be qualified, and continuously carrying out paving construction on a pavement underlayer; after all the ...

In this paper, a comparison between pavement responses is performed by considering two different models for the linear viscoelastic behavior of an asphalt concrete layer. Two models, the Maxwell model and the Kelvin-Voigt model, are generalized. The former is used in ABAQUS and the latter in KEN...

PARAMETER ESTIMATES OF PAVEMENT STRUCTURE LAYERS AND UNIQUENESS OF THE SOLUTION The question of uniqueness of backcalculated moduli of a pavement structure subjected to axisymmetric loading is addressed. Two simple examples are present... D Stolle,D Hein - International Symposium on Nondestructive Testing...
The low velocity layers of pavement systems usually lead to serious subsidence and deformation of a roadbed.The OCCAM algorithm has been successfully used to invert transient Rayleigh wave dispersion curves for lower velocity layers.The new efficient algorithm can improve shear wave accuracy and resolut...
The beauty of a good base layer is in its versatility — we often use the same sets for skiing, winter camping, and early-morning fishing. Because of this, we aimed to use them as part of our layering systems in a variety of activities, and we’ve gone pretty far flung doing so. ...
In the PMT facility, the model pavement structure was constructed in a 1.0 × 1.1 × 0.6-m steel tank, and the wheel loading from the vehicle was simulated using a circular steel plate subjected to sinusoidal-type axial loading through an actuator assembly. The results of this study indicate...
