One of the major problems with landfills is that they contain a large amount of solid wastes. Waste plastics and glasses contribute greatly to this problem, and these materials need to be managed ...

The deflection basin obtained through backcalculation analysis is compared with the measured deflection basin to determine the moduli of each pavement layer. Most computer programs use multi-layered elastic theory (MET) ...

This study was conducted to develop two types of artificial neural network (ANN) model to predict the rheological properties of bitumen-filler mastic in terms of the complex modulus and phase angle. Two ...

This study examines the effect of mixing varying percentages of nano-silica (NS), i.e. 2, 4 and 6% (by weight of polymer-modified bitumen, PMB) with PMB, in unaged and aged conditions. The Fourier transform infrared ...

Reliable assessment of in situ pavements stiffness is an important aspect in effectively managing a pavement system. The aim of this paper is to propose the new procedure, namely the wavelet-spectrogram of surface wave ...

Accurate, quick, and nondestructive in situ tests for measuring pavement stiffness, or elastic modulus, are an increasingly important element in pavement management systems. This is due to the increasing number of aged ...
