Compaction characteristic of the surface layer asphalt mixture (13-type gradation mixture) was studied using Superpave gyratory compactor (SGC) simulative compaction tests. Based on analysis of densification curve of gyratory compaction, influence rules of the contents of mineral aggregates of all sizes and asphalt on compaction characteristic of asphalt mixtures were obtained. SGC Tests show t...

Polyurethane (PU) mixture is a new pavement material with excellent performance, and most research was focused on the enhancement of but rarely dynamic property. This paper studied factors including gradation, aggregate type, PU content, which may influence property mixture. Test results showed that kind linear viscoelastic material, its modulus phase angle changed test temperature loading freq...

According to the former researcher’s presented relations for flow through rock-fill porous media, the effects of physical characteristics was not studied separately. Hence, due to the application of these relations, physical characteristics of porous materials effect must be investigated separately. In various constructed physical models of porous media, the effect of several variables such as ...

Affine Toda equations based on simple Lie algebras arise by imposing zero curvature condition on a Lax connection which belongs to the corresponding loop Lie algebra in the principal gradation. In the particular case of A (1) n Toda models, we exploit the symmetry of the underlying linear problem to calculate the dressing group element which generates arbitrary N -soliton solution from the vacu...

We construct soliton solutions for non-abelian loop Toda equations associated with general linear groups. Here we consider the untwisted case only and use the rational dressing method based upon appropriate block-matrix representation suggested by the initial Z-gradation.
