Mirage on City Pavements

Mirage Cosmology

A brane universe moving in a curved higher dimensional bulk space is considered. The motion induces a cosmological evolution on the universe brane that is indistinguishable from a similar one induced by matter density on the brane. The phenomenological implications of such an idea are discussed. Various mirage energy densities are found, corresponding to dilute matter driving the cosmological e...

On the fracture of highway pavements

A B S T R A C T Using a model of a single layered foundation to describe a highway or an airfield pavement and an integral formulation, the problem of a pavement containing on-the-top layer a crack of finite length 2c is solved for the stress distribution around the crack tip. The analysis shows that the stresses possess the usual 1/e 1⁄2 singular behavior which is characteristic of crack probl...

Behavior of Flexible Pavements on Expansive Soils

This investigation discusses the findings on analysis results of a pavement structure constructed on a relatively expansive material consisting mainly of brown clayey silt in Tebessa, Algeria. Cores were brought to the laboratory from a piece of roadwork. Remolded samples were taken from subgrade of a deteriorated road. The soils were generally found to be of medium plasticity and of a medium t...
