Yefremov S. Longevity asphalt concrete in the conditions of influence of aggressive environments

An object is longevity and corrosive stability of asphalt concrete in the conditions of the compatible operating on him of the mechanical loadings and liquid aggressive environments; a purpose is research of influencing of liquid aggressive environments on longevity of asphalt concrete and establishment of conformities to the law of his destruction in the conditions of compatible action of these environments and mechanical loadings; methods - analytical and numeral; novelty - intercommunication is set between the regional corners of moistening of surface of mineral materials of different origin liquid environments and ability of environments to removing a layer by the layer of bituminous tapes from these substrate, diffusion of aggressive environments is probed in a bitumen, the decline of longevity of asphalt concrete is set at the compatible action of loading and liquid environments by comparison to destruction of him in an air environment, it is shown that with the increase of coupling of bitumen with mineral materials time to destruction of асфальтобетона in liquid environments is appropriately increased, the criterion of estimation of firmness of asphalt concrete is offered; results are a express-method of determination of сoefficient of stability of asphalt concrete against the action of water, method of the automated determination of coupling of bitumen with glass and mineral materials, the coefficient of firmness of asphalt concrete is offered in aggressive environments for prognostication of his longevity; a sphere of the use is build laboratories of highway industry.
