Syedov A. Preventive maintenance of destructions of road asphalt pavement in aggressive environments of chloristil anti-ice materials

Object of study: asphalt covering. Motivation of way of reducing a destroying influence of aggressive ambiences of chloristil anti-ice materials on asphalt covering. Methods of study and equipment: standart methods of asphalt studing; special- determination of the wetting marginal corner ; asphalt wear capability; asphalt toughness when destroying by round-robin loads. Regularities of road asphalt covering destroying processes under the complex action of transport loads, natural factors and aggressive ambiences of chloristil anti-ice materials were elaborated; critical concentrations of aggressive preventive maintenance of asphalt covering destroying was mo- tivated; technology of struggle with winter sliding. It was advised to reduce lestructible influence аggressive ambiences of anti-ice materials by adjusting their properties by adding phosphates. Degree of introduction: introduced in Artemovsky RayDRSU Doneckoy area. Range of usage: usage on the highways and aerodromes.
