Modifying Additives Effect on Use Properties of Asphalt Concrete

Abstract:

The article dwells on the results of the survey of the asphalt concrete modified with various additives. It contains the results of the impact made by the modifying additives on the physical mechanic and performance properties (rutting resistance, fatigue life and permanent deformation accumulation resistance) of the Type A Grade I asphalt concretes. In the article the regularities of the influence exerted by the formula-related and technological factors on the asphalt concrete properties were established. Consistent with the obtained results forecasting of rutting in accordance with AVTODOR STO 2.28-2016 and forecasting of fatigue damage accumulation on the basis of the Miner’s cumulative model of damage linear addition were executed. On the basis of the forecast results the interrepair life of the road structures with the pavement courses of asphalt concretes containing the surveyed modifiers was evaluated.
