Influence of Temperature on the Formation of Damages in Asphalt Concrete Pavements under Climatic Conditions of the Republic of Belarus

DOI: 10.3846/bjrbe.2012.06
 
Climatic conditions of the territory where the road is located (air temperature, solar radiation) influence the “work” of asphalt concrete pavements. The influence causes shear deformations at high positive temperatures and the occurrence of cracks at low negative temperatures. In the late 80s, in the USA the asphalt pavement design system Superpave (Superior Performing Asphalt Pavements) defined the temperature limits of pavement “work”. The Performance Grade parameter has been introduced associated with the choice of bitumen. Based on the long-term climatic data the temperature limits have been determined for the territory of the Republic of Belarus.
 
Keywords: climatic conditions, asphalt concrete pavements, ruts, temperature cracks, reflected cracks, weather-climatic factors, Superpave, Performance Grade (PG), zoning.
