• Description:
  The Alaska DOT&PF wants to construct and maintain asphalt concrete (AC) paved highways in a way that minimizes roadway lifecycle costs while preserving acceptable
  
  performance. Thermal cracking is a natural feature of most paved Alaska roadways that influences both long term maintenance costs and the driving public’s perception
  
  of road performance. This work plan for a research test section provides construction and maintenance procedures to address what is arguably the most severe form of
  
  thermal cracking — major transverse thermal cracks.
  
  A newly constructed AC pavement surface will be modified with the addition of presawn transverse cracks (placed according to specified spacing and cut depths). Based
  
  on previous experience it is expected that many of the presawn cracks will become active transverse thermal cracks. Alaska experience suggests that this controlled form
  
  of thermal cracking result in a “better thermal crack” in terms of ride roughness and visual appearance. Alaska experience further suggests that such cracks should require
  
  little if any sealing maintenance over the life of the pavement. The work plan includes long term monitoring and maintenance methods that will be used to evaluate the
  
  performance of the experimental sections.
