• Abstract:
  Preservation treatments help in extending the remaining service lives of pavements, but at the same time, they ; may have substantial environmental impacts due to the acquisition of raw materials, transportation of the extracted ; materials, manufacturing of the final product, and the use of various equipment during the treatment process. ; Traditional and accelerated maintenance, repair and rehabilitation (MRR) techniques were identified for both ; flexible and rigid pavements. Environmental impacts of the commonly used MRR strategies were calculated. A ; life cycle assessment (LCA) approach was used, taking into account the life extension of the pavement for each ; type of strategy. The scope boundary included only the construction activities relevant to pavement MRR. LCA ; results showed that for flexible pavements, accelerated rehabilitation techniques like partial or full depth ; reclamation have less life cycle environmental impacts than traditional techniques like milling and overlay or total ; reconstruction. For rigid pavements, all the rehabilitation techniques are comparatively new. The environmental ; impacts were found to be similar for both traditional techniques like concrete full depth repair and accelerated ; techniques like precast concrete pavement systems. Minor treatment processes for both flexible and rigid ; pavements like fog seal, crack seal, concrete seal joints, diamond grinding, and concrete partial depth repair have ; minimum impacts with maximum benefits when the corresponding life extensions are compared. The results ; obtained can assist highway construction management professionals to select environmentally sustainable MRR ; solutions.
