Evolving Rehabilitation Strategies for Asphalt Pavement

Strategies for rehabilitation of flexible pavements have traditionally included mill and overlay or reconstruction. Three new strategies for flexible pavement rehabilitation currently being utilised by the Nebraska Department of Roads include partial depth in-place recycling, full depth in-place recycling and full-depth reclamation. Cost differences between the new and the traditional strategies were evaluated and conditions under which the new strategies are appropriate for use are discussed in this paper. A comparison based upon cost of rehabilitating a section of pavement using the two conventional and three new strategies found that the three recycling strategies provide flexible pavement which costs more than mill and overlay but less than complete reconstruction.
