Abstract:The overall value of using thin surfacing maintenance treatments to extend and preserve the
performance of existing pavements has been widely recognized. This study has focused on
evaluating the cost effectiveness of commonly used individual treatments. In addition, an effort
was made to identify additional beneficial treatments for consideration by PennDOT.
This work consisted of three tasks, conducting a literature review, carrying out a survey of other
states, and performing cost benefit analysis of maintenance treatments. Each task produced
specific results. The literature review searched for information about the successful use of thin
surface maintenance treatments and documentation of cost effectiveness. In addition to
identifying commonly used treatments several less common treatments were researched as well.
E-krete was identified as an additional thin surface treatment which has the potential to be
beneficial. It has been approved by PennDOT for evaluation. Some questions about the effect of
this material on asphalt pavement recycling were not answered in the literature.
