Description
This study was undertaken to find economical methods to reduce reflectance cracking of bituminous overlays placed on Portland Cement Concrete. The four methods studied were pavement cracking, open graded bituminous base course, aggregate interlayer, and increased thickness of the bituminous overlay.
Pavement cracking was found to be an effective and economical method of reducing reflectance cracking. The aggregate interlayer and added bituminous thickness were found to reduce reflectance cracking to some degree but the added cost may exceed this benefit. The open graded bituminous base course was not an effective method of reducing reflective cracking on this project.
