Rubblization for Rehabilitation of Concrete Pavement in Texas: Preliminary Guidelines and Case Studies

Rubblization is a unique means of rehabilitating concrete pavements by in-place conversion of the old concrete pavement into a useable base. Rubblization employs machinery that will break apart the concrete in place and leave pieces small enough that reflective cracking problems are significantly reduced or ideally eliminated. This report presents an overview of recommendations from other states that routinely use rubblization, and then focuses on preliminary guidelines and case studies for conducting rubblization in Texas. First, a plan for determining the suitability of a project for rubblization is presented. Next, two case studies illustrate how to evaluate a project to determine whether rubblization is a viable rehabilitation option. Finally, draft construction specifications for conducting rubblization in Texas are presented.
