Rubblization and Crack and Seat as Major Rehabilitation for Concrete Pavements

Project Description

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 breaks apart the concrete in place and leaves pieces small enough that reflective cracking problems are significantly reduced or ideally eliminated. Researchers developed guidelines on how to conduct site investigations to determine if rubblization plus an overlay is an appropriate treatment for individual sections of distressed concrete pavement. For those projects identified as good candidates, decision criteria will help select which fracturing technique is optimal. For each fracturing technique, this project provided the Texas Department of Transportation (TxDOT) with construction specifications, overlay mix selection criteria, and structural design recommendations. The recommendations were applied to two actual TxDOT highway rehabilitation projects.
