Selecting Rubblization for Rehabilitation of Concrete Pavements: Case Studies in Texas

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 the concrete in place and leave pieces small enough that reflective cracking problems are significantly reduced or ideally eliminated. This paper presents overviews of three topics relevant to rubblization. First, an overview of slab fracturing techniques, including rubblization, for concrete pavement rehabilitation is given. While construction specifications for rubblization exist within many agencies, detailed site investigation plans to evaluate whether a project can be rubblized are generally lacking. Therefore, a comprehensive plan for evaluating the suitability of a project for rubblization is presented next. This plan involves project history, visual site inspection, and ground-penetrating radar, falling weight deflectometer, and dynamic cone penetrometer surveys. Finally, case studies of pavements in Texas illustrate the application of the investigative methods described.
