Abstract
Rubblization is a unique means of rehabilitating concrete pavements by in-place conversion of the old concrete pavement into a usable base. Two primary methods of rubblizing exist. One method uses a multiple-head breaker (MHB), which breaks the entire lane width in one pass. The other method uses a resonant breaker (RMI), which performs multiple passes across the lane width to rubblize the pavement. Texas has many miles of old jointed concrete pavements needed rehabilitation; thus, this project evaluated field projects and the rubblization process to develop guidelines for performing rubblization on Texas Department of Transportation (TxDOT) projects.
