Many highway agencies are finding that rubblization of the deteriorated concrete and overlaying with HMA is the fastest, most cost-effective rehabilitation method. Providing pavement drainage is critical to the success of rubblized pavements. Edge drains are installed or replaced prior to fracturing the concrete. Any existing asphalt overlay or patches are removed. The concrete is fractured and rolled to achieve an interlocked, unbound base layer. The typical production rate when rubblizing is up to one lane mile per day per machine. Then the HMA overlay is applied.
