INTERSTATE ASPHALT DEMONSTRATION PROJECT NH 0762-038 (RUBBLIZATION)

This report documents the design and construction of the first rubblization project initiated by the Colorado Department of Transportation. The project was selected to demonstrate the resonant and multi-head breaker methods of rubblization of concrete pavement. Work consisted of rubblizing existing concrete pavement. The resonant breaker method rubblized 39,361 sq yd of concrete, while the multi-head breaker rubblized a total of 39,498 sq yd of concrete. Three 2-in. lifts of a hot bituminous pavement (HBP) were placed on the rubblized concrete. Edge drains were used to control subgrade moisture. A total of 18 moisture probes were installed to evaluate the effectiveness of edge drains. A tipping bucket rain gauge was installed to record precipitation data. This study will focus on the cost effectiveness of rubblization on jointed plain concrete pavement with alkali-silica reactivity. The French Rutting Tester and the Hamburg Wheel Tracking Device indicate the HBP will resist rutting and moisture damage. Moisture probe data indicates moisture is being removed from pavement sections. Field performance data will be conducted each year for the 5-year study period. Evaluations will consist of crack mapping, rut measurements, falling weight deflectometer measurements and observation of edge drains. Long-term performance information provided by this study will determine the overall life cycle cost of rubblization with the asphalt overlay.
