HMA OVERLAY CONSTRUCTION WITH ONE PASS/LANE WIDTH PCCP RUBBLIZATION

摘要: Various Portland Cement Concrete Pavement (PCCP) types were originally constructed on the Illinois Interstate System. The PCCP included Jointed Reinforced Pavements (JRCP), (JCP), and Continuously (CRCP). Major distresses are slab cracking, joint deterioration faulting, CRCP "punchouts", PCC deterioration, Hot Mix Asphalt Overlay (HMA OL) reflective cracking subsequent crack deterioration. extent severity increase considerably as pavement ages. Many of original pavements System have been rehabilitated. DOT (IDOT) used repair/rehabilitation techniques such jacking, patching, repair/replacement, diamond grinding, milling, HMA overlay in initial rehabilitation projects. complicating factors arise selecting options, particularly when section has previously This article discusses fracturing techniques, equipment developments, IDOT rubblization experiences, considerations, two dense-graded mixtures, indications for future.
