TERMINAL TREATMENTS FOR ILLINOIS CONTINUOUSLY REINFORCED CONCRETE PAVEMENTS

As part of an extensive study conducted to determine the significant relationship between the behavior of CRC pavement and various design features, an evaluation was made of several types of anchor lug systems and terminal joints. Movement of the ends of CRC pavements can exert damaging forces against bridge structures and adjacent conventional pavement. To prevent this type of damage, some type of terminal treatment is necessary at each free end. A terminal treatment can be designed either to restrain the movement (an anchor system) or to accommodate the movement (a terminal joint system). Because the optimum number and spacing of anchor lugs for various soil conditions and subbase types were not known, the number and spacing of lugs were varied at different locations in the state and the behaviour of the various lug arrangements were compared. All combinations of lug spacing and number of lugs appear to have been effective in partially restraining the pavement movement, however, distresses in the lug area have developed at some locations. In an effort to find a less costly yet satisfactory method of alleviating the effect of end movements, ten wide-flange beam terminal joints were constructed at two locations. The data indicate that the terminal joint provides an effective method of accommodating the movements at the ends of pavements at a lower cost than restraining the movements with anchor lugs. /FHWA/
