EXPERIENCE IN TEXAS WITH TERMINAL ANCHORAGE OF CONCRETE PAVEMENT

THE EXCESSIVE MOVEMENT OF TERMINALS (OR ENDS) OF CONCRETE PAVEMENTS HAS LONG BEEN A SOURCE OF TROUBLE TO THE HIGHWAY ENGINEER. RECENTLY A NEW CONCEPT IN THE HANDLING OF TERMINAL MOVEMENT OF CONCRETE PAVEMENTS ADJACENT TO STRUCTURES HAS BEEN INTRODUCED EMPLOYING TERMINAL ANCHORAGES. A SYSTEM OF SHALLOW, INEXPENSIVE, REINFORCED CONCRETE ANCHOR LUGS, 2 FT WIDE AND 3 FT DEEP, IS CAST MONOLITHICALLY WITH THE CONCRETE PAVEMENT NEAR THE TERMINALS, ACTING TO RESTRAIN A MAJOR PORTION OF TERMINAL PAVEMENT MOVEMENT BY DEVELOPING THE RESISTANCE OF THE SOIL. IN MARCH 1959 A TWO-LUG ANCHORAGE SYSTEM WAS PLACED AT THE TERMINALS OF A JOINTED, UNREINFORCED CONCRETE PAVEMENT. SINCE THAT TIME A NUMBER OF PROJECTS HAVE BEEN BUILT EMPLOYING LUG ANCHORAGES, INCLUDING FOUR- AND FIVE-LUG ANCHORAGE SYSTEMS ON CONTINUOUSLY REINFORCED CONCRETE PAVEMENT. EXPERIENCE TO DATE WITH THESE TERMINAL ANCHORAGE SYSTEMS IS REPORTED, TOGETHER WITH THEIR DESIGN BASIS. AT PRESENT THE LUG ANCHORAGE SYSTEMS ARE PERFORMING WELL IN RESTRAINING TERMINAL MOVEMENT AND A MORE WIDESPREAD USE OF THIS DESIGN CONCEPT IS PREDICTED. /AUTHOR/
