CRACK REPAIRS TO CONCRETE PAVEMENT

Repair techniques used on Interstate Loop 610 in Houston and on U.S. 59 in District 11 about 100 miles north of Houston are described in this article. A procedure for repairing extensive longitudinal cracking on I-610 was developed with the assistance of the Center for Transportation Research at the University of Texas at Austin. Polymer concrete consisting of aggregate with a polymer binder was used to repair the portland cement concrete. Details of the monomer system are described. Over 100,000 linear feet of cracks on I-610 were repaired by enlarging them and filling them with PC in the West Loop. A 1985 evaluation of the crack repaired on the South Loop two years earlier, indicated that 80 to 90 % were in good condition. A repair project on U.S. 59 is described which served as a pilot study to determine the effectiveness of various types of concrete repairs that might be used in flexible-over-rigid sections. Replacement using precast drop-in units is also described.
