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.
