Polymer concrete has been used for years to repair portland cement concrete. A monomer system is mixed with well-graded aggregate and placed in the repair area. After the monomer cures, a strong durable material is produced which bonds well to portland cement concrete. Special mixing and placing equipment was developed for a large pavement repair job in Houston. Longi-tudinal cracks, longitudinal lane-shoulder joint separations, spalls, punch-outs, and other types of damage were repaired.
