This course will introduce you to materials, criteria, and procedures for rapid repair of uncontrolled cracks and spalls in rigid pavements by using epoxy resin grouts, mortars, and concretes. Seven crack conditions that encompass most of the crack types that will be encountered will be discussed. This course is applicable to the repair of rigid pavements on roads and airport runways and taxiways Course Outline 1. PURPOSE 2. DEFINITIONS 3. GENERAL PROVISIONS 4. APPROVED EPOXY MATERIALS 5.
