Paper Abstract

Results related to the development of an inorganic matrix that is suitable for filling narrow cracks and thin delaminations on bridge decks are presented in this paper. Almost all the repair materials currently available for these types of repairs are organic polymer based matrices. These matrices create a discontinuity in the modulus of elasticity and water permeability. These discontinuities result in the failure of repairs within about five years. The matrix used in the current investigation has a modulus of elasticity and permeability characteristics that are similar to the concrete used in the bridge decks. The primary properties investigated were: bonding to cracked surfaces, flow characteristics, ease of application, and mechanical characteristics. This paper discusses these properties, matrix performance and matrix viability for use in automated nondestructive robotic delivery system to fill delaminations and narrow/hairline crack in bridge decks.
