Acoustic Impact Response Testing for Concrete ID: 2014-027

An innovative, non-destructive method for detecting and mapping hidden defects in concrete structures using acoustic responses excited by paintballs and airsoft pellets.

Technology Overview

This technology introduces a novel approach to assessing the structural integrity of reinforced concrete, particularly in bridge decks, by utilizing paintballs and airsoft pellets to generate acoustic signals. These signals are analyzed to identify delaminations and other defects that are not visible to the naked eye. The method stands out for its non-destructive nature and potential for automation, offering a more efficient, accurate, and cost-effective solution for infrastructure maintenance.

Key Advantages

• Non-destructive testing preserves the integrity of the structure
• Enables detection of internal defects not visible externally
• Automation potential significantly reduces manual inspection time and effort
• Provides detailed digital maps of structural defects for better maintenance planning
• Utilizes inexpensive, off-the-shelf materials (paintballs and airsoft pellets)

Problems Addressed

• Difficulties in detecting subsurface defects in concrete structures
• Inefficiencies and inaccuracies in manual inspection methods
• High costs and complexities of current non-destructive testing methods

Market Applications

• Regular maintenance and safety assessments of bridge decks and other concrete infrastructures
• Inspection services for civil engineering firms and government transportation departments
• Integration into automated maintenance systems for large-scale infrastructure projects
