Resin Concrete from Bomb Damage Repair of Airfield Pavements.

摘要

This study was Phase I of a two phase study and was conducted to determine whether commercial liquid resins can be used successfully as binders or matrix materials with aggregates fo form a resin concrete for rapid repairing small damaged areas in airfield runway pavements. One type of liquid resin system, a highly reactive polyester, was shown to have the necessary properties. It came nearest to meeting all of the design objectives, including aggregate penetration, polymerization rate, early strength development, ease of application, and cost. To meet all of the design objectives, further studies of the identified material should focus on (1) material improvement in the areas identified as having performance weaknesses (e.g., bonding to wet aggregates), (2) repair patch designs which relate to composite material properties to patch size and subgrade support quality, and (3) application equipment criteria and design. However, the sponsoring agency recommends that new concepts be investigated rather than continue with further work on this particular resin system. (Author)
