Highway Uses of Epoxy with Concrete
[ NCHRP 20-05 (Synthesis of Information Related to Highway Practices) ]

  Project Data

Many agencies have used epoxies since 1954 for various purposes such as bonding concrete, filling cracks, anchoring bolts, etc. The results of this use has varied depending primarily on its application. Reasons for its success or failure are noted. An epoxy is made by mixing a resin with a curing agent. Many different resins, curing agents, and modifiers are available. The type and amount of curing agent modifier used affects the properties of the aired epoxy system. Among the properties that are affected are viscosity, cure rate, shrinkage, flexibility, plasticity, thermal expansion, strength, and appearance. Specifications and tests for epoxies have been developed by AASHTO, ASTM and ACI. This publication reviews highway uses of eposy, and discusses in detail, the material itself--it's handling, it's properties, tests and specifications. A conclusion, references, and bibliography are also included.  The report for this topic can be purchased at http://www.trb.org/news/blurb_detail.asp?id=3448
