Epoxy and Resin Based Adhesive Bonding Systems (ERB)

Epoxy and resin based adhesives are chemical products utilized in highway construction for a host of different applications. Some of these applications include affixing raised pavement markers and traffic delineators to roadways, as well as dowel connectors in concrete pavement joints and sealing segments of post-tensioned precast concrete structures. These products can be single component or multiple component systems and are available in a wide variety of chemistries. This program is not intended and should not be used to qualify products for use in sustained load (creep) applications. The intent of this program is to assist state highway agencies with prequalifying epoxy and resin based adhesive bonding systems for use in applications where sustained loads do not exist.

The ERB technical committee is responsible for implementing and maintaining a NTPEP Project Work Plan that accomplishes this initiative The ERB technical Committee convenes annually at the NTPEP National Meeting. During this meeting, modifications to the work plan are discussed and then balloted for implementation.​

NTPEP tests products according to a Project Work Plan, which describes the laboratory and/or field test protocols used to conduct the evaluation. The Project Work Plan is a consensus-based document and includes peer review and input from industry experts. Each Project Work Plan is adopted after receiving at least two-thirds affirmative support from 52 AASHTO member states. The Project Work Plan is the basis for host states to conduct their testing and evaluation. When implemented by state DOTs, their own state standard specifications may supersede the NTPEP Project Work Plan. Industry is advised to be aware of state-level requirements, which may supersede basic NTPEP testing.
