Laboratory Evaluation of Constructibility Issues with Surface Treatment Binder (open access)

Laboratory Evaluation of Constructibility Issues with Surface Treatment Binder

This report discusses a study related to the use of emulsified asphalt (EA) as a binder for sealing roads after construction. Due to the number complex variables that affect EAs, this research is meant to help TxDOT personnel better predict which EA will be most effective and bond most quickly to allow roads to open for traffic.
