URETEK injected polyurethane into the foundation soils of the pavement system using a specialized application of the URETEK Deep Injection® (UDI) process known as Joint Vicinity Injection (JVI). URETEK performed JVI on six successive transverse joints in an eastbound travel lane segment of the I-90 test site. PennDOT performed post-injection FWD testing 24 hours after JVI completion to assess void reduction and improvement in LTEs of the joints.
