Rehab of D-Mix Test Track

The Texas A&M University System is seeking a qualified contractor to rehabilitate the D‑Mix test track at the RELLIS Campus. The work consists of milling existing hot‑mix asphalt, repairing the underlying flexible base, and placing a 2‑inch dense‑graded D‑mix inlay. The contractor must provide a certificate of insurance, three references, and comply with Executive Order GA‑48 and HB 127 certifications. Work must be completed within a tight construction window and meet post‑construction IRI performance criteria. • Mill and remove existing HMA to the flexible‑base level over two specified segments (≈ 7,050 ft total). • Install a 2‑inch TxDOT‑approved dense‑graded D‑mix inlay, with tack‑coat application and final cleanup. • Deliver the project by 31 August 2026, with testing and acceptance overseen by the Texas Transportation Institute (TTI).
