What HP2 Engineering and Testing does

HP2 Engineering and Testing is a San Marcos, Texas-based construction materials engineering and testing laboratory focused exclusively on the asphalt and flexible pavement industry. The firm offers an integrated suite of services across six lines: mix design (asphalt, balanced mix design, subgrade and base stabilization, full-depth recycling), construction materials testing for subgrade, base, aggregate, asphalt, and concrete, asphalt binder testing including PG grading on virgin and recovered binders, pavement forensics with expert witness testimony, product and specification development, and education and training delivered at the HP2 facility or client sites. The underlying technology centers on state-of-the-art physical testing equipment for binder recovery, performance grading, and mix optimization, including specialized capabilities for recycled-binder performance evaluation.

The business operates as a B2B professional services firm with project-based, quote-driven pricing and no publicly disclosed rates. Go-to-market is sales-led, relying on direct relationships with Texas asphalt contractors and producers, state and local government transportation agencies (notably TxDOT), and Texas municipalities. Distribution is direct from the single San Marcos lab, supplemented by on-site field work. Marketing channels center on active participation in industry associations — TxAPA, AGC of Texas, NAPA, AAPT, SEAUPG, and Women of Asphalt Texas — and on leadership roles within TxAPA committees, including the Professional Engineering Services Committee and Specification Committee.

In 2024 the company was acquired by Certerra and now operates as the Materials Engineering and Earth Sciences division of that parent brand. Leadership comprises President Stacy L. Rowh (P.E., M.Eng., ~25 years of pavement engineering experience, formerly technical director at a major Texas asphalt producer and research engineer at the Texas A&M Transportation Institute), Vice President Ryan Pryor (20 years of business development experience), and Business Development Advisor Nathali Parker (20+ years across sales, project management, and marketing; charter member of Women of Asphalt Texas and Chair of the Governor's Commission for Women). Headcount is reported at 1-10 employees, revenue is not publicly disclosed, and the company is privately held.
