Barnes Barton Takes Over at Pavement Preservation Group — and What That Means for the Infrastructure Story You Can Invest In

Barnes Barton takes the helm at Pavement Preservation Group, replacing the man who built the platform. For a retail investor, the headline carries a different question than a trade: what is this private company doing, and where does it fit in the broader infrastructure investing picture?

PPG is not a public company. It is a portfolio company of The Sterling Group, a Houston-based middle-market private equity firm with roughly $9.4 billion in assets under management. You cannot buy shares. But the leadership change tells you something about the lifecycle of the business and the direction the pavement preservation sector is heading — both of which are worth understanding if you hold, or want to hold, exposure to the companies that maintain America's roads.

The platform being built

In May 2025, Sterling acquired two regional operators — Arizona-headquartered Pavement Preservation Group, Inc. and Kansas City's Vance Brothers, LLC — and merged them under the PPG banner. Darin Matson, a former CEO of Rogers Group (the largest privately owned aggregates producer in the United States), came out of retirement to run the platform. That was a founder's hire: Matson brought sector relationships and name recognition to stitch two independent operations into a national platform.

Then came the add-on acquisitions, which is where the private equity engine takes over. Circle C Paving in October 2025. Holbrook Asphalt and Integrated Pavement Solutions in January 2026. Asphalt Paving Systems — a vertically integrated contractor with manufacturing — in May 2026. Five acquisitions in little more than a year. The geographic map is expanding from the Southwest and Midwest into the Intermountain West, the Southeast, and the East Coast.

The services are not glamorous but they are structurally in demand. PPG's divisions do scrub sealing, fog sealing, chip sealing, slurry sealing, microsurfacing, and crack sealing. These are the treatments that extend the life of existing asphalt roads without the cost and disruption of full reconstruction. The National Park Service notes that a dollar spent on pavement preservation can save between $6 and $10 in future rehabilitation costs. For state DOTs and municipal highway departments — the customers — that math is hard to ignore when budgets are stretched.

Why the CEO changes now

Matson served about 14 months, which Sterling called a "formative period". His job was done: the platform was assembled, the divisions were in place, the acquisition pipeline was established. Now Sterling needs an operating CEO who can run the combined company, not just build it.

That is where Barnes Barton fits. He spent 16 years at CRH Americas Materials — the publicly traded building materials giant on the NYSE — most recently as President of the South Division. Before CRH, he was President at Harrison Construction and Vice President at APAC-Atlantic. Over 20 years in construction materials and asphalt operations.

Barton already knew Sterling. He served on the board of Frontline Road Safety, another Sterling portfolio company, from 2023 until its sale to Bain Capital in 2025. Sterling Partner Brad Staller cited Barton's "operating track record" and experience leading regional platforms. The trust was already there; the relationship was not cold.

This is a textbook private equity transition. Foundational CEO builds the platform. Operational CEO scales it and prepares it for exit. The next act for PPG is not another merger announcement — it is running the combined entity, integrating five distinct operations, and proving the platform generates consolidated cash flow at scale.

The tailwind under the pavement

The sector PPG operates in sits under one of the most durable spending commitments in recent history. The Infrastructure Investment and Jobs Act — $1.2 trillion enacted in 2021 — allocated $350 billion to highway programs over five years and $85 billion to bridges. The funding window runs through 2026. States spent roughly $247 billion on roads and bridges in fiscal year 2024, according to Pew research, and that figure falls short of what is needed. Thirty-nine percent of major U.S. roads are in poor or mediocre condition.

The demand side is not a question mark. The question is execution. Can a consolidated platform manage five regional cultures, harmonize operations, and deliver margin improvement without disrupting the municipal contracts that are the revenue engine? That is the work an operating CEO like Barton is hired to do. And it is the work Sterling will judge before deciding whether to hold, sell, or take the platform public.

Where retail investors fit

PPG itself is not investable. But the same forces driving Sterling's build-out in pavement preservation are visible in publicly traded companies right now.

CRH — the company Barton spent 16 years at — is the closest publicly traded proxy. It is the world's largest building materials supplier, with extensive U.S. exposure through CRH Americas Materials. The company generates $2.8 billion in free cash flow over the trailing twelve months, produces a 1.7% dividend yield backed by a 19-year payout history, and trades at roughly 16 times trailing earnings. Its free cash flow grew 26% year over year. The stock has been under pressure this year, down roughly 26% year-to-date, trading near $92 — well below its 52-week high of $132.

That pullback is worth noting. CRH benefits from the same infrastructure spending tailwind that makes PPG's business attractive to private equity. The IIJA funding, water system upgrades, and industrial buildouts that Sterling identified as a platform opportunity are also flowing through CRH's asphalt and aggregates operations. The company's gross margin sits at 36%, operating margin at 14%, and return on invested capital at 10.3%. These are the numbers that show a capital-intensive business running at healthy efficiency.

The difference between CRH and PPG is not the sector — it is the capital structure. CRH is a public company with $33 billion in total debt, $3 billion in cash, and a net debt-to-equity ratio of 0.70. Sterling's PPG is leveraged the way all private equity portfolio companies are: built on acquisition debt, with an exit horizon of three to five years that drives every operational decision.

The real takeaway

A CEO change at a private company is not a trade signal. But it is a signal about the maturity of the platform and the confidence of its sponsors. Sterling did not keep a transitional founder-CEO in place. They brought in an operational leader with deep sector experience and an existing relationship with the firm. The message is that the building phase is over and the operating phase has begun.

For retail investors, the useful move is not to chase a company you cannot buy. It is to recognize that private equity sees structural demand in pavement preservation and has spent over $25 billion across 78 platform companies building exactly this kind of national consolidation play. If the thesis holds — and the spending commitments suggest it does — the publicly traded companies in the same supply chain carry the same tailwind, with the advantage of transparency, liquidity, and a dividend you can count on today.

The risk, on both sides, is execution. A private equity platform that cannot integrate five regional operators will not compound. A public company like CRH that cannot convert infrastructure spending into sustained cash flow will not reward patience. The spending is the given. The operational result is not.
