Low noise diamond ground pavement surfaces deliver high-performance on Australia’s newest major motorway The recently opened M12 Motorway, 45 km west of Sydney Central Business District, allows high-speed traffic to travel from the M7 Motorway to The Northern Road in the western suburbs in a growing area of Sydney. More importantly, it is a vital gateway to the new 24-hour Western Sydney International Airport. The motorway consists of two carriageways with two 3.5 m-wide lane

WASHINGTON'S SPS-2 TEST SECTIONS ARE NOW 31 YEARS OLD! You Are Invited: The Washington Department of Transportation, LTPP, and IGGA/ACPA invite you to participate in an SPS-2Tech Day Event. You will learn about the results of the largest concrete pavement experiment ever undertaken. This is a unique opportunity to learn about and evaluate firsthand the performance of a national concrete pavement experiment. Celebrate this learning experience with us on: June 11th, 2026 - 9:00

How physical road properties unlock major energy savings MIT research reveals that road design and maintenance impact transportation emissions far more than construction materials. According to Hessam AzariJafari of the MIT Concrete Sustainability Hub, the industry has focused heavily on vehicle efficiency while paying far less attention to the roads those vehicles travel on. That gap may overlook one of the largest energy-saving opportunities in transportation. MIT research

By NICK DAVIS International Grooving and Grinding Association Highway departments face tight budgets and staff shortages while often resorting to costly and invasive “worst-first” repairs. Concrete pavement preservation (CPP) techniques offer an alternative solution by addressing minor issues before they become larger, more expensive problems, and ultimately save billions of dollars for highway agencies. In the early 2000s, the Washington State Department of Transportation (W

A repair material that addresses both short-term demands and long-term objectives Maintaining concrete pavements requires efficient repair strategies to minimize operational downtime. Partial depth repair involves removing isolated areas of a compromised pavement slab and replacing the material to restore surface integrity. Calcium sulfoaluminate (CSA) cement is an advanced cementitious material that provides a highly effective solution for these isolated restorations. CSA

Work on Phoenix highways will save $4B in life-cycle resurfacing costs Photo courtesy of Diamond Surface Inc. More than a decade ago, a pavement rehabilitation process called Buried Treasure started gaining momentum. This preservation concept is a technique used to recover an otherwise structurally sound concrete pavement that was overlaid due to functional deficiencies, such as excessive noise or poor ride. Today, the Buried Treasure strategy is helping states across the co

Exploring data on acoustic longevity A 2009 report published by the American Concrete Pavement Association, "Transportation Noise and Concrete Pavements," remains relevant today with transportation noise continuing to be a critical quality-of-life issue and a primary constraint in highway infrastructure design. Managing acoustic impacts while maintaining project budgets, safety standards and collaborative timelines requires a rigorous evaluation of pavement surface technologi

Discover concrete preservation techniques to extend service life and improve safety The architecture, engineering and construction industry is currently navigating a significant trend of escalating costs across highway infrastructure projects. According to Pew, "States are facing an $86 billion shortfall over the next decade for maintaining roads and bridges. And the U.S. is among the most expensive countries for transportation construction; projects typically cost more than
