Warm mix asphalt technology has reshaped how road construction projects approach temperature-sensitive paving, especially when combined with rubberized binders. On California’s Highway 1 along the Mendocino Coast, Caltrans demonstrated that pairing warm mix additives with asphalt-rubber gap-graded (RHMA-G) mixes can overcome challenging environmental conditions while delivering durable, long-lasting pavements. This project proved that modern stone […]

Extending the service life of paved roads while controlling maintenance budgets is a constant challenge for transportation agencies and contractors alike. One pavement preservation technique that has proven remarkably effective is the combined use of fog seal over chip seal surfaces. This approach, widely adopted in states such as South Dakota, delivers measurable benefits including

Understanding Your Fleet Fuel Consumption Patterns Developing an effective refueling strategy begins with a clear understanding of how your fleet actually consumes fuel. Equipment size, engine horsepower, duty cycles, and project location all influence fuel demand, and each factor must be evaluated before selecting a fueling approach. A one-size-fits-all method rarely works for construction fleets,

The pavement maintenance industry has undergone a remarkable transformation over the past quarter century, driven by innovations in equipment design, material science, and operational efficiency. From larger sealcoating tanks to automated layout systems, contractors now have access to tools that dramatically improve productivity and profitability. This article explores six key innovations that have reshaped how

Specifying a medium- or heavy-duty truck for construction work is far from a simple process. Every option selected from the manufacturer’s checklist affects the vehicle’s weight, cost, and productivity on the job site. For contractors operating Class 7 and Class 8 vocational trucks, finding the right balance between payload capacity, durability, and driver comfort can

Pavement maintenance contractors are increasingly encountering projects that require familiarity with the Leadership in Energy and Environmental Design framework. LEED certification has become a defining benchmark in sustainable construction, influencing everything from material selection to site design. For contractors working in paving, parking lots, and asphalt applications, understanding how LEED credits apply to pavement work

Coordinating asphalt milling and paving operations in a busy urban environment presents challenges that rural or suburban projects rarely encounter. When the streets themselves serve as the lifeline for a city’s historic business district, contractors must balance construction efficiency with minimal disruption to commerce, tourism, and daily life. One project that demonstrates how to meet

In road construction and pavement maintenance, the efficiency of the paving train often depends on the smallest details. One such detail, the humble sweeper broom, became the focus of an innovative field modification that transformed a Pennsylvania Department of Transportation (PennDOT) milling and paving operation. When a standard 5-foot broom proved too wide for a

Construction fleet managers face an increasingly complex decision when selecting fuel types for heavy trucks. With diesel prices fluctuating and environmental regulations tightening, many are turning to natural gas alternatives. Two primary options have emerged: compressed natural gas (CNG) and liquefied natural gas (LNG). While both offer lower emissions compared to diesel, they differ significantly

When Granite Construction secured the resurfacing and repaving contract on Interstate 90 just east of Snoqualmie Pass in Washington State, the project presented an unusual combination of challenges. The roadway endures some of the harshest wear conditions of any Washington state highway due to extreme temperature fluctuations and heavy truck traffic. The project itself required
