The American Recovery and Reinvestment Act (ARRA) of 2009 represented one of the largest federal investments in public infrastructure since the interstate highway system. For construction contractors across the United States, this legislation channeled billions of dollars into roads, bridges, water systems, public buildings, and Energy Recovery Ventilation Systems that improved building efficiency in federally […]

When a paving contractor faces a 31-day deadline for what would normally take 90 days, every piece of equipment and every technique on the job site must perform at its peak. This was the reality for O&G Industries Inc. of Torrington, Connecticut, when it was contracted to place a new asphalt surface on the iconic

As municipalities across North America shift from production-based compaction specifications to density-based requirements, contractors face new challenges in achieving consistent, verifiable results. The move from measuring compaction by tons per hour per roller to requiring minimum percentages of laboratory density has forced paving professionals to reevaluate their equipment choices and rolling patterns. One technology that

Asphalt Pavement Engineering Mix Design Construction Methods Rehabilitation represents the foundation of modern road infrastructure. Pavement rehabilitation and preservation extend the service life of existing pavements while reducing the need for costly full-depth reconstruction. From milling machines that remove deteriorated surfaces to infrared heaters for seamless patching, the equipment used in these operations continues to

In the summer of 2005, Champaign County, Illinois, embarked on an ambitious experimental pavement reconstruction project on County Road 9 that would test the viability of foamed asphalt technology for low-volume, heavy-load rural roads. Home to both rustic farm roads and the sprawling University of Illinois campus, the county needed a cost-effective alternative to traditional

Pavement preservation requires a coordinated approach that combines effective materials, specialized equipment, and sound construction practices. The February 2006 lineup of preservation products showcases innovations that continue to influence modern pavement maintenance strategies. From rapid-curing tack coats to high-capacity road reclaimers and efficient pothole patching systems, these tools address the core challenges of extending pavement

The California Department of Transportation and its private-sector partners demonstrated what is possible when innovation meets infrastructure when they rehabilitated a major section of Interstate 80 through the Sierra Nevada using cold in-place foamed asphalt recycling. This project, spanning nearly 27 miles of traffic lanes from Auburn to Colfax, saved California taxpayers over $1 million

Compaction is one of the most critical operations on any construction site, affecting the long-term performance of roads, foundations, and structures. Whether working with soil or asphalt, achieving proper density requires understanding material behavior, equipment capabilities, and environmental conditions. Recent advances in heavy roller technology have transformed compaction from an art reliant on operator experience

For construction fleet operators, the difference between a profitable year and a costly one often comes down to preventive maintenance. Among the most valuable yet underutilized tools in a fleet manager’s arsenal is routine oil analysis. This practice, which involves systematically testing used engine oil for contaminants and wear metals, can detect problems long before
