SMA Mix, Connecticut

Details

Peckham Industries is proud to supply the first-ever Stone Matrix Asphalt (SMA) mix in Connecticut, providing the materials for a landmark I-95 rehabilitation project in Fairfield County. Partnering with Waters Construction and the Connecticut Department of Transportation (CTDOT), Peckham is delivering the SMA that will set a new standard for durability and performance on one of the state’s busiest highways.

The project involves milling and resurfacing with a Binder Rich Interlayer Course (BRIC) topped by SMA. Additional work includes bridge rehabilitation, drainage upgrades, and traffic system improvements. Peckham’s role is to provide the high-quality asphalt mix designed for strength, safety, and longevity at the heart of this milestone project. By supplying SMA for I-95, Peckham is bringing this proven technology to Connecticut for the very first time. In Connecticut, where the climate is characterized by cold winters, potential freeze-thaw cycles, and varying precipitation, Stone Matrix Asphalt (SMA) offers several advantages tailored to these conditions:

1. Freeze-Thaw Resistance: SMA’s dense composition and high asphalt binder content help resist the effects of freeze-thaw cycles. This reduces the likelihood of cracking and pothole formation, which are common issues in regions with cold winters.

2. Cold Weather Performance: The flexibility provided by the higher binder content in SMA mixes allows the pavement to better accommodate temperature fluctuations without cracking, which is particularly important in Connecticut’s fluctuating temperatures.

3. Moisture Resistance: Connecticut experiences a significant amount of precipitation, and SMA’s dense structure minimizes water infiltration, reducing the risk of moisture-related damage such as stripping and weakening of the pavement structure.

4. Snow and Ice Management: The texture of SMA can improve traction during snowy or icy conditions, enhancing safety. Additionally, the surface allows for more efficient snowplow operations.

5. Durability in High Traffic Areas: In urban and suburban areas of Connecticut with high traffic volumes, SMA’s resistance to rutting and deformation ensures a longer-lasting pavement structure, reducing the need for frequent maintenance and repairs.

6. Adaptation to Local Aggregates: SMA can be designed using locally sourced aggregates, which can be beneficial for projects in Connecticut, both in terms of cost-effectiveness and environmental impact.

SMA is an excellent choice for ensuring long-lasting, resilient pavement in Connecticut’s challenging climate. Its durability, moisture resistance, and performance under freeze-thaw conditions make it well-suited for the region’s roads and highways. For Connecticut drivers, SMA delivers smoother, safer and longer-lasting roads.

Supplying SMA for I-95 is more than just a milestone—it’s part of Peckham’s ongoing commitment to building better roads, supporting local communities, and leading with innovation.
