Asphalt Surfaces

Arcosa Lightweight’s expanded shale and clay aggregates offer a high-performance solution for asphalt applications, providing superior skid resistance, reduced rutting, and improved durability for road surfaces.

By incorporating lightweight aggregates, asphalt surfaces gain resilience against wear and tear, increased longevity, and improved safety for drivers in both urban and rural settings.

Key Benefits

Arcosa Lightweight aggregates in asphalt surfaces provide enhanced skid resistance, reduce rutting and surface deformation, and offer long-lasting durability, making roads safer and more cost-effective to maintain.

Improved Skid Resistance and Safety

Lightweight aggregates used in chip seals and surface treatments create a rough, textured surface that enhances skid resistance, providing safer driving conditions, especially in wet weather. This characteristic makes Arcosa aggregates ideal for high-traffic roads and intersections.

Reduced Rutting and Surface Deformation

The unique angularity and hardness of Arcosa Lightweight aggregates help distribute loads more evenly, reducing rutting and surface deformation under heavy traffic. This quality results in longer-lasting, low-maintenance asphalt surfaces.

Enhanced Durability and Cost Efficiency

Arcosa aggregates are durable and resistant to moisture and freeze-thaw cycles, extending the life of asphalt surfaces and reducing the need for frequent repairs. This durability lowers maintenance costs over time, making them a cost-effective choice for road construction and rehabilitation.

Featured Case Studies

Arcosa Lightweight’s Streetman Product Has Highest Polish Value in Texas

It’s estimated that over 300,000 cubic yards of lightweight aggregate is used each year in Texas for seal coat and surface treatment applications. Arcosa Lightweight’s Streetman product boasts the highest polish value of any material used in Texas, based on TxDOT’s Bituminous Rated Source Quality Catalog (BRSQC).

Lightweight Aggregate Used as Ice Chat Improves Safety From Winter Weather

Wintry weather in North Texas can sometimes turn surprisingly extreme, leaving icy roads in its wake. That’s why the Texas Department of Transportation often blends lightweight expanded shale into a product they call “ice chat”.

Chipseal Delivers Economy, Longer Lasting Roads in Nebraska Project

State Highway 61, just south of Ogallala, Nebraska, often utilizes expanded shale lightweight aggregate from Arcosa Lightweight. “In this day and age, it’s all about preserving the life of the pavement,” says Matt Radke, former Maintenance Supervisor for the Nebraska Department of Transportation (NDOT).

Skid Resistance for Safety

The rough, angular surface of Arcosa aggregates increases skid resistance, providing a safer driving experience and reducing accidents in wet conditions.

Rutting and Deformation Resistance

Arcosa aggregates help distribute traffic loads, reducing rutting and maintaining a stable surface over time, ideal for both urban and rural roads.

Durable and Weather-Resistant

Resistant to moisture and freeze-thaw cycles, Arcosa Lightweight aggregates maintain integrity in various climates, extending the lifespan of asphalt surfaces.
