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.
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.
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.
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.
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.
