Dry Process Crumb Rubber Modifier
Crumb Rubber ASPHALT Technology
What is DPCRM Rubber Asphalt?
Dry Prcoess Crumb Rubber Modifier (DPCRM) is an innovative solution rooted in established technology that’s gaining renewed traction across the U.S. It’s created by grinding whole scrap automobile tires into crumb rubber, which is then incorporated into asphalt mixes and laid during paving. As the largest market for recycled tires, rubberized asphalt puts approximately 220 million pounds—or around 12 million tires—to use each year. With rising interest, more states are rediscovering and refining this method to meet modern infrastructure demands.
Why Choose DPCRM Rubber Asphalt?
DPCRM, which stands for Dry Process Crumb Rubber Asphalt Modifier, is a hot mix asphalt modification solution—distinct from traditional liquid additives. Over 4 million tons of DPCRM-enhanced asphalt have delivered exceptional performance in some of the most demanding climates and traffic conditions for more than a decade.
Compared to polymer-modified asphalt, DPCRM offers a range of plant-side benefits. Polymer mixes can be sticky and problematic to handle, often leading to slower production and system buildup. In contrast, DPCRM runs clean through your plant, improving efficiency and reducing operational headaches.
Key Advantages of DPCRM:
- Cost-Effective Performance Upgrade: Delivers enhanced binder properties comparable to polymer modification while reducing material costs
- Production Efficiency: Lower mix viscosity means improved plant throughput and easier handling compared to traditional polymer systems
- Cleaner Operations: Mix releases cleanly from truck beds, minimizing residue and reducing cleanup time
- Simplified Compaction: Workable mix characteristics help crews achieve density specifications efficiently
- Thin-Lift Performance: Well-suited for overlay and preservation applications where maximizing durability in reduced thicknesses is critical

DPCRM: Better Roads at Lower Cost
Today’s road managers—especially in the public sector—face the challenge of maximizing results with limited budgets. DPCRM offers a smart solution. Its lower production costs compared to polymer-modified alternatives often translate to lower project bids. That means longer-lasting roads delivered at a better value.
Incorporating DPCRM into your process is simple. The rubber modifier is metered into the production process alongside other mix components, requiring no additional blending infrastructure. It reacts with the heated asphalt binder during mixing, storage, and transport, resulting in a mix that performs like a polymer-modified pavement, but at a fraction of the cost.
Here is how the DPCRM process works:
DPCRM integrates into your existing hot mix production process without specialized equipment. The rubber particles interact with the asphalt binder during mixing and transport, producing a modified pavement that rivals polymer performance at a lower cost.
Traditional crumb rubber modification methods have faced challenges with cost, equipment requirements, and production complexity. Dry-process technology addresses these barriers by allowing rubber to be incorporated during standard mix production, making rubberized asphalt accessible to a wider range of producers and projects.
