Our Commitment to Sustainability
At Central Washington Asphalt, environmental responsibility is built into every project. We focus on practical, measurable actions that protect local communities while delivering the high-grade pavement performance our regional partners expect.
Our Core Pillars
Reducing Waste
High-RAP mix designs that minimize landfill waste and cut down on virgin oil consumption.
Conserving Resources
Fuel-efficient plant operations and localized aggregate sourcing across our facilities.
Supporting Our Environment
High-spec mixes developed in our Quality Control labs for maximum rut resistance and structural strength
Recycled Asphalt Pavement (RAP)
Recycling asphalt is one of the most effective ways to reduce environmental impact in pavement production. Central Washington Asphalt incorporates Recycled Asphalt Pavement (RAP) into our mix designs whenever project specifications and material conditions allow.
Our RAP Approach
Typical RAP Content:
Central Washington Asphalt generally incorporates around 20% RAP, consistent with the standard percentage allowed by State DOT guidelines.
State‑Specific Compliance:
When producing asphalt in Washington, Idaho or Oregon, we follow each state's applicable RAP guidelines and allowable limits.
Higher‑Recycled Mixes:
For private projects, select hot plants can produce mixes with higher RAP content—up to 40% where specifications permit.
Quality Monitoring:
Our Quality Management group develops Hot Mix Asphalt (HMA) designs focused on sustainability and long-term structural value.
Sustainable Mix Design Engineered in the Lab, Built on the Road
Key Principles
- Custom mix formulations are precise-engineered to meet or exceed state DOT structural standards.
- Mixes are engineered to balance load-bearing capacity, pavement flexibility, and responsible material use.
- Lab-tested formulations preserve mix workability and compaction efficiency for seamless installation on the job site.
- This approach supports both environmental responsibility and extended pavement longevity.
