Quality: A Top Priority At Blue Diamond Materials

At Blue Diamond Materials, we are extremely conscious of our impact on the environment.

Asphalt Recycling

We recycle thousands of tons of asphalt pavement each year, saving valuable materials from landfills, and conserving virgin aggregates. This practice reuses the petroleum fraction of our product by reusing the “glue” as new binder material from the original product. This direct reuse reduces the demand for oil imports and produces a product equally to, and in some ways superior to 100% virgin asphalt pavement.

Power Savings

We’ve also pioneered the uses of variable frequency drive motors on asphalt plants, which reduces our electrical demand and consumption.

Eco-Friendly Production

Blue Diamond Materials is leading the efforts to introduce EcoMat® Warm Mix Asphalt technology to the Los Angeles Basin and surrounding areas. This process reduces the energy needed to heat asphalt mixes, reduces emissions at both the plant and the job-site, and ultimately increases the performance of pavement.
