A Song Of Fire(not ice)

We have now re-tested the Dreamy Draw project 1 year after and the results are encouraging. 

‍The results: 

On average 50% stronger road and at least 100% stronger parking lot than before the Carbon Crusher method was utilized.

Project Overview

The testing took place at the Dreamy Draw Recreational Area in Phoenix and involved two main areas:

1. Parking Lot: An unsurfaced area made of native soil.

2. Road Segment: A 600-foot section of road with varying thicknesses of asphalt.

The goal was to see how well the CarbonBioBinder could improve the strength (stiffness) of these areas during and after construction, especially under high temperatures reaching up to 120°F (with surface temperatures up to 150°F).

Testing Methods

Applied Research Associates, Inc. (ARA) conducted the testing using two devices:

‍

1. Falling Weight Deflectometer (FWD):

• Used on the road segment.

• Simulates the effect of traffic loads on the pavement.

• Measures how much the pavement deflects (bends) under a load similar to that of passing vehicles.

‍

2. Light Weight Deflectometer (LWD):

• Used on the parking lot area.

• Measures deflection to assess soil and pavement stiffness.

• Helpful for quality control during construction, especially for layers like subgrade and subbase.

‍

And this is how our customers feel: 

"The City of Phoenix celebrates the completion of its inaugural project in partnership with Carbon Crusher, marking a monumental milestone. Together, we have achieved the remarkable feat of sequestering CO2 directly in the upgraded road and parking lot in Dreamy Draw Recreation Area. This project epitomizes our unwavering commitment to both quality and environmental stewardship in our cherished recreational areas.”

Testing Approach

• Before Treatment: ARA measured the initial stiffness and deflection of both the parking lot and road segment to establish a baseline.

• During Construction: They took measurements after each compaction pass to monitor improvements in stiffness.

• After Treatment: Final measurements were taken after the Biobinder was applied and had time to cure (up to 18 days) to see the overall improvement.

‍

Results

• Road Segment:

• After applying ourCarbonBioBinder and allowing it to cure, the pavement showed reduced deflection. This means it became stiffer and could better withstand loads.

• Deflection measurements became more consistent along the road, indicating uniform improvement.

On average 50% stronger than previous

• Parking Lot:

• Initially had higher deflection due to being native soil.

• After treatment and curing, deflection decreased significantly, showing that the Biobinder improved the soil’s stiffness.

• Despite the extreme heat, the Biobinder was effective.

At least 100% stronger than previous

Conclusion

The Curshing and full depth reclamation with on site reuse of material together with our Biobinder has successfully increased the stiffness of both the parking lot and road segment in the hot climate of Phoenix, Arizona. This suggests that our sustainable material can be effective in both cold and hot environments. If widely adopted, this Biobinder could play a significant role in building more sustainable and durable roads.
