Green Concrete

By recycling concrete and producing crushed concrete aggregate closer to where it will be used, the cost of transportation is lower, helping keep the cost of concrete lower. Coming up with new, innovative ways to make a greener concrete will benefit all of us in one way or another.

Paving

Our company was founded on quality concrete paving. It's what the Zignego brothers built their business on in 1954, and it's a service we continue to provide today. We pave and patch roadways and parking lots, build barrier walls, install sidewalks, move earthwork, recycle existing pavements, and crush materials to produce new aggregates.

Asphalt Vs. Concrete — Which is Better for You?!?

Asphalt is a by Product of Oil so Concrete is "Greener". This statement is a win/win for both asphalt and concrete. That is correct. Asphalt is a byproduct of oil. When refineries are making diesel and gasoline to fuel our vehicles the "liquid asphalt" that is left over is used to make Asphalt in Asphalt Plants.

Chapter 3 Pavement Patching and Repair

Flexible pavements generally are referred to as asphaltic concrete pavement (ACP) or bituminous surface treatment (BST). Flexible pavements develop strength from the tight interlocking of crushed rocks with an asphalt material binding them together. This mixture deflects when loaded by traffic and exerts pressure on the subgrade.
