Martin Marietta Aggregates
By using Helix Steel, we were able to reduce the pavement thickness from 12" to 6".
– Capital Concrete
The Martin Marietta Aggregates were in the process of building a pavement at their Columbia, South Carolina facility. Having experienced failures of prior concrete pavements, Martin Marietta were looking for a reinforcement technology that could help concrete withstand high frequency, heavy loading without cracking or failure.
Capital Concrete worked with Helix Steel to design a pavement that has exceeded all expectations. By adding a dosage of 30lb/yd3, the team was able to reduce the pavement thickness by 50%. To date, the Helix Steel reinforced pavement is performing perfectly, even after pavement intact after 8 years and 2 million ESALs.
