Tri-State Paving’s quality control team has developed a safer and more practical method to trimming density cores. Eight cores are typically drilled out of the road each morning from the previous day’s production and brought back to the lab to test the asphalt’s density. To measure the density, the uneven edge on the bottom of the cores must first be trimmed using a core saw. Eight cores are trimmed and tested to obtain a consistent sample.

Previously, core saw operators had to hold the asphalt core with his hand while the blade trimmed the core. This method presented a significant hazard as the operator’s hand was often only inches from the blade. Tri-State Paving’s quality control team recognized the danger in continuing operation of the core saw in this manner, so they put their heads together to brainstorm ideas for a safer solution.

Essentially a large, orange clamp, the new device allows the operator the ability stabilize the core while keeping his hands a safe distance from the blade. The clamp also eliminates the possibility of the saw pulling the core out of the operator’s hands and damaging the core. After an entire season of use, it is evident that the modified device is much more safe and practical than the original core saw.
