Asphalt has many uses, but we bet you didn’t know that mumification was one of them! In fact, the word “mummy” comes from the Greek word for asphalt bitumen, “mumia.” Better let us test your #Halloween costumes to make sure they’re accurate! 😉🎃 #ChicagoTestingLab #CTL

🎃 #Halloween brings more than costumes and candy — it brings busy streets, low light, and distracted drivers. Whether you’re heading home from work or through a neighborhood full of trick-or-treaters, take a minute to check your own safety habits. #CTL #RoadwaySafety

Small stones; big impact. This is one of the reasons testing is so vital: we need to ensure the aggregate size, shape, and gradation is correct for the intended use. Did YOU know this? #ChicagoTestingLab #CTL #AggregateTesting #MaterialsMatter #ConstructionSupport
