You may have heard of a new asphalt binder parameter for evaluating age-related cracking potential. Pronounced delta tea see, it’s spelled out ΔTc. It’s defined as the numerical difference between the low continuous grade temperature determined from the Bending Beam Rheometer (BBR) stiffness criteria (which is the temperature at which stiffness, S, equals 300 MPa) […]

The standards division of the city of Los Angeles developed a fast, simple, repeatable test with the Rutwheeler from Pine Instruments, Grove City, Pennsylvania, to predict permanent deformation and moisture susceptibility in hot-mix asphalt Superpave designs. The sprawling city of Los Angeles has approximately 6,500 centerline miles of roads and 800 centerline miles of alleys […]
