Base stabilization increases the bearing capacity and strength of the roadway. Cement Treated Base (CTB) or Cement Treated Sub-Base (CTSB) have been common and popular methods to stabilize the soil and aggregate layers in paving applications. However, another method is gaining wider use. An Emulsion Treated Base (ETB) is an aggregate stabilized with emulsion and cement. Adding an emulsified [...]
Crude oil is sourced from locations around the globe. Fuel refineries then further alter bitumen characteristics. Crude slate blending, and bitumen blending, add another layer of variability to the nature of the product. All of these factors result in a collective issue of “quality” in bitumen, resulting in a commodity that varies widely in composition and properties. Because of [...]
