Methods for sealing cracks and expansion joints comprising the use of an adhesion promoter. In certain embodiments, the adhesion promoter comprises a vinyl polymer.

A layered material includes a first carrier material and a second carrier material. The first carrier material is coated or saturated with a modified bitumen. The modified bitumen is a bitumen to which is added an agent selected from a wax, a silicone oil, stearic acid, alkene ketene dimer (AKD), alkenyl succinic anhydride (ASA), and mixtures thereof. The first carrier material is continuously attached to the second carrier material.

Plastomer-modified asphalt binders meeting MSCR specifications, asphalt paving materials with such asphalt binders, and methods for fabricating such asphalt binders are provided. The asphalt binder contains a base asphalt and a plastomer. If the plastomer has a drop point no greater than about 139° C., the asphalt binder further contains sulfur; sulfur-containing compounds, such as hydrocarbyl polysulfides and thiuram disulfides; phenolic resins; metal oxides; or a combination thereof. The asphalt binder is substantially free of elastomer.

Materials and methods for mitigating passive intermodulation. A membrane for reducing passive intermodulation includes a first polymeric layer, a second polymeric layer, and a continuous metal layer encapsulated between the first and second polymeric layers. A self-adhesive radio frequency barrier tape includes a waterproof polymeric top layer, a metal-containing layer adhered by an adhesive layer to the polymeric top layer, a pressure sensitive adhesive layer adhered to the metal-containing layer, and a release liner on a bottom surface of the pressure sensitive adhesive layer. A method of mitigating passive intermodulation includes passing a probe over an area of interest, the probe being sensitive to an intermodulation frequency of interest, and identifying a suspected source of passive intermodulation when the amplitude of the probe output exceeds a threshold at the frequency of interest. The method further includes covering the suspected passive intermodulation source with a radio frequency barrier material.

Disclosed are methods for preparing a high-viscosity non-hazardous bitumen composition for transportation in a railcar, wherein the method may include: (a) providing to a fractionator system a low-viscosity bitumen composition previously residing in a pipeline having a first viscosity and comprising a miscible blend of hydrocarbons, which blend was prepared by mixing a first diluent composition with a first bitumen composition; (b) heating the low-viscosity bitumen composition in the fractionator system at an operating temperature of from 170 C to 232 C to provide a first light fraction and a first heavy fraction; (c) removing at least a portion of the first heavy fraction from the fractionator system, wherein the first heavy fraction has a second viscosity that is higher than the first viscosity; (d) forming a high-viscosity non-hazardous bitumen composition from at least a portion of the first heavy fraction; and (e) directing the high-viscosity non-hazardous bitumen composition to a railcar.
