Method for monitoring bituminous material
A method by computer useful for monitoring the environmental characteristics of bituminous material that is used in an industrial process. Disclosed is a particularly useful method for the processing of asphalt when a transport takes the bituminous material under its control. The method being capable of communicating environmental information related to the material as observed by the transport and the users involved in the industrial process.
FLUXING AGENTS FOR HYDROCARBON BINDERS
The invention relates to the use, as fluxing agent for bitumen compositions, of at least one compound having the formula (I)
R.sup.1C(O)OR.sup.2 (I) where: each of R.sup.1 and R.sup.2, which may be identical or different, is a linear or branched hydrocarbon chain which does not carry an unsaturated covalent bond, optionally interrupted by one or more oxygen atoms, and optionally carrying one or more hydroxyl functions.
Bituminous composition solid at ambient temperature
A bituminous composition comprising at least one bitumen base, at least one compound of general formula (I): Ar1-R.sub.1Ar.sub.2 (I), and at least one compound of general formula (II): R.sub.2(NH).sub.nCONHX(NHCO).sub.p(NH).sub.nR.sub.2 (II). The invention also concerns a process for the preparation of said bituminous composition.
PAVING-RELATED MEASURING DEVICE INCORPORATING A COMPUTER DEVICE AND COMMUNICATION ELEMENT THEREBETWEEN AND ASSOCIATED METHOD
A system configured to determine a property of a paving-related material is provided. The system includes a measuring device configured for measuring a property of a paving-related material and a cellular computer device configured for being in communication with and receiving data from the measuring device.
SYSTEM AND METHOD FOR REDUCING VISCOSITY VARIATIONS IN ROOFING ASPHALT
An asphalt shingle coating system that includes a coater, a mixer, a viscosity gauge, a wax supply, a wax pump and a control system. The coater applies a layer of a coating asphalt mixture on an asphalt shingle substrate. The mixer mixes the coating asphalt mixture and is positioned upstream of the coater. The viscosity gauge may be positioned between the coater and the mixer, and it measures the viscosity of said coating asphalt mixture before it is delivered to the coater. The wax supply is in fluid communication with the mixer and a wax pump may deliver a volume of wax from the wax supply to the mixer, and the control system may selectively adjust the operation of the wax pump to substantially maintain a desired viscosity of said coating asphalt mixture.
ASPHALT BINDERS AND RELATED METHODS AND USES
Asphalt binders and related methods and uses are provided. In some embodiments, the asphalt binder is produced by: providing a high-asphaltene content petroleum feedstock; performing solvent deasphalting on the feedstock to produce a partially deasphalted oil and an asphaltene-rich residue; and collecting the partially deasphalted oil (DAO). The high-asphaltene content petroleum feedstock may comprise residue from vacuum distillation or flash separation of extra heavy oil or bitumen, or recycled asphalt. The DAO may itself be used as the asphalt binder or may be a component of a blend with the original feedstock. Asphalt binders may also be produced by blending residue and heavy distillate produced from vacuum distillation or flash separation, with DAO or the asphaltene-rich residue of the solvent deasphalting process. The disclosed methods allow for production of asphalt binders of a wide variety of performance grades.
Crude sterol as an additive in asphalt binder
Disclosed are binders and methods for making such binders with crude sterols. The crude sterols improve various rheological properties of the binders. The disclosure provides a method for slowing the aging rate of aged asphalt binder comprising adding a crude sterol to an asphalt binder, wherein the asphalt binder comprises both virgin asphalt binder, and reclaimed asphalt binder material comprising asphalt pavement (RAP), asphalt shingles (RAS) or combinations of RAP and RAS.
