According to the present invention there is provided a method of treating timber with a creosote-containing preservative formulation adapted for use at substantially ambient temperature. The formulation comprises: creosote; one or more surfactants such that when diluted with a predetermined quantity of water, the creosote is present as an oil-in-water macroemulsion or microemulsion; and optionally, an anti-foaming agent and/or a fire retardant. It is found empirically that the inventive concentrate allows for the use of creosote, a known-effective biocide, without many of the drawbacks inherent in such use.

Disclosed herein are rejuvenating compositions for asphalt applications. In one aspect, the rejuvenating composition comprises a polymerized oil having a polymeric distribution ranging from about 2 to about 80 wt % oligomer content and Hildebrand solubility ranging from about 6 to about 12. In another aspect, the rejuvenating composition comprises an oil having a Hildebrand solubility ranging from about 6 to about 12 and a flash point ranging from about 100 C. to about 400 C. In yet another aspect, the rejuvenating composition comprises a modified oil having a Hildebrand solubility ranging from about 6 to about 12 and a flash point ranging from about 100 C. to about 400 C.

Described herein is a polymerized biorenewable, previously modified, or functionalized oil, comprising a polymeric distribution having about 2 to about 80 wt % oligomer content, a polydispersity index ranging from about 1.30 to about 2.20, and sulfur content ranging from 0.001 wt % to about 8 wt %. Methods of manufacturing the polymerized oil as well as its incorporation into asphalt paving, roofing, and coating applications are also described.

Methods are provided for predicting the properties of an asphalt emulsion, such as an asphalt emulsion that contains an asphalt fraction derived from a plurality of crude oils. Corresponding tools are provided to allow for visualization of the predicted asphalt emulsion properties. The properties of the asphalt components in an asphalt fraction for forming an emulsion can be represented based on using a simplified functional form to represent each emulsion property of each asphalt component. The emulsion properties of an asphalt fraction, composed of a plurality of asphalt components, can be modeled based on a linear combination of the emulsion properties of the asphalt components.

A sealant material composition for sealing asphalt includes a non-fiber asphalt emulsion between about 20.0 wt. % and about 60.0 wt. %, carbon black between about 0.5 wt. % and about 5.0 wt. %, an aggregate between about 1.0 wt. % and about 10.0 wt. %, wherein the aggregate is amorphous aluminum silicate, and a hydrophobic additive between about 0.1 wt. % and about 1.0 wt. %.

It has been discovered that contaminants such as metals and/or amines can be transferred from a hydrocarbon phase to a water phase in an emulsion breaking process by using a composition that contains water-soluble C5-C12 polyhydroxy carboxylic acids, ammonium salts thereof, alkali metal salts thereof, and mixtures of all of these. The composition may also optionally include a mineral acid to reduce the pH of the desalter wash water. The method permits transfer of metals and/or amines into the aqueous phase with little or no hydrocarbon phase under-carry into the aqueous phase. Resolving the emulsion into the hydrocarbon phase and the aqueous phase occurs in a refinery desalting process using electrostatic coalescence. The composition is particularly useful in treating crude oil emulsions, and in removing calcium and other metals therefrom. The polyhydroxy carboxylic acid additionally inhibits metal corrosion of metal pipe or other equipment used in a crude unit.

Amines and amine derivatives that improve the buffering range, and/or reduce the chelation and other negative interactions of the buffer and the system to be buffered. The reaction of amines or polyamines with various molecules to form polyamines with differing pKa's will extend the buffering range, derivatives that result in polyamines that have the same pKa yields a greater buffering capacity. Derivatives that result in zwitterionic buffers improve yield by allowing a greater range of stability.

A composition for sealing and resurfacing a road surface includes a first material having at least a first emulsified asphalt, wherein the first material is applied to the road surface. The composition also includes a second material having a second emulsified asphalt and a driving surface material. The second material is applied to the first material such that the first material and the second material co-cure as a unified material.

A pavement repair system is provided utilizing solid phase auto regenerative cohesion and homogenization by liquid asphalt oligopolymerization technologies. The system is suitable for use in repairing asphalt pavement, including pavement exhibiting a high degree of deterioration (as manifested in the presence of potholes, cracks, ruts, or the like) as well as pavement that has been subject to previous repair and may comprise a substantial amount of dirt and other debris (e.g., chipped road paint or other damaged or disturbed surfacing materials). A system utilizing homogenization by liquid asphalt oligopolymerization is suitable for rejuvenating or repairing aged asphalt, thereby improving properties of the paving material.
