A method may include introducing into a wellbore a resin-based sealant composition comprising: a resin comprising a cycloalkene; and a transition metal compound catalyst; and allowing the resin-based sealant composition to harden in the wellbore.

Foamed asphalt compositions, recycled asphalt compositions, asphalt pavement, and methods of forming asphalt pavement using the foamed asphalt compositions are provided herein. An exemplary foamed asphalt composition is in a cellular matrix form and includes a base asphalt component and oxidized high density polyethylene. An exemplary asphalt pavement includes a recycled asphalt layer that includes the foamed asphalt composition and a recycled asphalt component. An exemplary method of forming asphalt pavement includes combining a base asphalt component and an oxidized high density polyethylene to form an asphalt mixture. The asphalt mixture is foamed using water and compressed air to form a foamed asphalt composition. The foamed asphalt composition and a recycled asphalt component are combined to form a recycled asphalt composition. A recycled asphalt layer is formed with the recycled asphalt composition.

This document relates to methods for improving the tensile and elastic properties of cement of an oil well using cement compositions that contain sliding-ring polymer additives. The cement compositions containing the sliding-ring polymer additives exhibit increased stiffness while having a minimum impact on compressive strength, as compared to the same cement without the sliding-ring polymer additive.

A modified asphalt composition contains a bituminous component, a copolymeric thermoplastic elastomer (TPE), a high-cis homopolymeric polybutadiene rubber (BR) and a cross-linking agent. The modified asphalt composition exhibits improved low temperature flexibility (crack resistance), improved resistance to rutting (deformation) and/or improved storage stability.

The invention concerns dry particulate compositions for forming a geopolymer, comprising an aluminosilicate containing mineral, a polymeric additive, an alkali metal silicate, and an alkali metal hydroxide. The invention concerns processes of making geopolymers, the geopolymers, as well as the use of the dry particulate compositions in the formation of geopolymers.

Suspensions of elastomer particles for cement compositions and associated methods of cementing. An example method includes providing a suspension of elastomer particles. The suspension of elastomer particles includes elastomer particles, an aqueous fluid, a viscosifier, a surfactant, and a clay-based stabilizer. The suspension may be combined with a cement slurry to form a cement composition. The cement slurry includes a cement and a base fluid. The cement composition may be introduced into a wellbore penetrating a subterranean formation. The cement composition may be allowed to set in the wellbore.
