The disclosure discloses a high-viscosity, high-elasticity, and anti-aging composite modified asphalt and a preparation method thereof, solves the technical problem that the comprehensive performance of an existing asphalt ultrathin wearing layer needs to be further improved so as to prolong the service life of a pavement surface layer and reduce the pavement maintenance costs. The composite modified asphalt is prepared from the following components in parts by mass: 100 parts of a matrix asphalt, 10 to 15 parts of a thermoplastic styrene-butadiene rubber, 5 to 8 parts of a tackifier, 0.5 to 1.5 parts of a plasticizer, 2 to 5 parts of a compatilizer, 0.1 to 0.4 parts of a stabilizer, and 0.01 to 0.05 parts of an anti-aging agent. The composite modified asphalt prepared by the disclosure has the advantages of high elasticity, high viscosity, excellent aging resistance, etc.

A sulfur-extended plastomer asphalt binder composition useful for water proofing, damp proofing and roofing applications includes elemental sulfur, a plastomer and an asphalt binder. The sulfur-extended plastomer asphalt binder composition can be applied to the surface of a protected member such that the sulfur-extended plastomer asphalt binder composition contacts, adheres to and forms a layer upon the surface of the protected member. The asphalt binder composition is applied at a temperature no greater than 150 C.

Stabilized volatile briquettes and processes and apparatuses for making and using the same are provided. The stabilized volatile briquette includes a volatile material and a thermoplastic binder material such that the thermoplastic binder material binds the volatile material together to define a briquette that is stable. The process includes mixing a volatile waste material and a thermoplastic binder material to form a briquette mixture, shearing the briquette mixture, extruding the briquette mixture to form a thermoplastic briquette extrusion, and hardening the thermoplastic briquette extrusion to form a stabilized volatile briquette. The apparatus includes an extruder, a heating portion operably connected to the extruder, and a heated die operably connected to the heating portion such that the extruder, the heating portion, and the heated die are configured to gradually heat a thermoplastic binder material such that the thermoplastic binder material binds a provided volatile material together.

A binder composition for asphalt pavements that includes: an asphalt binder; an elastomeric polymer; a wax modifier; and optionally at least one of: i) fumed silica or fumed alumina; and ii) a saponified fatty acid and a resin acid gelling compound. The composition is applied as a tack coat and/or a stress absorbing membrane interlayer and is non-tracking.

A modified asphalt composition comprises or is produced from asphalt and phosphorous acid. The composition optionally further comprises one or more of an ethylene copolymer that comprises copolymerized units derived from ethylene and an epoxy-containing comonomer and a nonreactive polymer such as a styrene/conjugated-diene block copolymer. Further provided are processes for producing the composition in addition to products such as paving materials and roofing materials that comprise the compositions.

The present disclosure relates to a sulphur additive to suppress hydrogen sulphide emissions from Sulphur Extended Asphalt. The sulphur additive of the present disclosure comprises 5 sulphur in an amount ranging from 80 to 98 wt % and at least one aluminosilicate in an amount ranging from 2 to 20 wt %. The sulphur additive of the present disclosure suppresses the H2S emission up to acceptable safe limit during the preparation and application of the sulphur extended asphalt at elevated temperature.
