Modified nonvolatile cold asphalt binder and recycled asphalt mixture using thereof

A nonvolatile cold modified asphalt binder and a nonvolatile cold recycled asphalt mixture using the same are manufactured by optimally mixing a petroleum asphalt, a native asphalt, a polymer modifier, process oil, and an adhesive strength enhancer. The nonvolatile cold modified asphalt binder includes at least one petroleum asphalt selected from a straight asphalt or a blown asphalt; at least one native asphalt selected from gilsonite, glance pitch, and grahamite; a rubber-modified-compound (RMC) polymer modifier which is a vinyl aromatic hydrocarbon-conjugated diene block copolymer including at least one of a styrene-butadiene block copolymer (SBS), a styrene-isoprene block copolymer (SIS), and a styrene-ethylene-butylene block copolymer (SEBS); at least one process oil selected from paraffin oil, naphthenic oil, aromatic oil, natural oil, and mineral oil; and at least one adhesive strength enhancer selected from rosin esters, modified acryls, modified silicones, polyvinyl esters, and silicone resins.

PROCESSES FOR MAKING A SUPER-INSULATING CORE MATERIAL FOR A VACUUM INSULATED STRUCTURE
20200318776 · 2020-10-08 · ·

A method for forming a super-insulating material for a vacuum insulated structure includes disposing glass spheres within a rotating drum. A plurality of interstitial spaces are defined between the glass spheres. A binder material is disposed within the rotating drum. The glass spheres and the at least one binder material are rotated within the rotating drum, wherein the binder material is mixed during a first mixing stage with the glass spheres. A first insulating material is disposed within the rotating drum. The binder material, the first insulating material and the glass spheres are mixed to define an insulating base. A second insulating material is disposed within the rotating drum. The secondary insulating material is mixed with the insulating base to define a homogenous form of the super-insulating material, wherein the first and second insulating materials occupy substantially all of the interstitial spaces.

COATED-FINE-AGGREGATE, CONCRETE COMPOSITION AND METHOD
20200299192 · 2020-09-24 ·

A concrete composition and method include a portion of fine aggregate bearing a coating of a polymer or an admixture, which may be a continuous coating layer or a layer of powdered, discrete particles embedded in a binder. The polymeric coating may be an admixture in powdered form, a super absorbent polymer (insoluble in water, but absorbing water), or another polymer such as the acrylamides, co-polymers thereof, polyacrylamides, or the like (soluble in water). The coating absorbs water, but particles are too small to form significant voids. Water is absorbed into the concrete mix in far greater proportions (e.g. w/c ratio over 0.5) improving workability, doubling workability time, and improving ultimate compressive stress (strength).
