A binder composition includes an oligomerized biorenewable oil that is at least 10 wt % of the binder composition. The binder composition also includes an Asphaltene Additive comprising at least 20 wt % to 100 wt % asphaltenes, wherein the Asphaltene Additive is at least 8 wt % of the binder composition.

Provided are a method for preparing a gel composite material with a piezoelectric property, and the gel composite material and use thereof, which belongs to the field of intelligent road traffic. In the method, titanium-containing blast furnace slag and metal oxides (PbO and ZrO.sub.2) are sufficiently and uniformly mixed, an obtained mixture is calcined under a certain thermal system, on the theoretical basis of mineral-phase reconstruction-synergistic regulation of all valuable components, and the mixture is cooled to a room temperature with a furnace to obtain the gel composite material with a piezoelectric property.

Described is a method of manufacturing a binder and the use of the binder to manufacture a roading mixture through mixing with aggregate, or a composite plastic product through the mixture of binder with particulate matter and/or fibre. The binder comprises mixing a plastic with two or more ethylenically unsaturated monomers in a mixing tank. The two or more ethylenically unsaturated monomers may have different homopolymer glass transition temperatures (TO wherein a first monomer structural unit has a homopolymer T.sub.g of greater than 80° C. and a second monomer having a homopolymer T.sub.g of less than 80° C. The plastic may be selected from a plastic comprising a styrene homopolymer, a styrene copolymer, a copolymer of an alkene and vinyl acetate, acrylic polymer and nylon based polymers or co-polymers, polyester-based thermoplastic polymer resin, propylene-based thermoplastic polymer and homo-polymer of an alkene or combination thereof.

Provided is a cover for asphalt including an asphalt emulsion and a method of paving asphalt using the same, and specifically, to a cover for asphalt, which may facilitate adhesion between an existing asphalt pavement layer and a new asphalt pavement layer and substitute for a tack coat. The cover for asphalt prevents an asphalt emulsion from being damaged by heavy vehicles or construction equipment moving for application of a new pavement layer, and allows omitting separate asphalt emulsion application and curing processes before application of the new asphalt layer.

The invention relates to a product and method for repair of roadway or pavement damage such as potholes, concrete/asphalt joints, and other damage to paved surfaces. The product can be adjusted in terms of the cure time of the product, allowing the user to customize the product for best use in the particular repair being made. Fast cures can be obtained of 5 minutes or less, suitable for quick repair of a small defect in pavement, or the cure time can be extended to 60 or more minutes, suitable for larger projects that can take many hours to complete. The product, when mixed, handles like easily pourable concrete mix, but acts like a hot mix repair when cured.

A method and system for generating a rapid digestion process (“RDP”) product are described. The method includes receiving a bitumen compound and first heating the bitumen compound to 320° F. to 420° F. The method then proceeds to add tire rubber to the bitumen compound. The bitumen compound and the tire rubber are mixed for 5 minutes to 360 minutes during a second heating to 525° F. to 700° F. Further, sulfur is added to the mixture of tire rubber and bitumen compound. These steps generate the RDP product. The RDP product is then cooled for transfer to a storage vessel.

Embodiments of a dry mix for producing a concrete composition are provided. The dry mix includes aggregate, cement, and bed ash. The bed ash contains the combustion product of a fluidized bed coal combustion reaction. Additionally, embodiments of a method of preparing the dry mix and embodiments of a method of preparing a concrete composition are provided. The dry mix is also suitable for repairing soil slips, and embodiments of a method of repairing a soil slip are also provided.

Pavement aging can be reduced by applying to an asphalt-containing pavement a topcoat layer or a surface treatment containing asphalt binder with sterols.

A preparation method of a plant-mixed warm regenerated asphalt mixture, comprises the following steps: preparing a RAP material, a new aggregate, a mineral powder, a new asphalt and a regenerant with a total mass percentage of 100%; heating and stirring the RAP material, adding the regenerant, and continuing to heat and stir; placing the product in a development bin for development, wherein a development temperature is 40° C. to 150° C., and a development time is 0.5 h to 6 h; mixing, heating and stirring a product with the new aggregate; and after mixing and heating the product with the new asphalt, adding the mineral powder, and stirring to mold. Addition of the regenerated asphalt mixture in the development process improves the regeneration effect of the old asphalt, and pavement performances of the formed regenerated asphalt mixture can fully reach that of a hot-mixed asphalt mixture produced entirely with new materials.

Efflorescence resistance of concrete blocks is enhanced through the use of glass powder in the concrete composition. The glass powder permits a reduction in the cement content; the glass powder also creates a pozzolanic reaction to change the free calcium ions in calcium hydroxide to calcium silicate to fix the calcium ions inside concrete. The composition includes cementitious binding material of ordinary Portland cement, fly ash, calcium sulfoaluminate cement, ground-granulated blast-furnace slag in an amount from 20 to 25 wt. %. Coarse aggregate is provided from 10 to 15 wt. percent. Fine aggregate is from 32 to 39 wt. %. The composition further includes glass powder having a diameter of less than approximately 75 microns in an amount from 17 to 23 wt. %. Water is present in an amount from 6 to 9 wt. %. The dry density of formed paving blocks is 1800-2200 kg/m.sup.3.
