A paving mixture for application to a surface and a method for the same are provided. The mixture comprises a binding material layer applied to the surface to form a base layer on the surface, and an aggregate material layer applied on top of the binding material layer, wherein the binding material layer comprises at least 13% of the bitumen in the paving mixture by weight, the aggregate material layer contains an asphalt mixture that provides a road surface, and the aggregate material layer and the binding material layer are combined on the surface within 30 seconds of application of the binding material layer.

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

Described herein is a process for paving a surface with an asphalt paving material, comprising the steps of laying asphalt paving material on a surface to be paved; and combining an asphalt rejuvenator and the asphalt paving material; wherein the asphalt rejuvenator and the asphalt paving material are combined immediately before, concurrently with, or immediately after the asphalt paving material is laid on the surface to be paved. The asphalt paving material may be virgin asphalt, or it may comprise reclaimed asphalt pavement and/or recycled asphalt shingles.

An electronic device includes a first image sensor, a second image sensor, one or more image processing modules, and a display. The first image sensor generates first image data. The second image sensor generates second image data. The one or more image processing modules process one or more image data among the first image and the second image data. The display displays the one or more image data among the first image data or second image data processed by the one or more image processing modules. The thumbnail generation module generates thumbnail data using the one or more image data among the first image data and second image data processed by the one or more image processing modules. A method includes converting the plurality of image data into a format displayable on a display, and generating thumbnail data using the image data of the displayable format.

A decontaminating pavement which can be applied as a flooring for playgrounds or similar surfaces, and includes at least one base made of black rubber that is ground and glued with a resin binder; and one upper layer of encapsulated and colored rubber, with resins, pigments, additives, and catalysts, wherein the surface of said upper layer is impregnated with a transparent film containing a photocatalytic additive which, in the presence of photons originating from sunlight or from a UV lamp, produces a NOx gas or particle decontamination or elimination effect. The photocatalytic additive forming the transparent film with which the surface layer is impregnated can be based on nano titanium. The upper layer of encapsulated rubber can include, as catalysts, an enhancer of the catalytic and aromatic/aliphatic binding effect which enhances and activates the effect of the photocatalytic additive of the film impregnating the surface of said upper layer.

A method for repairing/treating a pavement with the use of a rheology modifier is disclosed. The method comprises first applying a layer of a rheology modifier composition comprising a rejuvenating component onto the top surface of the pavement that needs repair, then applying a second layer of a binder onto the rheology modifier layer. The second layer of binder effectively seals the rheology modifier layer with the rejuvenating component for intimate contact with the top pavement surface, thus penetrating the surface layer to extend the life of the pavement surface, arresting the deterioration of visco-elastic properties and restoring some of those properties.

Among other things, techniques are described for steering angle calibration. An autonomous vehicle receives a steering angle measurement and a yaw rate measurement, and estimates a steering angle offset using the steering angle measurement, the yaw rate measurement, and a wheel base of the autonomous vehicle. An estimated yaw rate is determined based on a yaw rate model, the steering angle measurement and the estimated steering angle offset. The yaw rate measurement and the estimated yaw rate are compared and an action is initiated on the autonomous vehicle in response to the comparing.

Methods for repair of cracks and niches in concrete using carbonic anhydrase embedded in a gelatin, hydrogel, or other aqueous matrix are provided. A durable corrosion resistant concrete mix containing carbonic anhydrase is provided, as are methods of making and using the durable corrosion resistant concrete. Corrosion resistance and durability derive from decreased porosity compared to concrete without the enzyme, conferring decreased access of deleterious materials such as chloride ions to interior portions of the concrete.
