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 pothole patcher vehicle is configured to discharge a calibrated flow of a patching material. The pothole patcher vehicle broadly includes a material conveying device and a processor. The material conveying device includes a motor and is configured to supply patching material to a discharge spout. The processor is operably coupled to the material conveying device.

Methods for sealing cracks and expansion joints comprising the use of an adhesion promoter. In certain embodiments, the adhesion promoter comprises a vinyl polymer.

Asphalt paving system and method involves the use of a primer, comprising hydrophobic microwave absorbing material mixed in a hydrophobic liquid, between an asphalt layer and a base layer below. The primer is configured to be deposited on the base layer at room temperature without preheating. Heating the hydrophobic microwave absorbing material, sandwiched between the asphalt and base layers, by microwave energy, allows for both effective de-icing of the asphalt pavement and for efficient repairs of the pavement, the latter by striping of the asphalt layer from the base layer.

The present disclosure provides various aspects for mobile and automated processing utilizing additive manufacturing and the methods for their utilization. In some examples, the mobile additive manufacturing apparatus may perform surface treatments that support the building of walls. Other examples may involve the support of creating and repairing advanced roadways.

A method of treating particulate, in substance including selecting a load based on a planned in use loading of the particulate; applying the load to the particulate; injecting material below the load; and removing the load.

The invention relates to a structure for the reinforcement of pavements. The structure is provided at predetermined positions with interruptions or with weakened zones. The invention further relates to a method of manufacturing such a structure and to a method of breaking up a pavement reinforced with such a structure.

A portable dispensing device for dispensing a crack sealant, comprises an outer housing, a melting kettle for holding crack sealant to be melted, a guide mechanism in the housing below the kettle for positioning a burner below the kettle, a burner assembly removably mounted in an air gap between the outer housing and the melting kettle using the guide mechanism, the removable burner assembly configured to direct a flame against a surface of the melting kettle, a control valve fluidly connected to the melting kettle to dispense melted crack sealant, and a handle assembly for manually moving the portable dispensing device.

The invention relates to a planning system and method for operating one or more road milling machines. In that context, material properties of a road are captured and are geographically associated with one or more roads or road segments. Based on the material properties, an expected milling output of a road milling machine is ascertained, in the context of carrying out milling tasks on the road, or an expected wear on the milling tools. An optimized sequence of milling tasks to be carried out is created on the basis of those data. Accordingly, the invention may enable optimized deployment of the one or more road milling machines and of resources necessary for carrying out the road milling tasks. Aspects of the planning system may be remotely implemented for centralized application with respect to each of the road milling machines, or locally implemented for individual road milling machines.

A lifting system for a concrete component comprises a void former incorporated into the component during casting and which provides within the component a void which receives a locking pin of a lifting anchor assembly which is locked within the void by rotation of a locking pin. The lifting anchor assembly has a visual indicator to indicate when the pin is in its locked condition within the void, and a pivotal lifting shackle of the assembly is prevented from movement into a position in which lifting can take place until the pin is in its locked condition. Preferably a base of the void former is configured to retain components of a jacking system by which a concrete slab used for road repair can be jacked into a level configuration with the remainder of the roadway when it has been positioned by use of the lifting system.
