A portable device for transporting asphalt repair materials for use in repairing potholes in asphalt pavements. The device has a body with a hopper compartment for transporting and dispensing asphalt mix materials. Emulsion oils are held and dispensed from a separate emulsion oil tank. An emulsion pump provides emulsion oils to a spray wand. The emulsion oil tank includes an emulsion rejuvenator apparatus which works to prevent separation of the emulsion oils. A control circuit actuates the rejuvenator any time that the emulsion pump is turned on to supply emulsion oils to a spray wand to spray emulsions onto the road repair site.

The present invention provides a functionally dry warm mix asphalt binder composition modified with lubricating agents or additives that can be mixed with aggregate and compacted at temperatures substantially below asphalt binder compositions that do not contain the disclosed lubricating additives.

A vehicle for distributing a fluid or a solid material on or into the ground has one or more axles for supporting the vehicle on the ground, a vessel for holding the material to be spread on or into the ground, and a plurality of valves for controlling the lateral extent of distribution of the material on or into the ground. The vehicle may have a plurality of control switches for controlling the lateral extent of distribution of material and operative to control the opening and closing of different valves or different groups of valves of the plurality of valves. The vehicle may have an indicator for each valve or group of valves, the indicator operative to provide different indications for a plurality of different statuses for the corresponding valve or valves.

Cold-in-place asphalt recycling is disclosed. A foamed asphalt may be produced by injecting water and optionally compressed air into a hot asphalt stream. A lubricating surfactant may be added to the hot asphalt stream to improve performance. The foamed asphalt may be mixed with reclaimed material to provide a uniformly coated paving material that can compacted to a desired density.

A continuous asphalt mix system for using a microwave heating vessel at the point of production that includes a microwave energy suppression tunnel with one or more mesh flaps for substantially reducing or preventing the leakage of microwave energy from a microwave system, while having a continuous flow of product through the vessel and suppression tunnels. The suppression tunnels are installed on the inlet and/or the outlet side of the system and are sized to suppress leakage.
