A soil compactor for compacting soil material, in particular asphalt, comprises at least one compactor roller (14, 16) which is rotatable on a compactor structure (30) around a roller axis of rotation (W) which is essentially orthogonal to a compactor longitudinal direction (L) and at least one marking unit (26, 26) carried on the compactor structure (30) for applying marking material (M) to soil material (12) driven over by the soil compactor (10).

Arrangements for diverting and removing spoil created when a microtrench is being cut. The disclosed arrangements divert the debris and dust away from the microtrench during the cutting process. In optional embodiments, a spoil vacuum system is used to remove the dust particles during the debris diversion process. In further optional embodiments, a microtrench slot cleaning tool and slot vacuum system may be used. The microtrencher can be mounted on a skid-steer loader or a similar support vehicle.

A method of repairing an edge guard for a road milling machine. An edge guard includes an edge portion having a plurality of insertion receptacles receiving insertion projections of a plurality of runner segments. A worn runner segment is removed by withdrawing its insertion projection from it associated insertion receptacle. A new runner segment is replaced by inserting its insertion projection into the insertion receptacle from which the worn runner segment was taken.

A marking device that includes a base; at least two telescoping legs movably coupled to the base; and an indicator, the indication being attached to a top portion of an uppermost leg of the at least two telescoping legs, the marking device including: (1) a retracted position wherein the at least two telescoping legs are seated within the base and (2) an extended position wherein the at least two telescoping legs are telescoped outwards from the base and locked in the extended position.

An expansion joint design for supporting transfer loads. The system includes an elongated core and at least one longitudinal load-transfer member which are bonded together.

Provided herein is an asphalt membrane emulsion for reducing voids in an asphalt joint that includes asphalt, an asphalt modifier, mineral filler, an emulsifier, and water. Provided herein is a method of making an asphalt membrane emulsion, the method including: forming a first phase; forming a second phase; pumping the first phase and the second phase into a colloid mill; and mixing the first phase and second phase into the colloid mill to form the asphalt membrane emulsion. The first phase includes asphalt, asphalt modifier, and mineral filler. The second phase includes water and an emulsifier. A method of applying an asphalt membrane emulsion to fill a crack is also provided.

A device for applying a distribution cabling tape system includes a distribution cabling tape having an adhesive capable of adhering to a concrete or asphalt substrate and a distribution cable. The device includes an endoscope camera, wherein movement of the device in one direction simultaneously applies both the distribution cable and the distribution cabling tape at a location on the substrate viewable by the endoscope camera. A method for registering a cable and a cabling tape into a channel in a concrete or asphalt substrate includes using an endoscope to view the location at which the cable and cabling tape are applied.
