Abstract

A paving convoy for producing a bituminous cover layer including a self-propelled road paver and a paving material feeding assembly which is self-propelled and travels in front of the road paver. A paving material conveying device extends from the feeding assembly to the road paver. A spraying module including its own undercarriage and components for storing and deploying bitumen emulsion is provided between the feeding assembly and the road paver. The spraying module has a spraying bar facing the front end of the road paver. The spraying module is either coupled to the feeder assembly by a detachable towing connection or to the road paver by detachable pulling connection.

Claims

1. Paving convoy for producing a bituminous cover layer, comprising:

self-propelled standard road paver having an undercarriage and at least one paving screed;

paving material feeding assembly which is self-propelled in front of the standard road paver,

paving material conveying device extending from the feeding assembly to the road paver; and

spraying device including components for storing and deploying a bitumen emulsion on a planum between the feeding assembly and the road paver and over the working width of the paving screed, the spraying device having;

a spraying bar arranged below the conveying device and facing the front end of the road paver,

the spraying device being a spraying module having its own undercarriage for travelling on the planum,

the spraying module being structurally separated from the feeding assembly and the road paver; and

one of either a towing connection is provided between the spraying module and the feeding assembly, or a pushing connection is provided between the road paver and the spraying module.

2. Paving convoy according to claim 1, further comprising:

a power transmission connection and/or a control signal transmission connection between the spraying module and either the feeding assembly and/or the road paver.

3. Paving convoy according to claim 1, the road paver has at least one paving screed the working width of which is adjustable in controlled fashion, and further comprising a control device for synchronously adapting the spraying width of the spraying module to the working width of the paving screed, preferably, a common working width control assembly.

4. Paving convoy according to claim 1, the spraying module is arranged below the conveying device, preferably, with a height lower than the cantilevering height of a supporting frame of the conveying device of the feeding assembly.

5. Paving convoy according to claim 1 further comprising at least one spraying bar for deploying bitumen emulsion on the travelling lanes of the road paver is detachably arranged at the road paver behind the undercarriage, the spraying bar being supplied and controlled from the spraying module.

6. Paving convoy according to claim 2 further comprising at least one spraying bar for deploying bitumen emulsion on the traveling lanes of the road paver is detachable arranged at the road behind the undercarriage, the spraying bar being supplied and controlled from the spraying module.
