  • METHOD OF FORMING A MULTI-COURSE PAVER FOR PAVING MULTI-COURSE ROAD SURFACES, AND MULTI-COURSE PAVER
    Publication number: 20080063475
    Abstract: A method to form a multi-course paver from two independent pavers, namely a lower base paver (10) and an upper paver (11) saddled thereon using the piggyback principle. Both the base paver (10) and the upper paver (11) can be used as stand-alone pavers for producing single-layer road surfaces. Therefore, the invention does not require any costly add-on devices, which can be used only for multi-course paving, for paving the second course of the road surface.
