Abstract
The invention relates to an optional additional process during routine rehabilitation or recycling of road surfaces.

An apparatus for converting a paver to an in-situ road-recycling device, the apparatus having a frame mountable onto the front of the paver, comprising:
- (i) means for lifting and delivering loosened material from a road or a pavement surface to a reservoir on the paver device to expose road base or road subgrade surface;
- (ii) optional means for treating the loosened material with at least one fluid and/or at least one stabilizing additive;
- (iii) at least on height adjustable wheel or roller provided on the frame to assist in the lift depth adjustment of the apparatus in order to reach a predetermined lift depth of loosened material;
- (iv) optional means for laying a geomaterial onto exposed road base or road subgrade surface;
- wherein the material is re-laid onto the road base or the road subgrade by the paver in a predetermined profile in a single pass.
