ELOT TS 1501-05-03-16-00 Full depth road pavement reclamation with cold in-place (CIR) recycling and addition of foamed asphalt

The works specified in this document relate to the reclamation of asphalt layers and part of the unbound or processed aggregates in the existing road pavement using cold in-place recycling (CIR) with or without the addition of aggregates and the addition of foamed asphalt as a binding material. The addition of asphalt to the mix increases cohesion, and improves flexural strength and tolerance to humidity. The reclaimed layer forms the stabilised base for the road pavement which is being replaced. Cold in-place recycling is a technique for replacing road pavements in which existing materials in the road pavement are re-used at ambient temperatures without applying heat.

Reclamation is used after systematic investigation and sampling of the existing road pavement, a study of the composition of the mixed to be laid, and determination of the minimum layer thickness (road pavement dimensioning).

The works include:

• Crushing, recycling and homogenising the aggregates mix from the top layers of the existing road pavement.

• Improving the granulation of the materials to be reclaimed by adding suitable aggregates, when necessary (see paragraph 4.2 hereof).

• Adding and mixing in suitable additives such as cement, foamed asphalt (asphalt bulked up with water), and potentially other chemical additives based on the approved composition design.

• Laying and compacting the resulting mix to create the new road pavement base.
