Abstract

The objective of this research is to study in laboratoryпїЅs materials such as: cationic bituminous emulsions, aggregates, fly ash, etc., in order to develop optimal and appropriate mix formula for "cold" waste asphalt recycling with the addition of slow breaking cationic bituminous emulsions, fly ash, cement and natural aggregates. The purpose of this approach is to obtain an "optimal combination" comprising the above-mentioned materials as well as the mixing of the wear layer on the surface of the road on which the recycling operation is intended. The idea of "optimum combination" means the full use of pre-existing material and new additions of minimal amounts, thus reducing costs and encouraging the idea of "reusing" old, but recyclable materials. The use of recyclable materials in construction is not just a gesture of solidarity with nature, but also a clever tactic that results in increased reuse potential. Cold recycling consists in the complete use of the resulting material by milling, degraded bituminous pavement in the addition of natural binders and aggregates and putting it into operation by means of a recycling machine. Materials used: natural aggregates added to those resulting from road dressing, bitumen emulsion, fly ash, cement.
