This product results from the combination of bitumen in petroleum-derived solvents of adequate volatility. It must comply with specific characteristics: homogeneous appearance, practically free of water and no signs of coagulation Por seu lado, On the other hand, solvents work solely as a vehicle for using bitumen in paving services. Solvent evaporation is called “diluted asphalt cure” and can be fast, medium or slow.
If diluted, it leaves the bitumen as a residue, developing the necessary binding properties.
After the asphalt application, when the total evaporation of the solvent occurs, the agglomerating properties are guaranteed – necessary for its application.
