CHEM-CRETE ASP®

CHEM-CRETE ASP^® is a silicone-modified asphalt pavements sealer. It is engineered using a special blend of oxidized asphalt binder that is UV stable and very rich in its aromatic compounds and modified with several moisture-insensitive silicone-based compounds that have multifunctional active groups.

ASP provides the surface of treated asphalt pavements with an excellent water-repelling property due to the presence of the silicon compounds. ASP features a low viscosity and low surface tension compared to conventional asphalt cutbacks and emulsions giving ASP the characteristics of high penetrability.

Such properties allow it to flow easily through voids and capillaries making it an internal treatment rather than just a surface treatment for asphalt pavements where:

• It compensates for the aromatic compounds that might have been lost during the curing process and due to the oxidation reaction and UV attack.
• The active silicone compounds in ASP minimize the losses of the aromatics in the pavement and minimizes oxidation, and thus expected to increase the service life of the pavement by two folds.
• It enhances the adhesion property and bonding strength between the pavement elements especially with the aggregates, thus dramatically reduces displacement and detachment as well as spontaneous emulsification due to moisture presence.
• It reduces the porosity of the pavement by sealing tiny voids from the surface side.
