AMIGUARD™ Rapid Penetrating Emulsion Rejuvenator: An Early-Life Preservation Solution

Asphalt pavements begin aging immediately after construction. Both physical and chemical changes to the pavement occur as a result of oxidation, UV exposure, presence of moisture, freeze and thaw cycles, and traffic wear. Early life aging can quickly lead to severe functional distresses such as raveling and cracking and set the stage for more costly downstream structural repairs. Early-life preservation treatments are critical to extending maintenance timelines and lowering life cycle costs of asphalt pavements.
