The Environmentally Friendly Rejuvenator. Ideal for newer roads, streets, shopping centres, airports, and highway shoulders. AsPen® is an emulsion based pavement surface treatment that replenishes the binder that is lost through oxidation, weathering, and aging. AsPen® is bitumen emulsion based (AsPen® AC)
AsPen® Advantages: * Deep black colour provides like-new appearance. * Helps melt snow and ice faster. * Environmentally friendly water based formula. * One coat application.
Aspen® Sealer/Rejuvenator Penetrates, Seals and Protects Asphalt Pavement
What is AsPen®?
AsPen® replaces and protects the binder lost through the damaging effects from oxidation from the sun. AsPen® is chemicaliy engineered to reverse the effects of aging and to seal the pavement and help prevent raveling prolonging the service life of the pavement substantially.
What is AsPen® AC?
AsPen® AC is a specially modified bitumen base emulsion formulated from similar bitumens used to make hotmix pavements.
What Is AsPen® RT?
How does AsPen® work?
For all of its outstanding qualities as a paving material, hotmix alone is no more impervious to the effects of time, weathering and tough service than any other construction material. With the passage of time, the need for maintenance becomes signaled by dryness, brittleness and other visible signs of deterioration, such as loss of matrix, raveling, cracking and spalling.
AsPen® is excellent for its ability to delay the aging process of hotmix from the outset and to reverse any premature aging that might be caused by construction variables such as excess heat at the manufacturing plant, excess voids caused by low temperatures during compaction, critical mix design and other inconsistencies. All of these factors leave the finished surface of hotmix vulnerable to air and water intrusion, chief causes of premature aging.
By replenishing the binder lost through oxidation and weathering, any moderately aged asphalt can be protected, and strengthened as well as renewed to its original colour and look. This can be achieved by spraying AsPen® directly onto the asphalt surface to combine with the existing binder forming a protective surface treatment. Permeability tests confirm that even after several years AsPen® continues to repel air and water.
How Aspen® Works
AsPen® is a specially modified bitumen emulsion designed to rejuvenate and prolong the service life of asphalt pavements. AsPen® replenishes the Asphalt Binder™ that is lost through the oxidation and aging process.
AsPen's exceptional "wicking" properties enable it to penetrate much deeper into the asphalt pavement than unmodified asphalt emulsions. As AsPen® penetrates it seals and waterproofs the pores in the asphalt and dramatically decreases the oxidation process as well as greatly reducing the damaging effects of freeze/thaw cycles.
Uses of AsPen®
AsPen® is designed to both prolong the life of new asphalt pavement as well as to rejuvenate older & oxidised pavement. AsPen® replenishes the bitumen content when performing heat scarification or other surface recycling work.
Does Not Require compaction AsPen® produces a tack-free surface when dry and does not require sanding prior to opening pavement for traffic. The result is added savings and increased safety for vehicle traffic.
Fast Drying AsPen's fast drying action allows pavement to be opened up to traffic soon after application (typically one to two hours after application under ideal weather conditions). This means less down time and greater flexibility in scheduling performance of maintenance work.
Attractive Black Colour AsPen's rich, deep black colour gives oxidised pavement a "like new" appearance which enhances the vibrance of any line markings.
Environmentally Friendly AsPen® is a water-based emulsion containing no hazardous solvents or materials.
