TEST & EVALUATION REPORT

Screening Evaluation of Shingle Rejuvenator

 


BACKGROUND:

Rejuvenator has a long history of limited use in the asphalt roofing industry. Initial use was limited to conventional
hot-mopped built-up-roofs. Over the years, there have been attempts to restore/maintain rejuvenated asphalt
shingle roofs.
In the most recent times, asphalt rejuvenation has gained national focus in the paving industry. In response to the
enhanced focus, a number of new technologies have been introduced. Some of these products are advancing the
rejuvenation/restoration technologies and are hypothesized to exhibit efficacy in the asphalt roofing industry.


OBJECTIVE:


Perform and assess selected screening evaluation to provide insight on Bio-Based Roof Shingle
Treatment System.


CONCLUSIONS:


Based on a Spray Application Rate of 1 gal/125 ft.2, followed by a five (5) day ‘cure’ _period on aged shingles provided. 1. Flexibility23°C was improved (from a Failure to pass). 2. Granular Adhesion was improved significantly from a granular loss of 1.11 g to a loss after treatment of 0.15 g, an 86% improvement.
3. Hail Impact was slightly improved after treatment. The improvement 6.6%, was minimized by the type of shingle evaluated – organic felt based. The data suggests Hail Impact would have a greater improvement on FG mat-based shingles. 4. Fire Resistance ‘UL Speed of Flame:’ The treated shingles exhibited a flame spread of 86 in2 vs. the untreated shingles exhibiting a 144 in2 spread. 60% better than the untreated shingles, this was unexpected.

The testing below is virtually the same product that has been used to rejuvenate asphalt roads and parking lots for over 14 years, we just adapted it for asphalt shingle rejuvenation.


Asphalt Rejuvenator
Product Description
An asphalt pavement fog seal rejuvenator application that brings oils to aid in an asphalt pavements flexibility and leave a seal from further oxidation with a polymer coating. We have laboratory testing showing these benefits through a five year ageing simulation.
