PASS can be utilized for a variety of road maintenance needs. PASS emulsion is a polymer modified asphalt-rejuvenating agent. It has enhanced low and high temperature properties and resists low temperature cracking; as well as maintains and restores asphalt pavements without tracking or bleeding. PASS restorative seals may be applied at ambient temperatures ranging from 45°F to 120°F.

SUBJECT:    Letter of Recommendation

I am pleased to recommend the PASS Scrub Seal product used on the City of Santa Maria Street Maintenance (Chip Seal) Project Bid 05/14 for the Award of Excellence nomination.

The City of Santa Maria has recently completed our annual street maintenance program for 2005. The project included over 500 tons of PASS CR Asphaltic Emulsion, and over 35 tons of PASS QB Surface Sealer. These products allowed application of the chip seal and fog seal maintenance strategies to over 450,000 SY of city streets over a period of two weeks. Ambient temperatures and weather conditions did not affect the performance of the products. Crews were able to begin application work early in the morning and continue until late in the afternoon, thereby maximizing daily production and minimizing the overall duration of the project and traffic control impacts to the public. Also, the product increased the flexibility of the construction process so that schedule recovery necessary to overcome unforeseen delivery difficulties and site conditions did not impact the overall project schedule and project goals.

Another beneficial aspect of the product is the increased chip retention. This product characteristic reduced impacts to the public due to chip displacement onto sidewalks and driveways. The City experienced fewer customer complaints due to these problems than in past chip seal projects.

Furthermore, we hope to realize the benefits of roadway crack filling from the PASS CR product by eliminating our current process of crack sealing. The City Streets Division will be able to experiment with this possibility in the near future, and we are very excited about the prospects of the reduced costs and dedication of limited staff resources from this benefit.

If you have questions regarding this matter, please call me at (805) 925-0951 x225.
