The Oregon Association of County Engineers and Surveyors is providing a chip seal workshop for agencies responsible for road maintenance in Oregon and Washington. This is a continuation of the OACES series of workshops previously hosted by Marion County in 2011, 2013, and 2016.
Materials from previous Chip Seal Workshops can be found here.
These workshops provide a forum for peer presentations to discuss different agency approaches to chip seals. They allow agencies to share what’s working and what’s not working in their pavement management programs, to share ideas, and to provide technical education.
The next Chip Seal Workshop is now full. A waiting list has been established.
Contact Kevin Hamilton to put your name on the waiting list for this event.

The morning sessions will be presentations from several vendors and will include a wide range of information and experience levels. Each presentation is intended to dovetail on the previous one and will cover information from the basics of asphalt emulsions to a more in depth examination of composition and specifications.
Vendors, presentations and topics include:
Capital Assets & Pavement Services. Provide a discussion about understanding Pavement Condition Indices (PCIs); how they’re assessed and how they can be used in assessing the management of a pavement maintenance program. This will include a review of PCIs across the state, and observed trends.
Joel Conder
Albina Asphalt. Review of the ABC’s of the alphabet soup that is asphalt emulsions. This will include an explanation of the different types of asphalt emulsion products available (high float, CRS, CQS, CSS, PMRE, etc.); a discussion of cationic vs. anionic; and a little bit about how the emulsions are made.
Keven Heitschmidt
Idaho Asphalt/Western Emulsions. How asphalt emulsions are made, with an in depth discussion of the different components that comprise an asphalt emulsion. This will include a discussion of what these components do for the emulsion; and how their presence, absence, or different concentrations or characteristics will affect the performance of the product.
Doug Olsen
Blueline Transportation. A discussion of the specifications that agencies use when ordering material. This is intended to teach people to understand what the different specifications mean, and how changing the parameters of those specifications can be expected to create different performance characteristics in the final product.
Troy Tindall
Knife River. Provide a discussion about oil rock. This will focus on production considerations. This presentation is intended to discuss how a slight change in a spec (e.g. 3/8-10” vs. 3/8”-4) can mean a difference of price, or even a lack of desire to produce the product depending on quantity. This will also include a discussion on balancing orders. That is, understanding how production of one product can be cheaper if it’s balanced with the production of another product to minimize waste.
The afternoon will include Peer presentations from counties and agencies on their practices and processes. In addition to peer presentations, each of the three asphalt emulsion vendors will discuss some of their products. This may include new products that are being introduced into the marketplace; and/or existing products that may be under-utilized in our area but may offer a benefit to agencies. The goal of these afternoon vendor presentations is to present new tools for agencies to consider adding to their tool box.
