Annapolis, MD - The International Slurry Surfacing Association (ISSA) is partnering with the Asphalt Institute to offer a second series of 90-minute webinars designed to educate public agencies about different pavement preservation topics. The webinars will take place the first three Thursdays in November and discuss the following topics:
- November 3, 2011: "Mix Design Methods for Emulsified Asphalt Slurry Seal, Micro Surfacing and Chip Sealing"
- November 10, 2011: "Combining Preservation Treatments"
- November 17, 2011: "ISSA Inspector's Manual"
"Mix Design Methods for Emulsified Asphalt Slurry Seal, Micro Surfacing and Chip Sealing" will illustrate the mix design process for each treatment and discuss component material analysis, proportion optimization, performance testing, final formulation adjustments and recommendations. The webinar will also address mix design requirements and standard methods, the importance of specified tolerances and proportioning according to the job mix formula in the lab and in the field, as well as how failure to adhere to mix design proportions can cause performance issues.
"Combining Preservation Treatments" will discuss the benefits of several different combination preservation treatments that are now being widely used, including cape seal, stress absorbing membrane interlayer, fog seal over chip seal and surface treatments over crack treatments. These tailored combination treatments provide a durable final surface and are a very cost-effective approach to improving the pavement condition. The webinar will identify combination treatments, their appropriate application and special considerations for the combination of treatments.
"ISSA Inspector's Manual" will address the highlights of the new ISSA Inspector's Manual by guiding participants through all phases of slurry and micro surfacing construction and inspection. This webinar will also cover slurry systems, material and design, the construction of each treatment, calibration procedures and contract administration. It is not necessary to have the ISSA Inspector's Manual during this webinar to follow the presentation and benefit from the information discussed. Purchasing the manual either before or after the webinar is highly encouraged to ensure you have a valuable reference manual for determining pavement preservation quality.
