Larry Scofield, Director, Pavement Innovation-American Concrete Pavement Association (ACPA)/International Grooving and Grinding Association (IGGA), said that by a virtual meeting, the SPS-2* pavement preservation pooled fund group will review the most recent products of the pooled fund contractor and NCE (originally Nichols Consulting Engineers, Chtd. (1990)—a client-focused consulting engineering, planning, environmental, and construction services firm that specializes in the innovative design and construction of infrastructure).
Some of the products to be reviewed and discussed include the following:
- Evaluating the Impact of Initial Pavement Smoothness on Pavement Performance
- Evaluating the Impact of Pavement Design Features on Pavement Performance
- Evaluating the Impact of Joint Score on Pavement Performance
- Evaluating the Change in Localized Roughness (ALR) Over Time and the Corresponding Distress Manifestation
- Impact of Shoulder Type on Pavement Performance
- Impact of Design Features on Load Transfer Efficiency
- Joint Seal Failure Analysis
The SPS-2 preservation pooled fund, TPF 5 (Transportation Pooled Fund 5), consists of seven states:
- Washington State DOT as the Lead State
- Arizona
- California
- Colorado
- Georgia
- Kansas
- North Carolina
Of special note is that the Georgia DOT participated in the pooled fund and does not have an SPS-2 project, but they recognized the value of the findings to the concrete industry.
Previous products of the pooled fund have been a comparison of SPS-2 actual performance to that predicted by PavementME, a review of the condition of the remaining test sections, and potential future preservation activities.
