PoreShield™: 9 Years of Concrete Roadway Protection and Counting
Location: U.S. Hwy 231 in Lafayette, Indiana
Date: Applied in August of 2011
Application Type: Pavement Joint Application – Existing Pavement
Applicators: Indiana Department of Transportation, Purdue University
In August 2011, the Indiana Department of Transportation and Purdue University launched a study to evaluate the effectiveness of a new soy-based concrete protection product that was in development at the university. This was the first of many real-world studies to test this new product called PoreShield. They selected a heavily traveled and heavily deiced section of U.S. Highway 231 in Lafayette, Indiana with 13-year-old pavement joints as their test subject.
Six slab joints were treated with PoreShield™ while the other joints were left untreated. Additionally, previous methods including backer rods and silicone were removed. However, these previous methods were left in place for the surrounding joint areas as an additional comparison point. Application was quick and easy, using a backpack sprayer. And because it is low VOC product, no protective gear was needed. After three hours, the highway was reopened to traffic.
Nine years later, the results were remarkable. Sections treated with PoreShield looked virtually the same as the day it had been applied. The control sections, including the surrounding joint areas with rods and silicone, showed signs of significant deterioration and would likely need replacement soon.
The results from this first real-world test of PoreShield help to prove that the roadways of our states and cities can be protected for the long haul. Minimizing repair and replacement costs. And getting the lifecycle from concrete projects that you should expect.
