The Concrete Technical Community of Interest is a group of professionals (both AMPP members and nonmembers) that will include, owners, manufacturers, consultants, contractors, and others from various industries (Bridge, oil, gas, marine, rail, etc.) who have come together to share and discuss issues affecting the concrete industry and new and emerging technology in materials for both surface preparation, coating application and quality assurance, and quality control. Through the shared knowledge of this diverse group, both geographically and from varying viewpoints, information can be discussed about current issues for both the design phase and construction phase as they relate to surface preparation, coating application, and inspection. This can include the proper selection of materials during the design phase and contract specification development for the construction phase. The sharing of knowledge on how to deal with those issues and new technologies to protect those concrete structures with the newly applied coating system can be discussed and how they can be incorporated to streamline those processes and possibly lower the overall costs.

Road asphalt effect on potential readings

  • 1.  Road asphalt effect on potential readings

    Posted 12-09-2022 09:22 AM
    Hello,
    I have a base slab that has cathodic protection both on top and bottom. 100 m V shift is easier to achieve on the bottom of the slab than on the top, where asphalt was recently laid. Before asphalt, 100mV could be easily reached even on top of the slab. Does newly laid road asphalt affect the cathodic protection of reinforcement steel?
