Rapid Field Assessment of MICP/MIDP Test Sections

Test plots of slope stabilization via microbially induced calcite precipitation via hydrolysis of urea (MICP) and microbially induced desaturation and precipitation via dissimilatory reduction of nitrogen (MIDP) planned for this summer offer a unique, but time sensitive, opportunity to evaluate the potential of both of these technologies for mitigation of earthquake induced liquefaction. While the objective of these test plots is to evaluate the potential of these technologies for slope stabilization, the owner of the site has agreed to provide access for testing using the NSF National Hazard Engineering Research Infrastructure (NHERI) large scale shaker developed by the University of Texas to evaluate the ability of these technologies to mitigate liquefaction potential after the slope stabilization field test.
