Techniques are described for installing instrumentation within highway/railway crossings to measure vertical pressures under moving highway and railway loadings using earth pressure cells. Also, techniques are described for installing instrumentation between rail base/tie plate interfaces to measure vertical pressures under moving railway loadings using pressure sensitive ink sensors. In addition, the sensors were used to measure the surface pressures imparted by highway vehicles on crossing surfaces. Data is presented for several crossings including a wide variety of conditions and loading intensities. The data serves to quantify pressure gradients within highway/railway crossings for application to structural design analyses.
