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.
