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 are presented for several crossings including a wide variety of conditions and loading intensities. The data serve to quantify pressure gradients within highway/railway crossings for application to structural design analyses.
