These days, there seems to be an Association or Institute for everything. There is even an Asphalt Institute. Their Web site has information that can be useful to our clients’ car wreck cases, especially when big rig or 18-wheeler trucks are involved. In those cases it can be important to prove braking facts, using coefficient of friction calculations. The type of pavement at the scene of the collision obviously affects the calculations, and you can learn all about pavement at the Institute’s Web site.
