摘要
A system for evaluating properties of an asphalt sample includes a load frame and a test fixture. The load frame includes a platform and a loading rod. The test fixture includes: a base configured to rest on the platform of the load frame; first and second spaced apart vertical guide bars extending upwardly from the base; a horizontal cross bar above the base and extending between the first and second guide bars, wherein the asphalt sample is configured to be held between the base and the cross bar; a load plate above the cross bar, the load plate configured to receive the loading rod of the load frame to apply a load to the asphalt sample; a load cell above the base and configured to measure the applied load and to generate corresponding load electrical signals; and a controller configured to receive the load electrical signals.
