This invention provides a special testing machine for mechanical tests of road engineering material-bituminous concrete. On the same device, only by changing special pressing apparatus and fitting with corresponding sensors, MARSHALL, fracture bending and tensiles and 3 axis (closed pattern) tests under the control of a micro computer can be done automatically. For the whole dynamic process,record outputs of test results are given in a statistically processed numerical form and test parameters are given in a diagram form Guard fence is provided on the pressing apparatus in low temp. fracture test for the safety of staff and machine. |
