| Abstract: | The operating principle of HBL520 Automatic FWD is introduced. Its advantages of test speed, high accuracy and automatic control and so on are described. According to the comparison test between FWD and Benkelman Beam, test results indicate the deflection test data of FWD and Beckman Beam have good linear dependence relation under the same test conditions, and the formula for deflection test data conversion can be find, which provides a foundation for spread application of FWD in highway engineering test. |
