Embodiment 1
[0096] The vehicle-mounted mechanical accumulative bump meter has the advantages of high efficiency, simple operation, and low cost, and is widely used in road construction. In this embodiment, a vehicle-mounted mechanical accumulative bump meter is used as a measurement tool for extracting road spectrum parameters. The test speed of a certain type of vehicle-mounted mechanical cumulative bump meter selected is 30~80km / h, the test amplitude range is -20~20cm, and the minimum resolution is 1mm. The bump meter can simultaneously output the cumulative bump value VBI (cm / km) And the international roughness index IRI (m / km) index.
[0097] On the campus of Nanling Campus of Jilin University, seven 100-meter-long roads are selected, numbered JL-1, JL-2, JL-3, JL-4, JL-5, JL-6 and JL-7, among which 5 road sections (JL-1, JL-2, JL-3, JL-4 and JL-5) are used for cumulative bump value VBI and generalized international roughness index IRI E The correlation relationship is established, ...
