Rut preventing device and method for long uphill section of asphalt pavement

Abstract

The invention provides a rut preventing device and method for the long uphill section of an asphalt pavement. The rut preventing device comprises a central control unit, a pavement temperature acquiring system, an automatic spraying system and a running safety warning system, wherein the central control unit analyzes and judges the received real-time temperature data and the received real-time traffic information, and controls the automatic spraying system and the running safety warning system to work; besides, the central control unit transmits the working state of the systems to a server in a remote manner through a 3G wireless transmission module; besides, the central control unit receives commands from the server. The rut preventing method disclosed by the invention is simple, rapid and highly efficient, and is low in cost; both of running safety and pavement maintenance are taken into consideration; the temperature of the asphalt pavement can be effectively lowered, so that the generation of ruts on the asphalt pavement can be effectively relieved, and the running safety and running comfort on the asphalt pavement under high-temperature conditions in summer are improved.

Description

technical field [0001] The invention relates to the field of road engineering maintenance, in particular to a device for preventing rutting on a long uphill section of an asphalt pavement, and also relates to a method for preventing rutting on a long uphill section of an asphalt pavement. Background technique [0002] Rutting is one of the main forms of early disease of highway asphalt pavement. Once the road surface is rutted, it will affect the comfort and safety of vehicles, and it will also accelerate the destruction of the asphalt pavement. High temperature is the most direct cause of rutting. It softens the asphalt and reduces the bearing capacity of the asphalt pavement. Especially in the long uphill section, the vehicle travels slowly and the load increases significantly, which accelerates the rutting. [0003] Looking at the technical means to solve the rutting problem at home and abroad, they are all based on the premise of passively accepting the high temperature...
