Description

Technical Field

[0001] The utility model relates to the technical field of asphalt pavement construction equipment, in particular to an asphalt pavement anti-segregation device. Background Art

[0002] Asphalt pavement segregation is a type of highway disease. The specific cause is the uneven properties of the asphalt mixture in a certain area, which leads to the void ratio of the pavement during actual construction, thus accumulating and forming diseases. The early manifestations are deformation, potholes, local rutting grooves and cracks.

[0003] In the current method, the main way to prevent and control the segregation of asphalt pavement is to perform homogenous mixing during the initial construction. High-quality homogenous mixing is the most important prevention and control method. However, the existing technology has the following problems: most of the asphalt is stored in a storage tank or a mixing tank during construction. However, since the equipment with a mixing tank is expensive, it is generally equipped with an ordinary asphalt tank truck. The long-term static storage of asphalt in the tank truck will cause the occurrence of asphalt segregation.

Specifically, the receiving hopper 10 can input the paving asphalt into the two groups of mixing tanks 20, and each group of mixing tanks 20 is provided with a long rod stirring assembly 30. The long rod stirring assembly 30 can stir the paving asphalt in the mixing tank 20 to delay the segregation of the paving asphalt; The advantage of the long rod stirring assembly 30 is that, firstly, asphalt has viscosity. Under the homogenous mixing of the long rod stirring assembly 30, the degree of homogenous mixing can be effectively improved, and the present solution can realize homogenizing operation at the construction site, and the segregation phenomenon caused by the static asphalt can be restored by homogenous mixing; in addition, the main paving trough 40 is arranged between the two groups of homogenizing troughs 20 to receive the paving asphalt from the homogenizing trough 20; the main paving trough 40 is evenly provided with guide components 50, and the guide components 50 are used to guide the paving asphalt to the paving position, and the upper asphalt layer of the road surface during construction is laid by paving the main paving trough 40 and guiding the guide components 50.
