example 1

[0033] The weight ratio of natural basalt aggregate asphalt concrete in example 1 is: 10-16mm basalt 38%, 5-10mm basalt 36%, 3-5mm basalt 8%, less than 3mm basalt 8%, limestone mineral powder 10%, modified asphalt The oil-stone ratio is 6.4%, and the amount of polyester fiber is 0.3%.

example 2

[0034] The weight ratio of the steel slag aggregate asphalt concrete in Example 2 is: 10-16mm steel slag coarse aggregate 38%, 5-10mm steel slag coarse aggregate 36%, and the rest are the same as the natural basalt aggregate asphalt concrete. The electromagnetic induction power transfer efficiency and road performance indexes of asphalt concrete with the same design gradation but different aggregates are shown in Table 1.

[0035] It can be seen from Table 1 that although the road performance indicators such as Marshall stability, water stability and anti-rutting stability of steel slag asphalt concrete have been improved to a certain extent, because the steel slag aggregate contains as much as 18.2% iron, the electric energy of the asphalt concrete Conduction efficiency decreased by 9.2%.

example 3

[0039] Example 3 is the above-mentioned natural basalt aggregate asphalt concrete, and example 4 is the above-mentioned natural basalt aggregate asphalt concrete specimen with a glass fiber grid with a grid size of 25 × 25 mm.

[0040] The anti-rutting performance indicators of the two asphalt concrete specimens are shown in Table 2. It can be seen from Table 2 that after the grid is added, the grid holes have a certain restraint effect on the aggregate, so that the anti-rutting performance of asphalt concrete can be increased by 30.4%. Due to the heat generated by the transmitting circuit, the temperature under the asphalt concrete seal is relatively high. Adding grids under the asphalt concrete seal can significantly enhance the high-temperature deformation resistance of the road surface under the action of vehicle loads, reduce the occurrence of road rutting, and at the same time The grid overlay is placed between the polymer concrete and the asphalt concrete, which also he...

Abstract

The invention discloses an asphalt pavement capable of providing a charging function for vehicles in a driving process. The asphalt pavement sequentially comprises an asphalt concrete sealing layer, a grille, a polymer cement concrete structure layer and a base layer from top to bottom, wherein the polymer cement concrete structure layer comprises an emitting circuit; an external alternating current power supply generates an alternating current electromagnetic field to realize the mutual induction with a secondary coil arranged in an underpan of a driving vehicle; an electromagnetic induction charging system is formed. The problem of insufficient cruising power of an electric automobile is solved. On the premise of not influencing the automobile driving, the driving distance of the electric automobile is prolonged; meanwhile, the possibly generated potential safety hazard of electricity leakage of the conventional manual direct charging type parking charging is also solved. The asphalt concrete sealing layer uses aggregates with low iron bearing rate; on the basis of ensuring road-use performance and structural intensity, the pavement structure thickness on an emitting circuit primary coil is controlled.

Description

technical field [0001] The invention relates to the field of new type electric vehicle charging, in particular to an asphalt road surface which can be charged while the vehicle is running. Background technique [0002] The rapid consumption of fossil energy in the world and the serious pollution caused by its use have made changing the energy structure an inevitable trend for the sustainable development of today's society. The energy used by automobiles is also facing the severe challenge of changing from traditional energy to clean energy. Electric vehicles using green and pollution-free electric energy have become the development direction of the automobile industry. However, the limited capacity of the on-board batteries of electric vehicles requires parking and charging, which seriously restricts the development of electric vehicles. Therefore, it is urgent to develop new technologies for convenient charging of electric vehicles. Charging electric vehicles during drivin...
