The purify air of embodiment 7 is tested
Rut plate is molded using bituminous concrete, rut board size is 30cm long, 30cm wide, 5cm high, respectively by embodiment
The road coating material of 1-5 and comparative example 1-3 is positioned over the blank rut plate for not brushing any road coating material
In closed tails assay equipment, vehicle exhaust is passed through, through after a period of time, using gas in exhaust analyzer test equipment
The change of content, result of the test is as shown in table 2.
The purify air result of the test of the modified asphalt concrete of table 2
From table 2 it can be seen that effect of the asphalt concrete of blank without purify air, its result of the test may
It is because test error causes.NO in vehicle exhaust can effectively be purified using the road coating material of purify air of the inventionX、
The gases such as HC compounds, CO, wherein to NOXPurification efficiency it is the most obvious, purification ratio between 80%~93.3%, it is right
The purification ratio of HC compounds between 29.3%~42.1%, to CO2Purification ratio between 22.2%~62.5%, it is right
The purification ratio of CO shows road coating material purify air effect is significant of the invention between 19.5%~27.0%.
It is obvious to a person skilled in the art that the invention is not restricted to the details of above-mentioned one exemplary embodiment, Er Qie
In the case of without departing substantially from spirit or essential attributes of the invention, the present invention can be in other specific forms realized.Therefore, no matter
From the point of view of which point, embodiment all should be regarded as exemplary, and be nonrestrictive, the scope of the present invention is by appended power
Profit requires to be limited rather than described above, it is intended that all in the implication and scope of the equivalency of claim by falling
Change is included in the present invention.
Moreover, it will be appreciated that although the present specification is described in terms of embodiments, not each implementation method is only wrapped
Containing an independent technical scheme, this narrating mode of specification is only that for clarity, those skilled in the art should
Specification an as entirety, the technical scheme in each embodiment can also be formed into those skilled in the art through appropriately combined
May be appreciated other embodiment.
