In recent years, with the gradual deterioration of air quality and with the more and more frequency of haze weather phenomenon, it intrudes into the human body and brings great harm to human health when people are unprepared. The basic theory that anion could purify air and eliminate positive ion explains that anion balata modified bitumen could reduce PM2.5, and the number of anion pavement release relates to the air purification. At the same time, building materials plaza and pavement materials with many functions were designed which can release negative ions, eliminate PM2.5 particles, and decompose harmful components of fuel vehicle exhaust. 1. Introduction There are 30 areas, cities, and provinces, which were shrouded in the four-haze process in January 2013. However, there were only five days without haze in Beijing [1]. The report shows that only less than 1% of cities have achieved air quality standards recommended by the World Health Organization (WHO). At the same time, seven of the world’s ten most polluted cities are in China. The gradual deterioration of air quality and more and more frequency of haze weather phenomenon would cause respiratory diseases, cardiovascular system, blood system diseases, reproductive system diseases, and so forth, when people are not prepared, for example, sore throat, emphysema, asthma, rhinitis, bronchitis, and other symptoms. It will lead to lung cancer, myocardial ischemia, and reperfusion injury in the long term in this environment. The main components of the haze are sulfur dioxide, nitrogen oxides, and particulate. The first two belong to the gaseous pollutants; particulate matter is finally a heavier fog and haze pollution culprit. There are toxic particulate matter sources in cities. First, it is the automobile exhaust. Second, it is exhaust gas burning coal for the winter heating in the north, and industrial production emissions, such as metallurgy, furnace or boiler, electrical, mechanical manufacturing industry, and a large number of automotive paint and building materials production furnace combustion emissions. Finally, dust was caused by the construction sites and road traffic. The negative ions in the air are called air vitamin, environmental health guardian, which can purify the air. It is beneficial to human health [2, 3]. The negative ion in the air is a single molecular and light ion clusters. The negative ion mainly includes hydroxide ion, oxygen anion, and carbonate ion, but the proportion of oxygen anion is large and relatively stable. In nature, the source of negative ions is mainly to stimulate the universe, sun rays, and radioactive elements in rock and soil release radiation as well as the lightning excitation, storm, waterfall, the wave friction, and other factors. In addition, the decomposition of rain water and forest and plant photosynthesis made more oxygen-enrich air. However, artificial negative ion mainly uses high voltage electrostatic field, high frequency electric field, ultraviolet radiation, and radiation to hit water in order to make the air ionization and produce negative ion. In recent years, people found that some inorganic oxide composite powder induced negative ion in the air; some rare earth compound salt also has led to the air ionization function. The negative ions in the air have a positive effect on the growth of the body and preventing disease. (1) Anion can improve the lung organ function and respiratory villi cleaning efficiency. (2) Aoion can reduce blood 2 pressure and enhance myocardial function. (3) Anion can reduce strong oxidation. Negative oxygen ions can destroy bacteria’s cell membrane or the activity of cells bioplasm active enzyme, so as to achieve the purpose of antibacterial sterilization. (4) Aoion can encourage people’s spirit. It could increase body alertness and enhance people’s imagination, which could improve work efficiency at the same time. (5) Aoion can strengthen the immune system function. The results of the study show that nocturnal sleep in pyjamas with negative ion emission function will reduce to some extent the rectal temperature of the human body, improve the quality of sleep, and improve human immunity [4–6]. Thus, negative ion and human health are closely related, especially in the increasing pollution today. At present, PM10 is one of the important general pollution indices in the assessment of atmospheric environment quality. When the environment aerodynamic diameter is less than 2.5 𝜇m, it is called PM2.5 [7, 8]. At present, people gradually realize that the particle size under the 10 𝜇m endangers the environment and human health; in particular, PM2.5 pollution is the most serious one. In this paper, Gu Haiyan is adopted for nanometer ion additive to prepare road asphalt material. Gu Haiyan not only looks gorgeous but also has nano-single crystalline, nanosphere, nanofiber, and nanosheet layer. Of course, the important function is to release anions. Gu Haiyan can radiate infrared light with a wavelength 8–15 𝜇m at ambient temperature 20∘ C, and the normal emission rate is 0.88. Since far infrared ray is very close to vibration frequency of human body cellular elements, as long as “Life waves” permeate into the body, it will cause resonance between atoms and molecules in human cells, through the resonance absorption and the heat after the friction between molecules and it will form thermal reaction, thereby promoting the rise of subcutaneous deep temperature, expanding blood capillary, and accelerating the blood circulation. It is beneficial for clearing vascular accumulation and the harmful substances of the body, removing obstruction to hinder metabolism, and reviving the organization. And then it will promote the generation of enzyme in order to activate cells, prevent aging, and strengthen the immune system. Therefore Gu Haiyan is a kind of precious stone and natural nanomineral materials. 2. Main Materials and Methods 2.1. Main Materials.
