Mr.Hou jinlong, former vice President of China communications construction company LTD., deputy director and secretary general of the China highway and transportation society(CHTS), new director of the "community" presided over the meeting

Mr.Hou Jinlong said that basalt fiber has excellent road technical performance and has huge application space in the highway transportation industry, but at present relatively less application. The "community" will solve the practical problems such as low attention rate, promotion and application as soon as possible, to promote the knowledge, acceptance and application of basalt fiber technology over the industry, in order that basalt fiber will play the role of "material revolution" in road construction.

Advantages of basalt fiber: environmental protection, high road technical performance indicators, braod application

Hou Jinlong believes that basalt fiber has three advantages.

The first is environmental protection. Basalt fiber has the characteristics of resource conservation and environment friendly. Basalt fiber is made from a single material, crushed basalt, from a carefully chosen quarry source. The manufacture of basalt fiber requires the melting of the crushed and washed basalt rock at 1450 °C to 1500 °C. The molten rock is then extruded through small nozzles of platinum rhodium alloy bushing to produce continuous filaments of basalt fiber. In the whole production process, no industrial waste water, waste gas and other industrial wastes are produced, which is known as "new material in the 21st century".
The second is high road technical performance indicators comparing with other types of fibers such as lignin fiber, glass fiber, etc. It has excellent performance for example resistance to high and low temperature, chemical stability, aging resistance, water stability, electric and thermal insulation, etc. According to the current theoretical research, scientific research and engineering application, the production process and technology of basalt fiber applying on road construction are very mature, which can effectively reduce the problems of pavement cracks and ruts and greatly extend the service life of the pavement, having significant effects in improving fatigue resistance of the pavement structure, high temperature stability, low temperature crack resistance and water stability, etc. Meanwhile, the fibers can be produced into various types of products such as chopped yarn, geotextile and geogrid, composite bar, etc. showing excellent road technical performance and application prospect.

The third is wide range of application. Based on the first and second advantage, at the same time as one of the four major high-tech fibers in China, it is a key product of the “13th Five-Year” Strategy emerging industry. It has a wide range of application in national defense industry including aerospace, shipbuilding, weapons manufacturing, etc. it also shows multi-field application advantages and huge market prospects in many fields such as civil transportation, petrochemical, automobile manufacturing, road construction, and tunnels, etc.

The "community": the development of basalt fiber industrialization promoted by the integration of government, industry, school, research institution and user
Speaking of the meaning of the establishment of the community, Hou jinlong believed that "the establishment of the community is based on the great platform of academic exchanges of CHTS, without which it cannot be established." He said that the community is actually uniting all the best basalt fiber manufacturers, scientific research institutions, universities and colleges, national engineering research centers, etc. in China. It is to solve the practical problems of low attention to the basalt fiber industry, low propaganda and promotion, and difficulty in promotion and application by effectively integrating resources, and carrying out extensive technical exchange activities, and taking scientific research as a breakthrough point, market-oriented, industrialization as the goal. The Community reflects the integration of government, industry, school, research institution and user and follows the values that the participants, who are both implementers and contributors, but also the biggest beneficiaries.
Hou Jinlong said that the second meaning of the establishment of the community is to form a economies of scale and scale effect. Enterprise alone can not break through the market. After the scale is formed, the interests of the group can be formed and the development of the industry can be better promoted.
In addition, Hou Jinlong also believes that the promotion of this work can better serve the national strategies such as "four transportation", “powerful nation of transportation” and “The Belt and Road”. The next step is to further strengthen industry research. To promote the standardization, assembly, industrialization, factoryization, intelligence, and lightweightness of the transportation industry through the application of engineering construction, maintenance, and bridge engineering, and to promote the construction of quality engineering in the industry.
