Recent research suggests that China’s Belt and Road Initiative (BRI) would improve the bilateral trade between China and its partners. This article uses detailed bilateral export data from 1990 to 2017 to investigate the impact of China’s BRI on its trade partners using neural network analysis techniques and structural gravity model estimations. Our main findings suggest that the BRI countries would raise exports by a modest 5.053%. This indicates that export and network upgrades should be considered from economic and policy perspectives. The results also show that neural networks is more robust compared with structural gravity framework.

The West, chiefly Europe, left political footmarks in Africa from the Colonial Era, along with varying economic footprints and surviving engagements in the immediate Post-colonial Era. However, the relationships between Africa and her former colonial masters have hardly yielded much to the former following the wave of independence, leading to the perception of failed relationships. This perception of failure to deliver on their undertakings has left Africa with only one option—China. The latter has been addressing some of Africa’s urgent infrastructure needs in return for natural resources and agricultural products. These engagements on the surface appear to be good business, but on further examination seem questionable notably as it relates to debt distress on vulnerable economies. To increase her footprint within the continent, China extended her Belt and Road Initiative (BRI) to most African nations who have signed a memorandum of understanding for future development projects. Though the commitments usually are unspecified, China’s investments have seen rapid growth since the early 2000s, largely owing to the implementation of the BRI. The memoranda have had the potential to strengthen ties with partner nations. The expansion to include Africa in its economic participation in the BRI has left the West questioning China’s motives while reinforcing suspicions about possible future US-China conflict. The impact of BRI on the African continent is quite visible in all the subregions, especially in their improved gross domestic products. A burning question has been whether these partnerships represent win-win relationships for sustainable growth or debt-growth dynamics.

The softening point of modified asphalt is an extremely important indicator to evaluate the high-temperature performance; its the temperature of modified asphalt sample emerging shear deformation under the action of certain shear stress according to the specific heating rate. Its found that in the actual construction and testing, different temperature conditions has a larger impact on the softening point of the modified asphalt, which has adverse affect on road construction. This paper studied and researched the influence of temperature on modified asphalt softening point indicators from the different test temperature, including packing compact temperature, scraper temperature in removal of asphalt that above test mode, standing temperature, curing temperature and initial heating temperature before test.

AbstractThe research measures the driving force of innovation in economic structure transition. In order to change the pattern of economic development, China is implementing a strategy of innovation-driven development. China’s capacity of innovation has been increasing, especially since 2012, and China’s innovations have taken a leap-forward development. Nowadays, innovation has become a main driving force in China’s economic development and hi-tech industries particularly make a great contribution. Although China’s tertiary industry has been dominant and its share in three industrial sectors has been exceeding 50% since 2015, a problem still exists in China’s economy that the proportions of primary and secondary industries are relatively higher compared with developed countries. In this paper we use PLSR model to measure the impact of innovation on China’s economic structure transition. It is found that innovation can expand the tertiary industry through shrinking the proportions of primary and secondary industries, transforming China’s economic structure into a more advanced pattern. Additionally, China is also devoting itself to the “Belt and Road Initiative”, which should be combined with China’s domestic innovation-driven development and realize sustainable development of economy worldwide.

Construction dust falls to the snow cover and the surface of the glacier to form a fouling layer to absorb more solar radiation and reduce the intensity of surface albedo, thereby accelerating the melting of the glacier, which is the main factor affecting the glacial environment in the Highway construction. This article adopts the combination method of wind tunnel experiment and numerical simulation was used to calculate the impact range of construction dust. The results show that with increasing of particle size, the diffusion range of dust decreased while the settlement speed increased. High dust concentration area (> 4mg / m3) is generally distributed within 1000m around the construction site. The specific extension direction is directly related to the local terrain and wind direction, and the height direction is generally not more than 300m. According to the above simulation results, for preventing and reducing the impact of highway construction on the glacial environment, the requirements of route selection and construction dust control measures was put forward, which played an important role and significance in guiding the highway design and construction and reducing the impact of highway construction on the glacial environment.

Industrialization is the key to the growth of any country’s economy. However, on the other hand, the production of industrial waste is increasing enormously, which adversely impacts the environment and natural resources. Red mud is also a widespread industrial waste produced during aluminium extraction from bauxite ore in Bayer’s process. Red mud is a highly alkaline material that creates a massive environmental threat in nature. To reduce the impact of this solid waste material, the ideal method is to use it in construction works with appropriate stabilization. This study envisages the strength properties of red mud with fly ash and cement to use it as a road construction material in the subgrade. The influence of fly ash and cement on improving the strength properties of red mud was studied in detail by replacing red mud with 10%, 20%, and 30% with fly ash and 1%, 3%, and 5% of cement to its dry weight. The CBR (California bearing ratio) value was increased from 1.58% to 11.6% by stabilizing red mud with fly ash and cement, which can be used as a road construction material. The UCS (unconfined compressive strength) of red mud was increased from 825 kPa to 2340 kPa upon curing for 28 days with the right mix of fly ash and cement. Along with the strength properties, the chemical analysis of leachate for the best suitable mix was performed according to the TCLP method to understand the hazardous materials present in the red mud when it is injected as ground material. Both strength properties and the leachate characteristics prove that the red mud with suitable fly ash and cement is an excellent material in road constructions.
