An Experimental Investigation on Concrete with Basalt Rock Fibers

Basalt fibre is formed from basalt rock when melted at a high temperature making it a non-metallic fibre. Basalt fibre reinforced concrete are good fire resistance, strength and light weight. These properties making it highly advantageous in the future to the construction business. There are many applications of basalt fibre like industrial, bridges, residential and highway etc. Fibres of basalt rock are used to make Basalt fibre, is cheaper and have improved physicomechanical properties which is very similar to the fibre glass and the carbon. They can replace many expensive materials resulting in wide range of applications in the field. The raw materials are available in all countries, making their production very simple. The biggest difficulties of the concrete and cement industry’s can be solved by the usage of basalt fibres. It is also used as composite and in the aerospace, automotive industries and fibre proof textile. Basalt fibres have no hazardous reactions with water or air and are explosion-proof and non-combustible. No chemical reaction will be produced that may damage environment or health when in contact with other chemicals. Reinforced plastics and steel maybe replaced by the basalt base composites. One kg of basalt reinforces equals to 9.6 kg of steel. Differences in compressive strength and split tensile test for concrete with and without basalt fibre by using cubes and cylinders are studied in this paper.

二次元画像解析ソフトによるポーラスアスファルト混合物の飛散抵抗性評価

In the asphalt pavement of Japan, porous asphalt pavement has increased certainly with highway etc. However, the porous asphalt pavement has a main problem that pot holes occur by aggregate scattering. The author focused on the particle size of 9.5 mm of the aggregate that are used with the porous asphalt mixtures and investigated about the fluctuation of aggregate scattering. As a result, this research confirms that the difference of aggregate particle size are influencing aggregate scattering by the method of Cantabro test. Furthermore, it was inspected that the difference of the contact of aggregate is influencing the scattering of aggregate by two-dimension image analysis software (iPas). ポーラスアスファルト舗装の施工実績は、全国の高速道路をはじめとして着実に増えてきている。しかしながら、供用後の主だった破損形態として，骨材飛散からくるポットホールがポーラス舗装を破壊する最大の要因となっている。そこで本研究では，ポーラスアスファルト混合物を製造するときに起こりうる骨材粒度のばらつきを想定した混合物についてカンタブロ試験を行い、粒度の違いにより損失率に差が出ることを確認した。また、そのメカニズムを各骨材間の接点数によるものと仮説を立て，アメリカ合衆国のウィスコン大学に設置されている、Modified Asphalt Research Centerのwebサイトにある、アスファルト混合物の二次元画像解析ソフトウェアiPasを利用し、その仮説の検証を行った。

A Recommendation System of Highway ETC Card Based on Decision Tree Theory

With the promotion of social information construction and the rapid update and replacement of large capacity storage equipment, the amount of data from every field grows exponentially. Reportedly, the amount of the data accumulated by Shandong Hi-speed Group is very large. These data can satisfy us some daily usefulness, such as query, retrieval, statistics, statements etc. But what is more important is that how can we discover some useful information from the information ocean. This information can be used in real life such as auxiliary decision. This paper is proposed in this historical background. Data mining is a powerful tool for acquiring knowledge from massive data. Some methods of data mining, such as decision tree, support vector machine, Bayesian decision theory, artificial neural network, k-nearest neighbor, association rule mining etc, are commonly used. In this paper, we design a recommendation system of highway ETC card by using the theory of decision tree. The recommendation system can predict whether a car owner is a potential ETC customer or not through the analysis of the vehicle information. Experiments proved that the accuracy rate of the recommendation system is larger than 90%, so it can provide effective information for the extension of China's ETC card.

Application Analysis of Internet of Things in Intelligent Transportation

The three kinds of applications of Internet of Things (IOT[) in intelligent transportation are firstly introduced on the whole. Then the highway ETC system and RFID parking management system are expounded. The basic principle, system composition and the system workflow of RFID parking management system in detail. The thorough analysis of the parking management system will provide reference for the future application of IOT in the intelligent transportation field.

Characteristics of the Highway Architecture Design

The traditional highway development even pays more attention to the technique index of the highway, emphasizing the service ability and the service quantities and to for national economy. Usually emphasized" technique" factor for the highway but neglected the peoples request of environmental protection, cultural, region, art and other comprehensive factor. This paper put forward the concept, contents and characteristics for the highway architecture and the highway architecture design, to leads into the public building design theories and methods, and to modify the idea of design and construction for highway. The highway architecture is to study the highway buildings structure, function, environments and pepoles activity etc. certainly also includes two aspects of technique and art. The highway architecture design is the space design for highway buldings to satisfy various basic functions of highway and moderates the foundation of various factors, such as the highway buildings and environment etc.

Deposit Slope Failure Analysis and Prestressing Loss Study of Anchorage Cable

Slope project is often appearing in rock and soil engineering such as water conservancy, mine, highway and railway etc. And deposit slope is a special natural one. For probing into slope failure mechanism and prestressing loss of anchorage cable in deposit body, this paper researches it by numerical simulation. Study result shows: First, three leading influence factors, which are deposit slope lithology and structure, in-situ stress, and groundwater, may induce slope failure; Second, slope failure patterns chiefly includes landslide along the interface between bed rock and deposit, and part circular slippage in shallow deposit body; Last, it appears prestressing positive loss and negative loss of anchorage cable in study area, especially the latter occurs because of the slide interface existing in deposit body, and changing technical parameters of anchorage cable can partly improve prestressing loss.
