Perspectives on using basalt fiber filaments in the construction and rehabilitation of highway pavements and airport runways

Abstract

With the ageing transportation infrastructure, many transportation agencies across the world are focussing on rehabilitating and improving existing pavements. This means more roadwork on pavements open to vehicular traffic. Considering the rapid increase in both traffic volume and intensity in recent years, the work conditions on pavements have become difficult. Thus, there is an important need to design and construct long-lasting pavements that possess high durability, appropriate roughness or smoothness, and that which helps achieve greater time interval between repairs. The use of basalt fibers has shown to improve the durability and mechanical properties of concrete and asphalt mixtures through dispersed reinforcement. This paper presents new data and insights on the use of basalt fibers in concrete and asphalt mixtures acquired from theoretical and experimental research studies that can be useful in the design, construction and rehabilitation of highway pavements and airdrome runways.

Protection Parameters against the Cracks by the Method of Volume Compensation Dam

“…Thus, by plunging into the dam of additional volumes of piles will be compensated all strain elongation until the moment of their complete damping that will completely exclude the possibility of appearance the hazardous cracks for the dam [22][23][24][25][26].…”

“…Where ‫ݎ‬ -sectional radius of the pile, ‫ܧ‬ ୡ୭୫ and ߤ -modulus of deformation compression and coefficient Poisson for soil around the pile, ‫ݎ‬ -the distance from the point considered in the soil to the pile axis, ܴ ୢ -the radius of the deformed zone of soil around the pile at her pile, taken equal to half the maximum distance between adjacent piles [25][26][27].…”

Investigating the Effects of Chopped Basalt Fiber on the Performance of Porous Asphalt Mixture

“…Previous studies have shown that organic fibers have some disadvantages such as low strength and modulus, poor resistance to high and low temperatures, and high water absorption. Besides, they also present degradation, oxidation reaction, and curling problems during mixing and paving process [7,11,12]. e chopped basalt fiber is made of natural basalt rocks, which are broken and thrown into a melting furnace.…”

Vertical Displacements Measuring Methods During Bridge Load Tests

“…They enable us to verify the theoretical assumptions, as well as determining use factors which so affect the capacity of the construction they cannot be predicted theoretically. When observing a bridge structure, vertical displacements are very important because they have the biggest impact on the structure and its eventual deformation, while the horizontal displacements are tested especially in the case of rail lines and in more demanding engineering measurements of deformation [1][2][3][4][5][6][7][8][9][10][11][12][13][14][15][16].…”
