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.
Highlights
A highway pavement is an integral part of a road-transport complex developed in various countries
The principal feature of concrete mixture reinforced with basalt fibers is its high durability at all kinds of stress conditions and the ability to sustain large deformations in elastic condition (Gribniak et al 2015; Mahova, Grebenyuk 1980)
Use of fiber in cement concrete mixtures One of the most effective methods for improving the mechanical properties of concrete used in the construction and rehabilitation of highway pavements and airport runways is to reinforce it with fiber, a special construction filament acting as a reinforcing component at the microlevel
Summary
A highway pavement is an integral part of a road-transport complex developed in various countries. The principal feature of concrete mixture reinforced with basalt fibers is its high durability at all kinds of stress conditions and the ability to sustain large deformations in elastic condition (Gribniak et al 2015; Mahova, Grebenyuk 1980). 2. Use of fiber in cement concrete mixtures One of the most effective methods for improving the mechanical properties of concrete used in the construction and rehabilitation of highway pavements and airport runways is to reinforce it with fiber, a special construction filament acting as a reinforcing component at the microlevel. The results of numerous studies reported in the literature confirm a possibility of a wide-ranging use of permanent basalt fibers and rough fibers as reinforcing admixtures in concrete mixtures for construction purposes.
