Introductio
"Ten Questions and Ten Answers of Basalt Fiber Series" is a common science article based on material provided by CHTS collaborative innovation community of basalt fiber pavement industry. It is hoped that it can deepen your understanding of basalt fiber road material and solve practical problems in engineering.
Q1:
What are the main applications of basalt fiber in highway engineering, what are the advantages of road performance, and what is the core functional positioning?
(一)4 main applications in highway engineering
Chopped basalt fiber reinforced asphalt concrete pavementChopped basalt fiber reinforced cement concrete pavement
Basalt fiber rebar reinforced highway pavement and bridge deck pavement
Basalt fiber geogrid reinforce the foundation of highways and overpasses
(二)Advantages of road performance
01 Performance advantages of basalt fiber asphalt concrete pavement1 The ability of anti-fatigue and cracking increased by 2~6 times
2 15%~30% Cracking resistance under low temperature increased by 15%~30%
3 Anti-rutting ability increased by 25%~40%
4 Pavement resistance to water damage greatly improved
02 Performance advantages of basalt fiber cement concrete pavement
1 Compressive strength increased by 10%~20%
2 Shear strength increased by 20% to 50%
3 Flexural strength increased by 25%~50%
4 Impermeability up to level S12
5 Anti-freeze performance meet the requirement of 300 times rapid freeze-thaw cycle
6 Impact toughness increased by about 2 times, and the number of fatigue cycles increased by 1 ~3 times.
03 Other advantages
Rebars, composite mesh, geogrids used in highway subgrade or bridge deck have the advantages of chloride corrosion resistance, high strength, durability and so on.
(三)Core functional positioningTo restrain fatigue damage and postpone major or minor repairs.
The design service life of highways can truly be 15 years
