As a high-strength, durable and lightweight reinforcing material, road fiber can significantly improve the mechanical properties of asphalt pavement, thereby extending the fatigue life of the pavement structure.Severe early damage to asphalt pavement is related to external factors such as long-term

Low dosage and high water reduction rate;The slump loss over time is small;The effect is significant: the 3-day compressive strength of concrete is increased by 50-110%, the 28-day compressive strength is increased by 40-80%, and the 90-day compressive strength is increased by 30-60%;Concrete has ex
