利用渗透等级沥青优化道路耐久性：交易商和建筑公司的指南
Penetration grade bitumen, including 60/70, 40/50, and 85/100, plays a crucial role in road construction and maintenance. Their penetration value will determine the grades, which indicates the hardness and suitability of the bitumen for various climatic and traffic conditions.
Types of Penetration Grade Bitumen
Bitumen Penetration Grade 60/70
PG 60/70 is one of the most commonly used in road construction. With a moderate penetration value, it offers a balanced blend of hardness and flexibility, making it ideal for temperate climates and standard traffic loads. The main advantage of 60/70 bitumen is its versatility. PG 60/70 performs well in both warm and cold temperatures, providing durable road surfaces. However, its general-purpose nature means it might not be the best option for extreme conditions. Click here to review the specifications of PG 60/70 grade of bitumen.
Bitumen PG 40/50
PG 40/50 is harder and less penetrative, making it suitable for high-stress environments such as heavy traffic roads or regions with hotter climates. This bitumen grade ensures that the pavement remains stable and less prone to deformation under heavy loads. While 40/50 grade bitumen is excellent for durability, its lower flexibility can make it more susceptible to cracking in colder environments.

Bitumen PG 85/100
PG85/100 is on the softer side, with a higher penetration value, which makes it ideal for colder climates where the pavement needs to remain flexible to avoid cracking. This grade is beneficial for road surfaces exposed to low temperatures, where flexibility is crucial. However, in warmer climates or under heavy loads, 85/100 bitumen may soften excessively, leading to deformation and ruts. Click here to review the specifications of PG 85/100 grade of bitumen.
Handling and Transportation for Traders and Construction Companies
Transporting bitumen effectively is as critical as choosing the right grade.
