Introduction

Interpretation of the National Standard of the People's Republic of China GB/T 38075—2019 Hard Road Petroleum Asphalt

Hard Road Petroleum Asphalt is an important road construction material. The GB/T 38075—2019 standard specifies its classification, technical requirements and test methods.

Product Classification and Specifications

According to the range of needle penetration (25℃, 100g, 5s), hard road petroleum asphalt is divided into four specifications: HA-15, HA-25, HA-35 and HA-45:

HA-15: needle penetration (1/10 mm) is 10~20
HA-25: needle penetration (1/10 mm) is 20~30
HA-35: needle penetration (1/10 mm) is 30~40
HA-45: needle penetration (1/10 mm) is 40~50

Implementation suggestions

Choose appropriate specifications:Choose hard road petroleum asphalt of corresponding specifications according to road grade and climatic conditions. For example, HA-45 can be selected in high temperature areas to improve ductility.

Quality inspection:Ensure that the products provided by suppliers meet the standard requirements, especially key indicators such as needle penetration, softening point and solubility.
