As the most widely used basic asphalt, 70 # road petroleum asphalt has become the "main force" in the construction of ordinary roads in temperate and subtropical regions due to its stable high and low temperature performance and cost advantages. Penetration of the product 70-100(0.1mm), softening point ≥ 46℃, ductility (15℃)≥100cm, with good flexibility and aging resistance, it can adapt to medium and low traffic volume scenes such as urban secondary roads, county and township highways, parking lots and industrial park branches.
Bitumen # 70 strictly follows GB/T 15180-2010 standard production, high quality crude oil refining, through vacuum distillation process purification, harmful substances content is far below the national standard limit. With good construction fluidity (heating to 140-160℃ for paving), the construction efficiency is greatly improved, and the formed pavement is flat and smooth, which has been verified by one-year use. No obvious rutting, cracks, maintenance cost than similar products reduced by 15%.
