Maoming Petrochemical Donghai asphalt indicators Class A Quality index: Project Quality Index Test Method penetration (25 ℃, 100g, 5s), 1 / 10mm 60-80 GB / T 4509 ductility (15 ℃, 5cm / min), cm not less than 150 GB / T 4508 Softening Point (method), ℃ 46-54 GB / T 4507 Solubility (trichlorethylene),%, not less than 99.5 GB / T 11148 Flash point (open), ℃ no less than 230 GB / T 267 Density (25 ℃), g / m3 1.00-1.05 GB / T 8928 wax content,% (m / m) is not greater than 2 SH / T 0425 film oven test (163 ℃, 5h) GB / T 5304 mass loss ,% not more than 0.5 GB / T 5304 penetration ratio,% no less than 68 GB / T 4509 ductility (25 ℃, 5cm / min), cm not less than ﹊ GB / T 4508 Class B Quality Index: Project Quality Index Test The method of penetration (25 ℃, 100g, 5s), 1 / 10mm 60-80 GB / T 4509 ductility (15 ℃, 5cm / min), cm is not less than 100 GB / T 4508 Softening Point (method), ℃ 44-54 GB / T 4507 Solubility (trichlorethylene),%, not less than 99 GB / T 11148 Flash point (open), ℃ no less than 230 GB / T 267 Density (25 ℃), g / m3 report GB / T 8928 wax content,% (m / m) is not greater than 3 SH / T 0425 film oven test (163 ℃, 5h) GB / T 5304 mass loss,%, not more than 0.8 GB / T 5304 penetration ratio, not less than 55% GB / T 4509 ductility (25 ℃, 5cm / min), cm of not less than 75 GB / T 4508 Features: 1, extended height, strong plastic with good durability 2, after evaporation and needle penetration ratio, product homogenization and thermal aging properties 3, with low wax content, good crack resistance, good anti-brittle performance 4, high temperature stability, strong adaptability, strong anti-rutting use: apply to the construction of two or more high-level roads, too raw material suitable for emulsified asphalt and modified asphalt. Note: 1, in the transportation, storage period, should prevent water immersion 2. Do not mix different types and quality of the asphalt mix 3, should control the heating temperature of the asphalt is not too high, not too long 4, asphalt steam to humans harmful and should be used in fire prevention arrangements antivirus
