Standard Oil and the choice of the familiar asphalt asphalt technology indicators and quasi-use classification. Required to master grade asphalt division basis, ie penetration division, but should ensure that appropriate ductility and softening points. To select the 10th grade solid bitumen asphalt samples according to the project requirements, should be aware of the choice of bitumen grade (or softening point) principles and petroleum bitumen blending method. For example: Building bitumen (GB / T494--1998) on the 10th penetration (25 ℃, 100g 10 号 cheap solid bitumen, 5s) 10-25 ductility (25 ℃, 5cm / min) (cm) 10 号solid bitumen, not less than 1.5 Softening Point (R) (℃)> 95 Solubility (trichlorethylene, carbon tetrachloride or benzene) (%) on the 10th of solid bitumen wholesale prices, the evaporation loss of not less than 99.5 (160 ℃, 5h ) (%), not more than 1 evaporated penetration ratio (%), not less than 65 Flash point (open) (%), of not less than 230. Dongying asphalt road building on the 10th to Health New Materials Co., Ltd is mainly sold to various regions of the country, etc., for the majority of the needs of groups to provide attractive affordable, high quality and reliable construction on the 10th pitch. Quality construction bitumen price on the 10th, the 10th building asphalt sales price For other information, please consult our electricity.
