Asphalt factory, three level chemical quality assurance (certification), asphalt

Applications in civil engineering asphalt manufacturers, bitumen is widely used waterproof materials and anti-corrosion materials, mainly used in roofing, flooring, waterproofing underground structures spot asphalt, wood, anti-corrosion steel. Asphalt or road engineering cement pavement structure widely used material, which is different from the composition of mineral materials according to the proportion of asphalt pavement can be built with different structures, highways applied more widely. Modern Eirini d'Eyriny written doctoral dissertation in 1721 on the cover 1712 Shandong asphalt, Greece Eirini d'Eyriny doctors in Switzerland Val de Travers discovered huge reserves of bitumen mine. At first he just interested in the medical use of asphalt. However, due to the characteristics of bituminous asphalt as an excellent engineering materials, he eventually wrote his thesis in 1721 "on the asphalt of the doctoral thesis" (Dissertation sur L'Asphalte ov Ciment Naturel) and begin to lay the foundation for the study of modern asphalt technology. After three hundred years (1712 --1986 years), I do not know how much is located in Val de Travers asphalt by the total length of over 100 kilometers of the intricate maze of mine tunnels, they are mined and sold around the world.
