After decades of research and development, there have been a wide variety of modified road bitumen, waterproofing membranes and coatings, asphalt use, showing some practical effect. But given the price of the modified material 2 to 7 times higher than the average generally asphalt, materials engineering performance users have not been able to fully grasp, modified bitumen production slow growth. Modified road asphalt pavement is mainly used for applications runway, waterproof deck, parking lot, playground, heavy traffic roads, intersections and road bends and other special occasions. Europe will apply to modified asphalt road network maintenance and reinforcement, greatly promoted the universal application of modified asphalt road. Modified bitumen membrane for waterproofing and coatings mainly high-end buildings. In 1810, asphalt, in Lyon, Ma Ti quality asphalt overlay is first applied. After ten years of development in Genoa a predecessor of modern asphalt felt and application success. Based on extensive attempts, asphalt cheap, in 1837, Shandong asphalt, bitumen technology has been shown to use on the highway project. 1839 in the Austrian capital Vienna found by re-heating method can make asphalt recycling. 1838 was the first asphalted road appears in Prussia Hamburg. In 1851, 78-meter-long section paved with asphalt surface on the road from Travers to Paris. Just 20 years later, Paris was almost completely covered with asphalt, and soon after the development of this situation almost all major cities in Europe.
