Extruded insulation board on the highway with its paved roadbed process is not complicated, xps extruded insulation board usually placed in the top permeable pellets, compared with the laying of ordinary embankment, when the road is more than put a layer of geotextile cover, with a level of crude Paving Face, xps extruded insulation board laid on top, then add a layer of reinforced concrete slab used as a protective layer to disperse the load of asphalt laid on top. Mainly because it can withstand greater traffic load, while its lightweight waterproof, xps extruded insulation board has a better foundation than normal ability to prevent the partial collapse of the road. Our extensive insulation board Which area, highway construction on China's economic development has a great significance. Another big advantage of using xps extruded insulation board as roadbed filler is low cost. And compared to natural soil to fill roadbed, since filling the xps extruded insulation board Further, subgrade xps extruded insulation board EPS packaging materials can be used to produce recycled materials. In addition, the settlement produced after the completion of road works small, long-term use without damage, so its less maintenance, low cost. According to China's road transport stages of development goals insulation board, to 2010, total mileage and strive to reach 2.1 million & # 8764; 2.3 million km, fully completed "five vertical and seven horizontal" national trunk insulation board equipment, high mileage reach 50,000 km. By 2020, the total mileage will reach 2.6 million & # 8764; 3 million kilometers. Highway mileage of 70,000 km or more, connect all the current population of more than 200,000 of the city, basically formed the national highway network. These hundreds of thousands of kilometers of road construction will subgrade development xps extruded insulation board the laying of a Sunshine Boulevard, the market is very promising. ** Office of Jiangsu Province, the Provincial Housing and Urban Construction Department jointly issued the "Jiangsu Province building's exterior wall material fire Interim Provisions" to regulate new construction, renovation and expansion of civil wall insulation fire protection design and use. When both the building's exterior renovation or change the use of function, should the regulations. The provisions from the date of issuance. The provisions for combustion performance level residential buildings and crowded places such as wall insulation building has become more strictly regulated. When no cavity between the building exterior insulation materials and primary wall, the decorative layer, the use of residential building height greater than 54m A-class non-combustible insulation material polyurethane insulation boards, building height of not more than 54m when using no less than B1 level hard burning insulation material. Set crowded places with A-grade building insulation materials, do not set the building crowded places, when the building height greater than 50m combustion performance of insulation materials for the A-level,
