Foreign cement pavement disease and repair technology development in some developed countries internationally, concrete pavement construction early, long history. Since the 1920s, the world has carried out research on the cement pavement design theory and design methods, making the design theory are maturing, becoming more rational design methods. For cement pavement cracks and other common diseases, to carry out a number of fruitful research work repair, which can effectively control and avoid the occurrence of cracks in the cement pavement. Japan's handling of cement pavement crack such problems early has attached great importance to the impact of the construction process, the ambient temperature, humidity, wind speed and temperature of the cement pavement and other factors on the rate of water loss of cement, has been through years of observation and statistics presented Methods for preventing cement road due to water loss rate is too large to control cracks and specific control targets, this approach to water loss rate and the rate of shrinkage of the main indicators, according to the cement pavement moisture evaporation rate and cement temperature, ambient temperature, relative relationship humidity and wind speed to determine the rate of water evaporation through cement board temperature, atmospheric ambient temperature, wind speed observations, based on the size of the concrete floor hollowing water evaporation rate of repair, take appropriate health measures to control the rate of water evaporation caused by excessive drying shrinkage cracks. Factors considered in this control method is more comprehensive, early cracks in the cement on the road more effective control program in the United States in SHARI] conducted a study of cement pavement soft kerf technology and made significant progress. Since the 1970s, the late 20th century, Since, some developed countries have established and implemented pavement maintenance management system, are more representative of the California pavement management system, which was completed and implemented in 1978, features a more simple, it is essentially a road database; Arizona road management system is established under JohnZaniewskiN guide for network-level system with financial planning; Currently, the developed countries of the world have adopted the use of the scientific method for the continuous road surface quality follow-up observations; and timely forecast traffic trends in When the road changes to a certain limit, a modern take timely conservation measures, quick fix, make use of the quality of the cement road surface is always kept in good condition. Diseases and foreign cement pavement patching cracks on technology development process and repair measures, our method is mainly used in high-pressure injection technology, epoxy resin infusion technology, rapid hardening cement technology. In the late 1980s, the country began to study the crack repair technology, techniques used mainly after pouring cement mortar reinforced, increasing the area of ??concrete structures under load floor hollowing, re-built after the demolition, but also a very small structure using high pressure water jet technology. pm to 90 years, China fishes cement pavement crack repair technology research. The method adopted is mainly the northern region after paving along both sides of the cut-off seam 20-50cm wide single steel mesh, and then re-pouring of ordinary cement. From the results, pavement crack repair concrete, strip board strength to meet the requirements, but because of the different cement old age, leading to mix old and new tf strength, sticking between the elastic modulus, shrinkage factor hollowing different concrete floor cracks and old cement knot strength inadequate, resulting in the same, as well as insufficient adhesion strength between the old and the new cement, resulting in the formation of both sides of the crate after pouring two new cracks. Cement pavement crack repair technology, China is in the development stage, forming technology remains to be further studied and discussed. The Department of Science and Technology Co., Ltd. Henan can bridge from the sand for the cement pavement and cement pavement cracks and other construction programs handle production of cement pavement repair materials, products with high temperatures, abrasion and low maintenance costs, etc., resulting in concrete pavement repair works has been widely used. Cement floor hollowing processing, cement floor hollowing, Huineng bridge can be provided by the Department of Road and Bridge Technology Co., Ltd., Henan. The Department of Science and Technology Co., Ltd. Henan can bridge (www.hnlq88.com) strong, credible, in Zhengzhou, Henan chemical products industry has accumulated a large number of loyal customers. The company better work attitude and constantly improving innovative ideas will be able to lead the Department of Road and Bridge and you hand into the brilliant, for a better future!
