The Application Of Preventive Maintenance Technology In Highway

So far, China’s highway mileage has been on the second place in the world. As a nojuncture of continuous type pavement, The asphalt pavement has some advantages, such asgood mechanical strength, smooth driving, no dust, no vibration, low noise and easy tomechanization construction etc, and become the main structure form of highways and cityroads. And with the increasing mileage and extending the life of highway, our countryhighway transportation enterprise has been in rapid transitional stage, construction stage tothe maintenance and management.Highway construction is developing, then highway maintenance management is toconsolidate the existing development outcomes. In this sense, highway maintenance is also akind of development. Construction and maintenance are the two themes of the highwaydevelopment, construction is a positive development, maintenance is a sustainabledevelopment; Construction is the premise, maintenance management is the guarantee,construction creates wealth, maintenance protects wealth, the creation and accumulation ofwealth are equally important, so stick to build a equal and coordinated development. After theconstruction of large-scale, is ultimately large-scale maintenance. In the face of growingmaintenance requirements and limited maintenance funds, aiming at the shortcomings of thepresent highway maintenance technology and management, preventive maintenance arises atthe historic moment. Preventive maintenance is effective means to alleviate pavementmaintenance fund shortage and to improve the quality of pavement maintenance.Based on the research results at home and abroad, based on XinYang highwaymaintenance engineering, comparison and analysis the effect evaluation of four types ofpreventive maintenance measures, the micro table place, ultra-thin wearing course, SMAcover face and modified AC hot mix asphalt concrete surface. Has carried on benefit analysisof the preventive maintenance measures as well as their influencing factors. Finally, someSuggestions are given about XinYang highway expected maintenance scheme.
