Based On The Cement Concrete Pavement Overhaul Maintenance Petrochemical Project Application Research

Cement concrete pavement because of its high structural strength,long life cycle,easy maintenance and other characteristics of the world has been widely used as the current road structure of one of the main forms.However,with the economic development,the increase in vehicle load,coupled with the majority of China's existing cement concrete pavement has reached or near the useful life of cement concrete pavement damage is more and more serious,while its maintenance period Longer,but also reduces the ability to pass the road,which are limited to the development of cement concrete pavement.At the same time for the original concrete pavement overhaul is also inevitable.At present,the application of cement concrete slabs in the project is mainly crushing and crushing,but the use of the traditional method of stabilization and fracturing is not very satisfactory because of its incomplete crushing of the road and broken After the uneven particles,etc.,after the transformation of the road structure is easy to produce a variety of diseases.The crushing technology is the most popular at home and abroad a kind of old concrete pavement broken technology,because of its broken quality easy to control,a broken shape,and so on,and has been widely used.As many of the cement concrete pavement has been unable to meet the needs of transport,and simple maintenance can not control the development of the disease,therefore,must be converted or overhaul.Based on the present situation of cement concrete pavement,this paper studies the application of crushed petrochemical technology in the reconstruction of cement concrete pavement based on the highway overhaul project of Route 203(Yu Lu junction to Zhang Guan Temple).At the same time,the change of strength and stability of the layers after the asphalt concrete was added on the basis of the crushed layer.Engineering practice shows that the old cement concrete pavement transformation technology can greatly improve the road running quality,can effectively solve the overlay reflection cracks,destruction of the road to extend the life of the road,with good economic and social benefits.
