The Asphalt Pavement Maintenance Technology In Congo

Congo is located in the central and western Africa,the official language of French,land area of 342,000 square kilometers,population 4.2 million.Congo is currently 1,200 km asphalt road,due to the backward economic and cultural development,the country lacks the available asphalt pavement conservation norms,making the asphalt pavement disease is not timely and effective conservation treatment,seriously affecting the transport capacity and economic development The Therefore,this paper has been applied to the curing technology of Congo(Bubble)asphalt pavement,which has important technical guidance significance.On the basis of summarizing the types of asphalt pavement diseases in Congo,this paper analyzes the causes of asphalt pavement diseases,combined with the local conditions of Congo,and the reference to China's asphalt pavement conservation technology.Pavement surface condition index(PCI),riding quality index(RQI),rutting depth index(RDI),skidding resistance index(SRI)and pavement structure strength index(PSSI)were used to analyze the asphalt pavement quality or performance.Based on pavement quality or performance index(PQI)proposed the asphalt pavement maintenance decision-making program.Finally,the analysis of asphalt pavement daily maintenance technology,common disease maintenance,overcoat conservation technology,renovation and recycling technology and overhaul reinforcement technology..For the effective promotion and application of master's thesis in the Congo(cloth)translated into French.The research work of this paper provides useful reference and technical support for the conservation of Congo asphalt pavement.
