The Damage Overweighed Vehicles To The Highway Road Face And Its Prevention And Cure Measures

In recent years, Shandong Province Expressway rapid development of the province provided a highway to facilitate the transport conditions, the same time promoting the development of the automobile industry. Large vehicles and trains the proportion of significant improvement to transport operators to win a higher economic efficiency, especially for large transport vehicles, will be several times higher than the average vehicle cost-effective. However, with the overall socio-economic development, capacity, load unbalanced development, Tariff system deformity, With profits caused transport overloading of the increased phenomenon prompted overloading increasing gravity on the highway facilities caused great damage.Due to the excessive use of Highway disorderly resources, the large number of overloaded vehicles rolled over, Highway pavements ahead of a large area of cracking and breakage. Shandong is more of the original design life of 15 years, overhaul of the 10-year life of the highway pavement, 2-3 years after use have had to undergo major repairs, damage effects amazing. Overloading and overloaded vehicles have emerged, to the normal highway operation and maintenance caused tremendous impact greatly shorten the life of the highway and service cycle, to make serious property losses, Shandong Province as well as the image of highway construction has had a bad influence. Now, due to road transport heavy economic losses caused by the transport sector has been far greater than the economic benefits of households. Although China has introduced the relevant norms and regulations, but the implementation of which is not ideal, particularly heavy traffic on the road damage quantitative analysis would not have been able to conduct adequate testing on the spot. Therefore the heavy traffic on the roads damaged, corresponding preventive measures and solutions to the engineering and technical personnel is an urgent task. In this context, this paper, the heavy, overloading traffic on the road damage analyzed.This paper focuses on the heavy traffic on the road the extent of the damage, with the Shandong Province road characteristics, the formulation of reasonable restrictions on the transport vehicle standards, against heavy traffic characteristics, Highway road to take reasonable and effective conservation and management measures of road transport and road management to combine organic, States balance between households and the transport sector's economic interests of the countries have accumulated more highway maintenance funds to ensure that highway infrastructure intact. Ensure the smooth flow of road safety.By Shandong Province highway pavement performance of the investigation, representative of the Highway Pavement Performance conducted a comprehensive survey, a majority of the Jinan - Qingdao Highway, Beijing-Fuzhou Expressway in Shandong of the damaged roads, street intensity, Pavement, Anti-skid performance of the four basic indicators of the investigation and detection, as well as the use of road space for the properties were evaluated. Investigation on the road, on the basis of combining the two highway traffic volume of research and analysis targeted at the heavy traffic on these highways of actual operations. Comprehensive Analysis of the heavy traffic on the impact of the road system summarizes impact damage to the road surface, and the upgrade roads durability of the conservation measures and countermeasures.Based on overloading, overloading on road traffic injury qualitative and quantitative analysis, and the two investigations of the highway pavement, and Shandong Province with overloading the characteristics of the phenomenon, against the province to reduce the heavy, overloaded vehicles on the road that the damage made the following recommendations:Policy:The departments concerned should strengthen the sense of control overloading of the existing rules and regulations governing the work-obey the orders; use reasonable road fees policy study on road transport to the correct political orientation; study and formulate the tonnage level carton sizes, bearing pieces of tire specification limits; automobile test station operated vehicles to be regularly monitored to guard the gateway card issuing operations; on the main road set axle load limit detection system for heavy charges checking out overloading of vehicles and punished according to law; organized by the officials of the heavy traffic volume of traffic in the survey, management, compilation, for the design and decision-making based on the first-hand information;Engineering technology:(1) To the traffic forecast to intensify and accurately to the development of vehicle overloading and factors influencing changes;(2) Surface structure, material design needs improvements to enhance the mixture of asphalt pavement performance. Their main purpose is to raise high temperature stability, low-temperature cracking, road durability, water stability, sliding surface, watertight, Shear capacity;Adoption of this research:(1) According to the scene pavement performance and traffic investigation test, summed up our province and traffic overloading the total volume of traffic, the road structure to the theoretical calculation provided;(2) By theoretical analysis, structural strength, age, Deflection etc. synthesis heavy traffic out of semi-rigid and rigid pavement road factor;(3) System summed up in Shandong Province heavy traffic characteristics and the main preventive measures from a policy and engineering technology to solve both the heavy traffic.In this paper, the Shandong Provincial road surface of the heavy traffic, rational and effective means of control, other domestic Highway also has broad application.
