Maintenance Equipment Distribution Principles And Proposal Distirbution Standards Of Inner Mongolia Highway Asphalt Pavements

Recently, highway constructions and transportations increase rapidly with our economical speed continuously developing, so traffic flows of highway increase greatly. Especially, add of overload vehicles heavily exceeds bearing capacity of design. Overload transportations shorten the period when highway defections appear. Defections frequently appeared in the early stage have affected vehicle running speed,safe and decreased traffic ability.In order to change this situation,repairing must be made to entirely renew the appearances and performances of the pavement. So, it is obvious that maintenance is very important for asphalt pavement constructed. At the same time,scientific and reasonable distribution of maintenance equipments can greatly increase managing quality, benefit,efficiency and maintaining cost.According to environments, climates, geology conditions,traffic flows,constructions of pavement,this thesis has analyzed and summarized types of defections and maintenance technology in the high-level and cold, dry, high-level semi-moist, semi-dry zone of Inner Mongolia and incorporated with researching information at home and abroad to determine maintenance equipments which can accord with requirements,decrease the maintenance cost and increase the maintenance qualities; it can study distribution proposal standard and reasonable choosing plans; it can increase management qualities, benefit and efficiency and to decrease maintenance cost,avoiding blind purchasing and sufficient as well as insufficient distribution.
