Road maintenance machinery use cycle

Road maintenance according to its nature of the project, size, technical complexity is divided into small repair maintenance, repair, overhaul and improve the four categories. Specifically divided into:

(1) minor maintenance works: the road and all of its engineering facilities for preventive maintenance and repair of its slightly damaged part, so that it is often in good condition. It is usually carried out by the maintenance of the road in a year of minor maintenance quota funds, the monthly (ten) arrangements for the daily work of the plan.
 
(2) repair works: the general wear and damage to local engineering facilities and local damage to the regular repair and reinforcement to restore the original state of small projects. It is usually organized by the grass-roots road maintenance agencies (year) plan and organize the implementation.
 
(3) Overhaul works to carry out periodic comprehensive repairs to the greater damage to the road facilities in order to fully restore to the original design standards or to local improvement in the original technical level and to build additional projects to gradually improve the road capacity. It is usually organized by the grassroots road maintenance agencies or with the help of its parent organization, according to the approved annual project budget.
 
(4) Improvement works The road and its engineering facilities are progressively increased in stages by means of unsuitable traffic volume and load requirements, or by improving the larger capacity to improve the capacity. It is usually organized by the regional road maintenance agencies or provincial road maintenance agencies in accordance with the approved plan and design budget to complete the implementation or tender.
