Description
Technical field
The invention belongs to and the present invention relates to road maintenance technical field, be specifically related to a kind of asphalt highway maintenance process.
Background technology
In the last few years along with the quick increase of road Traffic Volume, truck ratio increases, and overloading is serious, such as pass by most of built semi-rigid pavement after being open to traffic 3 ~ 5 years, even just there is various early damage afterwards in 1 year in what have, wherein compares and common are crack, rut, be full of cracks, depression, bellding and hole groove etc.This has not only had a strong impact on communications and transportation, and causes huge economic loss.The maintenance of flexible pavement is also faced with the challenge more and more sternly completed thereupon.Highway maintenance is generally divided into preventive maintenance and toolability maintenance.The most of highway maintenance of current China only rests in toolability maintenance, such as benefit hole groove just belongs to toolability maintenance means, and at this time often the disease that degree is different has appearred in road, and major part is structural disease.If correctly can in time realize early stage defensive maintenance, will not dig pit groove or groove of digging pit less, enable road surface keep good using state for a long time.
Within 2000, AASHTO when describing preventive maintenance (preventivemaintenance) to its definition is: " Preventive maintenance for highway is a kind of planned strategy of cost-efficient measure; it is for built highway system and its ancillary facility; delay the time that it occurs to destroy; and keep or improve systemic-function performance situation, but do not increase the supporting capacity of structure." generally; preventive maintenance is exactly in fact early stage defensive maintenance; be generally comprehensive, overall; its effect is by some preposition measure methods; make road and the inside and outside disease hidden danger of structure and unfavorable conditions thereof be curbed, improve; to ensure that it is under normal operation condition, realize or extend design service life.
At present, the preventive maintenance used both at home and abroad sums up and mainly contains crack joint filling, surperficial sealing, thin overlay three types.
