Technical field
The present invention relates to asphalt concrete pavement maintenance and repair association area, be specifically related to the little processing method in a kind of asphalt concrete pavement top layer.
Background technology
Asphalt concrete pavement is widely used in road surface etc. in airport runways, speedway, arterial highway, urban road, factories and mines road and field, stop, the tunnel.Under the effect of traffic load and amblent air temperature impact, asphalt concrete pavement situation and service ability will run down.For the kilter that keeps Pavement Condition and prolong its application life, adopt different maintenance measures in each different phase of life cycle, the maintenance technology of employing science becomes the Recent study focus with maintenance quality and the reduction maintenance cost that guarantees the road surface.For example in the road disease Development stage, the technology such as joint filling, joint seal, mist seal, slurry seal, little table place, cape seal, screening seal coat, rut are filled up, thin overlay, ultra-thin wearing layer, superthin layer cover start one preventive maintenance upsurge at home like rain rear spring bamboo.Yet, through application for many years, the technology such as the domestic cover of generally taking, little table place, overlay heated bitumen are limited to road elevation, durability, load-bearing, traffic pressure, cost and self can not adapt to the needs of modern urban road development to factors such as material, equipment requirement height at present, and step down from the stage of history gradually.Seek so a kind of environmental protection, quick, effect is durable, cost is relatively cheap new technology, with to occur wearing out, the bad asphalt concrete pavement of the diseases such as pitted skin, loose, cracking, infiltration, polishing in time processes, it is imperative to prolong Road Service Life.
Summary of the invention
The anti-slide performance decline that after using for many years, occurs for solving asphalt concrete pavement, the problems such as the road surface is aging, pitted skin, loose, cracking, infiltration, polishing, prolong Road Service Life, the invention provides the little processing method in a kind of asphalt concrete pavement top layer, reach fast quick-recovery function path and beautify road, and can reduce the road maintenance cost.
Purpose of the present invention is achieved through the following technical solutions:
The little processing method in a kind of asphalt concrete pavement top layer comprises following processing step:
A. the old asphalt concrete road surface of polishing;
B. the cleaning, dry pavement;
C. measure unwrapping wire, molding;
D. prepare the bituminous epoxy mortar, described bituminous epoxy mortar is that aggregate and binding material are by weight being 1:(0.3 ~ 1) mixture, described aggregate is selected from purity quartzite, diamond dust, basalt particle or the ceramic particle of particle diameter≤3mm, and described binding material is bituminous epoxy mortar bonding material;
E. mortar blade coating, spreading aggregate and compacting;
F. maintenance moulding and on-the-spot cleaning: be not less than 25 degrees centigrade at temperature, relative humidity is not more than to place under 60% the condition and guaranteed the complete curing molding of described binding material in 2 ~ 3 hours, clears up the unnecessary aggregate in road surface again.
Described polishing old asphalt concrete road surface is the degree according to pavement damage, and according to different actual conditions, selects shot-blasting machine or/and milling machine polishing old asphalt concrete road surface; Select powerful scavenging machine to remove earth, the greasy dirt on road surface.
Describedly select shot-blasting machine or/and milling machine polishing old asphalt concrete road surface makes old pavement present the dark texture of 1 ~ 2mm.
Described cleaning, dry pavement are that the road surface after selecting forest fire extinguisher and dust catcher to polishing purges dust out, rubble.
Described measurement unwrapping wire, molding are to measure unwrapping wire according to the construction area actual conditions, place template and have drawn horizon according to construction thickness, and calculate epoxy asphalt mortar, bituminous mortar use amount according to practice of construction area size.
Described mortar blade coating is that the bituminous epoxy mortar for preparing is poured in the described template, the bituminous epoxy mortar is scraped off along the described horizon that mixes up in advance with scraper plate, makes to form evenly to film without the bituminous epoxy mortar of scratch.
Described spreading aggregate is to be that the even spreading of basalt aggregate, ceramic particle or diamond dust of 0.6 ~ 1.5mm or 1 ~ 3mm is to the bituminous epoxy screed with specification.
Described compacting is gently to press aggregate with the hair roller behind the aggregate spreading, guarantees that aggregate embeds in the epoxy asphalt mortar, bituminous mortar layer.
With respect to prior art, the advantage of present technique invention:
(1) the little processing method in asphalt concrete pavement top layer of the present invention adopts the bituminous epoxy mortar as the top layer wearing layer, both solved the poor difficult problem of thin layer and former road surface bonding, greatly improve again pavement skid resistance ability, durability, and can reduce the road maintenance cost;
(2) the not obvious increase road of the little processing method in asphalt concrete pavement top layer of the present invention clear height, net weight, it is convenient to construct, and can realize Rapid-Repair to asphalt concrete pavement, improves the road efficiency of operation.
Description of drawings
Fig. 1 is process flow diagram of the present invention.
The specific embodiment
Embodiment
For a better understanding of the present invention, below in conjunction with embodiment the present invention is further described.
