Abstract
The invention discloses a kind of road construction methods, include the following steps：(1) unwrapping wire is carried out with total station survey setting-out and spirit level, delimit road construction scope；(2) architecture sediment is filled at pot hole, it is paved with bull-dozer, smooth backfill, it is rolled again with road roller backfill, complete the laying of road foundation, the architecture sediment is made of queen closer, concrete block, stone and tile fragment, the queen closer, concrete block, stone and tile fragment be broken crusher machine to grain size be 20 25cm；(3) surface of road foundation is cleared up；(4) the uniform spread rubber asphalt on road foundation, forms one layer of rubber asphalt layer, and rubber asphalt dosage is：1.8 2.0kg/m2 are laid with rubble on the rubber asphalt layer again afterwards, and rubble are compacted to form metalling, the spread emulsified asphalt layer on metalling, and the dosage of the emulsified asphalt is：0.5‑0.7kg/m2.Road construction method in the present invention is it is possible to prevente effectively from highway occurs collapsing and phenomena such as crack.
Description
Technical field
The present invention relates to technical field of road construction, and in particular to a kind of road construction method.
Background technology
With the rapid development of Chinese national economy, country is also increasing to the investment of infrastructure construction.Highway is built
It is the important channel for promoting integration of urban and rural economics construction if the development of cause.But with being continuously increased for highway construction mileage,
The quality problems of road construction are increasingly becoming focus.For example, road surface is led because material internal voidage is excessive, infiltration coefficient is bigger than normal
Cause pavement spread, compacting difficult；For highway once coming into operation, the high temperature and rainy season road surface after being open to traffic is susceptible to crack, hole
Low-lying area and other issues.
The content of the invention
It is an object of the invention to provide a kind of road construction methods, can effectively solve to be carried in background technology
To the technical issues of.
To achieve the above object, the present invention provides following technical solution：
A kind of road construction method, includes the following steps：
(1) unwrapping wire is carried out with total station survey setting-out and spirit level, delimit road construction scope；
(2) architecture sediment is filled at pot hole, is paved with bull-dozer, smooth backfill, then backfilled and ground with road roller
Pressure, completes the laying of road foundation, the architecture sediment is made of queen closer, concrete block, stone and tile fragment, the brickbat
Block, concrete block, stone and tile fragment be broken crusher machine to grain size be 20-25cm；
(3) surface of road foundation is cleared up；
(4) the uniform spread rubber asphalt on road foundation, forms one layer of rubber asphalt layer, and rubber asphalt dosage is：
1.8-2.0kg/m2 is laid with rubble on the rubber asphalt layer again afterwards, and rubble is compacted to form metalling, in metalling
Upper spread emulsified asphalt layer, the dosage of the emulsified asphalt are：0.5-0.7kg/m2；
(5) covered rearing with plastic film emulsified asphalt layer, then covering and heat insulating layer on the plastic film are used, after covering 12 days -14 days,
Plastic film is removed, the insulating layer is straw and thickness is 6cm~8cm.
Preferably, also added with slag and slag in the architecture sediment, the mixture of slag and slag is denoted as batch mixing one,
Mass ratio between batch mixing one and architecture sediment is 1：7.
Preferably, the queen closer, concrete block, stone and tile fragment be broken crusher machine to grain size be 20-22cm.
Preferably, the metalling from bottom to top not Wei the first metalling and the second metalling, first metalling
Grain size is 14mm-16mm, and the grain size of second metalling is 8mm-12mm.
Compared with prior art, the beneficial effects of the invention are as follows：
The present invention is equipped with rubber asphalt, and then improves viscous stickiness, wearability and the water proofing property of road, can be effective
Upper road surface is avoided aggregate loss or whole the phenomenon that coming off occur, at the same time, substantial amounts of moisture is also prevented from and oozes
Enter the bottom of highway, highway is avoided to be collapsed caused by due to infiltration and phenomena such as crack.
