China is a kind very distinctive floor is phyletic, wear-resisting, compression, moistureproof, fire prevention, floor of its real wood of physical function excel, floor of real wood of tensile strength prep above and shrinkage under real wood floor, accordingly after laid not the arch since not craze, screwy, changeless form. Ferial in, our choose and buy wants to notice when wood floor, do not want the wood floor with not clear grain of choose and buy.
As we have learned, high grade wood floor is 3 years of above unripe wood refines and become. When choosing wood floor board, want to use weight of weigh in hand of hand weigh in hand, choose the wood floor board with heavier weight. The wood floor board with lighter weight is made with the tender wood that is born to two years normally, tender wood did not become a useful person, density small, wood is qualitative tenderer, stability and the compressive strength that defy a turn is not very good. The wood that 3 years above gives birth to criterion density big, stability is good, more strong and durable.
The new old light of flooring values wood the capacity is insufficient still, observe its grain even, if grain is punch-drunk, the wood that shows this wood floor is not fresh, it is datedder wood.
Rate of good wear-resisting of wood floor surface is higher. wood floor is to use normally inferior smooth wear-resisting lacquer, when choosing wood floor board, usable sandy soil makes a round trip in wood floor surface burnish ten, if wood floor does not have apparent change, state its wearability is better. Because wood floor is structure of plant crude fibre, hardness tall, density is big, so its heat conducts function, fight be out of shape function compares other and wooden floor better, optimum still the floor board that makes heating of the heat of the earth's interior.
Precision of wood floor treatment is very important also. 10 wood floors of the left and right sides can be taken arbitrarily when choosing, put on level off ground, the floor spells the floor with the orderly without large crack, appearance, structure is stable wood good for quality floor after closing. Additional, after wood floor passes particular 2 char technology, the nutrient such as cent of the bug egg in wood, will adipose, candy, protein is all after char, not only waterproof properties rises greatly, also put an end to problem of bug eat by moth at the same time.
The expert reminds say, wood floor is being used daily in, should avoid good thing to bump, edge tool cut, metal grinds etc. When cleanness, application is so pigheaded that application drier mop wipes. If the condition allows, two hit floor

Cork floor is after smashing cork into grain shape, the course reduces the floor board that bake is machined and becomes. The pyramid top that cork floor is called to be floor consumes . Have environmental protection sex, sound insulation sex more quite with real wood floor, moistureproof effect also is met betterer, cork floor flexibility is admirable, bring a person admirable crural sense. Although the old person is mixed,child trip also won't feel too aching in the ground.
Of course the value of cork floor is relative also taller, the price of homebred cork floor on the market is in probably every square metre 220 to 500 between, and of the entrance be in every square metre 700 the left and right sides, installing so process and many attention wants in be being used daily. In installing a process: Before installation even burnish ground planishs upper and clear bulgy part, eradicate the ground to become loose reach attachment; to do an aspiration first, sweep clean grey broken bits first, only area floating dust is inhaled with cleaner after, if take water burnish floor, want airing ground; to give floor the reverse side to blow glue of special floor board equably first, blow the park after glue 3 hours to be able to be used.
After that is using period of time Cork floor How should maintain again? Use 3, specific place is like to have after 5 years wear away, OK and local use make up for, put on coating afresh in local office namely, its method is very simple, use sand paper burnish gently in gall, cleared the dirty content on its face, next dry soft cloth wipes reoccupy clean gently, recoat makes coating, or in local office Fu sticks polyester film. To the cork floor that the surface brushs paint its maintain like be the same as real wood floor, it is good that average half an year hits floor wax. The surface has what the cork floor of colophony wear-resisting layer is the same as compound floor to nurse euqally simple. Prevent to heat up harm. Avoid by all means spends isotherm of hot water cup taller article to be put on the floor directly, lest iron bad surface paint film. Should prevent the sun as far as possible at the same time long point-blank floor, lest paint film by ultraviolet ray after long-term and intense illuminate, premature and weather-shack with ageing. Floor installation just can put furniture to the floor after 24 hours, 24 personnel decreases to be in what its go up to ambulate as far as possible in the hour. Leave home when going out, ask you to close good window, door especially faucet, lest water of rainwater, drop immerses floor.
A contractor in the US state of California is using skid steer loaders from Volvo CE to help in its line painting operations. The machines are being used to carry out major road marking projects in Southern California. The first machine bought by the firm has been used on the I-5 highway. Driving along the centre double line,sealing an asphalt driveway the skid steer loader is used to remove the reflective pavement markers from the asphalt and pop them into the 1.5m bucket. To boost performance, contractor Payco's industrial team developed a modification to the skid steer loader with a plate welded to the front bucket edge. As a result, the MC115C removes the reflectors efficiently at high speeds.
The machine has proven itself tough enough to cope with the shock of popping markers from the pavement. And satisfied with the skid steer loader’s performance,vibratory roller rental rates Payco recently added a second Volvo MC115C to the fleet to grind off thermoplastic striping from roadways during relining projects.
As we all know, asphalt pavement in the long-term repeated load and the role of natural light, inevitably there will be pit, bag package, net crack, subsidence as the representative of the various diseases. Because sometimes design, selection and construction quality of the wishful, more quickly the frequency of the occurrence of the disease. If these diseases are not repaired in time to restore the basic functions of the road, not only will affect the traffic flow, but also to accelerate the expansion of the disease, greatly improving the cost of repair works.

The Principle and Advantages and Disadvantages of Existing Asphalt Pavement Repair
Fujian Province Highway Maintenance Engineering Co., Ltd. to undertake Fujian Province, 2700 km highway maintenance tasks. Pavement pit repair task is mainly composed of 11 early asphalt pavement integrated maintenance vehicles to complete. The car on the asphalt pavement heating method for the heat radiation heating. The principle of heating: liquid liquefied gas after vaporization in the bottom of the heating wall to fully burn, heat through the refractory bricks blowing to the ground, intermittent heating, layers of penetration. This type of heating is actually a visible light in the pavement, because its conduction and convection accounted for a large proportion of radiation heat is small, easy to make the road was scorched or oxidized. It is not conducive to the recycling of asphalt mixture. The advantages of the thermal radiation heating method are: heating wall heat storage capacity, radiation temperature is high, thus ensuring sufficient radiation energy. Refractory brick work, the temperature reached more than 1000 ℃, the surface of a red, easy ignition, and the temperature in the work area more uniform. The main drawback is that, despite the use of intermittent heating, it is not easy to control the surface temperature of the heated pavement. Because a large number of visible radiation is very concentrated, energy radiation fluctuations, the peak temperature of the road again and again, not easy to balance. Refractory bricks have lower strength, higher cost, continuous high temperature use and easy to damage after vibration, increase the use of cost. Refractory brick replacement professionals and professional tools, maintenance is very convenient.

From the storage silo to the unloading car on the loading, 3 times loading, the first by the front of the car, the second by the rear of the car, the third loading the middle of the compartment to prevent the thickness of aggregate separation.
At the beginning of paving, at least five cars in front of waiting for discharge, to ensure the continuity of paving and road surface roughness. At the same time require the transport vehicle compartment floor coated with thin layer to prevent asphalt bonding of the isolation layer or anti-blocking agent. Paving the process of transport truck paver 100 ~ 300mm before the stop, waiting for the gap, pushed forward by the paver began to slowly discharge, to avoid impact paver.
Due to mixing field from the paving site distance is different, transport cargo vehicles must be covered with sheet insulation, rain, pollution.Road Repair Machines
The paving machine starts with three pieces of wood, such as the thickness of the concrete, as well as the thickness of the asphalt concrete compaction thickness, and the ignition screed so that the temperature can reach more than 100 ∀. Paver must be 1 ~ 3m / min speed, uniform, continuous uninterrupted paving, midway can not be variable or downtime to wait for the phenomenon, to prevent the impact of road surface roughness.
Asphalt mixture paving the spread of the temperature shall not be lower than the specified temperature, the paving the loose pile coefficient can be determined according to the test stand. Before paving, do asphalt sticky layer of inspection and cleaning: the surface of the surface after the milling of floating mineral materials, surface debris clean.
Milling Roadway dust removal equipment should use high-power air compressor dust blowing dust, so that the road cleaning dust quickly blown to the progress of the follow-up process to ensure clean and clean. The use of high-pressure air to the final blow to the milling slot to bring quality protection. And should try to avoid the spill of diesel, damage to the road, transport trucks and tools can not be used to clean the strict control of the asphalt mixture of various parts of the temperature, is conducive to ensuring the quality of asphalt concrete pavement construction. The factory temperature is higher than the specified temperature, paving less than the specified temperature of the asphalt mixture to be abolished. Asphalt concrete paving, should follow the rolling, control a good rolling times, and can not overpressure. Pavement asphalt concrete surface should be more static compaction, less vibration compaction, especially the milling side of the groove, because the vibration of the exciting force will be the edge of the original slab groove, resulting in paving because there is no solid wall Role and soon damaged. Vibration compaction is only 1 to 2 times after static pressure. Should be carefully dealt with vertical and horizontal joints and construction joints, to ensure that the new pavement and the original layer of dense joints, flat. It is forbidden to have a roller on a completed or rolling section
