Description
Technical field
The utility model relates to a kind of engineering truck, particularly relates to the recovery engineering truck that a kind of hacking is handled the pavement skid resistance ability.
Background technology
Along with development and national economy, the highway in China mileage increases to be accelerated, and according to planning, will build up 12 trunk lines of national expressways of five national trunk highways running from north to south and seven running from west to east, 3.5 ten thousand kilometers of length overalls to China in 2010.Speedway is as the main body of trunk lines of national expressways, and mileage increases rapidly.Highway mileage increase the widespread demand that must cause rapidly to maintenance technology, and this on the one hand the present technological reserve of China be not enough, can't satisfy the needs of keeping road network safety, efficient, economical operation.
Highway in China accident rate height is far longer than other developed country, this be in the highway in China transport development the problem that must solve.The ascendant trend of China's traffic accident more allows of no optimist.The numeral that provides according to Public Security Department of the Ministry of Public Security shows, China's traffic accident total amount rises to 2002 770000 by 290,000 in 1986, increases by 6.3% every year; Death toll increases by 5% every year by 10.9 ten thousand people that 50,000 people in 1986 rise to 2002.The exclamation of " traffic accident is suddenly in tiger " when enjoying modern transportation, people is also often arranged.
The reason that causes road traffic accident is many-sided, and wherein very important one is exactly the deficiency of pavement skid resistance ability.If can allow the vehicle of running at high speed stop in the extremely short time, and can avoid lateral sliding, we can avoid the generation of a lot of accidents or reduce its order of severity.Find in the investigation in the past, a lot of accident-prone road sections, other condition is constant and only change pavement skid resistance condition, and traffic accident just can significantly reduce.For example Miller and Johnson (1973) show Britain M4 speedway cover the first two years and back 2 years accident investigation, work as SFC
50Bring up to 0.55 o'clock total accident rate from 0.40 and descended 45%, the dry pavement accident rate has descended 28%, and wet road surface accident rate has then descended 63%.The seriousness of wet traffic accident or wet road surface accident has directly reflected the deficiency of pavement skid resistance power.The road surface is polished under the traffic effect, pavement skid resistance power constantly decay is inevitable, but in the speedway that China has built up, there is the too fast problem of skid resistance decay, the qualification rate of SFC value had just dropped to below 20% after the highway that has was open to traffic 1 year, and the deficiency of pavement skid resistance power has caused the highway in China accident rate much larger than other developed country." life-and-death matter ", the transport solution safety problem has huge economic benefit and social benefit.
Bellding is one of common quality defect of fine solution not yet in present China expressway construction.To guarantee the road surface enough surface roughnesses (macrostructure) are arranged though China's speedway all is provided with the antiskid top layer, detect data and show, the durability wretched insufficiency of its road table macrostructure of speedway of significant proportion is arranged.No matter be many rubbles bituminous concrete, AK structure or SMA, such problem is all arranged.Distribute and the compacting sinking of coarse aggregate makes road surface glossy mirror that just become in short 1～2 year at the pitch emphasis that produces under the traffic effect, seriously influenced traffic safety and ride comfort.Therefore we can say that we also on top of do not build the key technology of rough surface and durable road crust at present.
The method of existing recovery pavement skid resistance ability has:
1. asphalt ultrathin cover: should this method be a kind of common method, advantage such as it is simple to have technology, practical, but need first milling, and then overlay, economy is poor, the close traffic time is long, generally is to be used for the maintenance works under the serious or rut serious situation at road surface breakage.
2. emulsified asphalt slurry seal: this method also is a kind of common method, and technology is simple, and is practical, and economy is relatively good, but structure durability can't reach requirement, and the time of close traffic is longer, and technology is not mature enough and stable.
3. resin material seal: advantages such as this cover has that skin coat is thin, good endurance, easy construction, antiskid effect are obvious, but involve great expense, be difficult to widespread adoption.
4. cutting: be used for cement concrete pavement more, advantage is a good endurance, but construction cost is higher, solve weak effect for fine and close smooth such microtexture problem of screed itself and the such pollution problem of oil dripping, road pavement can cause destruction to a certain degree, and therefore up to the present China is still not large-scale uses.
5. cutter impacts hair: it is to hit the road surface and make the road surface fluffing with the sintered carbide tool bit cutter that cutter impacts hair, and range of application is little, and China once set up the project in early 1990s and study machinery and cut a hole mao but do not achieve success.
6. artificial cutter hair: artificial cutter hair is manually to hit the road surface and make the road surface fluffing with chisel or sharp shaped material cutter, efficient is low, labour intensity is big, can't meet the quality requirement, the construction cost height, environment pollution is big, and the close traffic time is long, and personal safety and health are difficult to guarantee, the most original a kind of job practices that can only be applicable among a small circle, vehicle flowrate is little basically need not now.
7. jet hacking: the jet hacking also is difficult to practical application owing to the restriction of reasons such as technology and material.
8. pickling: pickling processes generally only is applicable to the oil dripping of cement concrete pavement, pollutes easily, bans use of now.
Above-mentioned many deficiencies, it is extremely urgent that development pavement skid resistance ability is recovered engineering truck.
