The Development of the Conrvation of Asphalt
Pavement
Asphalt pavement in the u of the process, constantly subject to the role of repeated traffic loads, climate impact and asphalt pavement materials, physical and chemical changes, over time, will have a pit, crack, swarming spore, subsidence, while eating, Ma surface , peeling and loo a variety of damage, if not repaired, the damage will be expanded rapidly and affect the normal passage of vehicles, and may lead to a greater degree of damage. Asphalt Pavement Maintenance vehicle is dedicated to timely repair the damage part of the special vehicles. Shown as an ordinary car Asphalt Pavement Maintenance.
1 Classification and function
鄙视英文>あいりみくAccording to the nature of road paving materials, road vehicles can be divided into a comprehensive conrvation Asphalt Pavement Maintenance trucks and cement trucks Pavement Maintenance two categories, this book introduces the Asphalt Pavement Maintenance Truck. Asphalt Pavement Maintenance vehicles is divided into trailers by the way traffic and two types of lf-propelled.
Towed Asphalt Pavement Maintenance vehicles are a variety of equipment and devices will be installed on the trailer chassis, the general u of lf-powered engine output range of devices and equipment, from a car or tractor to the construction of ctions of the conrvation work carried out.
Self-Asphalt Pavement Maintenance vehicles are a variety of equipment and devices will be installed on the vehicle chassis or exclusive as the lf-end, removed from the chassis host two types of motivation and lf-engines. At prent, the production of integrated conrvation of the asphalt is the most lf-propelled vehicles of.
Bad on the technical level of the road, the quality and quantity of the different lection of different types of Asphalt Pavement Maintenance vehicles. High-grade随便看看英语怎么说
highway mileage in the asphalt pavement of more than 300km for the u of large-scale conrvation of lf-propelled vehicles; medium-sized lf-propelled vehicle for the conrvation of 200-300km of high-grade asphalt pavement minor repairs, maintenance; 200km below the asphalt pavement for the u of high-grade lf-small conrvation of vehicles. Daily Maintenance of Asphalt Pavement in general for the u of small lf-propelled or towed vehicle conrvation.
Asphalt Pavement Maintenance for road vehicles in addition to day-to-day tasks of conrvation, but
also other facilities can be ud for highway maintenance, traffic engineering facilities, such as spraying and cleaning, snow removal, cleaning the road surface, cut away weeds, spraying, planting and trimming trees.
2 multi-purpo road vehicles at home and abroad overview of conrvation and development trends
2.1 Overview abroad
四级成绩多少分过Asphalt Pavement Maintenance Machinery abroad have been a hundred years the history of high-grade highway for minor repairs of the asphalt pavement of the integrated conrvation of mechanical operations have 60-a 70-year history. Them according to the functions and operations can be divided into the following.
(1)With infrared heating function Pavement Maintenance car models for the United States on behalf of Thermal Power Corporation (Thermal PowerCo.) King of the road. Its most prominent feature of the old material can be recycled in situ, thereby bring about considerable savings in asphalt mixture, in favor of environmental protection and conrvation of energy. At the same time, as a result of mixture with the original road is a natural joints combination of old and new roads clo, you can ext
end the life of the new road. The model applicable to shallow holes, cracks, cracks and other damage to the handling of the asphalt pavement. The vehicle is equipped with hot-mix boxes, asphalt tanks and sprinkler systems, and infrared propane gas heater, compaction tools, waste tanks.
(2)Mixture with hot boxes and broken pavement compaction tool Pavement Maintenance car model is the United States on behalf of Akzo Nobel company TP4-bad integrated conrvation vehicles. The more the number of vehicles in foreign countries, usually with the following equipment: 7t heat insulation material boxes, spiral out of feeder, asphalt spraying device, and vibration-ho ram broken. The models applied to patch small pit operation.
(3)Jet car repair on behalf of the conrvation model is the official music of the high road repair company cars, the largest high-pressure injection is characterized by the adoption of the ways in which a different charge of the emulsified asphalt and aggregate to be mixed and sprayed into the pits to deal with in to achieve the purpo of maintenance and repair of the road the car can be opened to traffic immediately. The model applies to a smaller stream of pits of repair work.
香港中文大学排名(4)Comprehensive conrvation repair work on behalf of car models produced LeeBoy the United St
ates 1200-S-type of asphalt pavement repair vehicle integrated. It has a miller, spraying asphalt, paving and other features, equipped with a milling machine, paving equipment, asphalt me, hydraulic sprinkler system and asphalt-ho. The model applies to a small area of repair operations.
2.2 Overview of domestic
With highway construction in China's rapid development, in particular, the traffic mileage of highway continues to increa, the domestic machinery of the road more and more emphasis on conrvation. The 20th century, some of the 80's started a lot of companies have developed products to market. On the integrated conrvation of vehicles, the domestic current owners have developed the following types of conrvation.
(1)TP4-bad Pavement Maintenance car full hydraulic control, with storage, crushing, compaction equipment and other road maintenance equipment Yung Road, Maung. It is the introduction of the United States in Xi’an building auromatically • Akzo Nobel technology, enterpri development by the domestic products.
ipo是什么的缩写(2)Regeneration asphalt mixture characterized by the conrvation of cars expected to regeneration with the old, old asphalt can generally through the addition of some new materials and renewable so
urces of new agents is expected to achieve the old shop, with a broken, regeneration, compaction equipment and other attachments. However, this equipment can not be ud for high-grade renewable materials for road maintenance, the u of occasions by a lot of restrictions.
(3)Heating wall with regeneration in situ conrvation of vehicles on the road to soften it, harrow, Tim the new material, first-class one-stop operating pressure, energy saving, environmental protection. Both drive electric drive, there are hydraulic driven. Becau development time is too short, the reliability of the product there are still
large deficiencies. In addition, becau the device can only u the new asphalt mixture, there is also a conrvation site is not expected to work without problems. 2.3 Asphalt Pavement Maintenance of our direction of development of car拳头产品
Conrvation equipment available in the planned economy era developed. With highway construction in China's rapid development. China's existing mechanisms for road maintenance is no longer suited to this situation, the state departments are to develop new policy and regulatory road maintenance to adapt to this change, it is foreeable that this policy applies to the new norms of conrvation equipment market will be favored .

niton沥青路面的养护发展
沥青路面在使用过程中，不断承受行车载荷的反复作用、气候的影响和沥青路面材料的物理化学变化，随着时间的推移，将产生坑槽、裂缝、涌包、沉陷、啃边、麻面、脱皮和松散等各种损坏，如不及时修补，这些损坏将迅速扩大，影响车辆的正常通行，并可能造成更大程度的损害。沥青路面综合养护车就是专门用于及时修补路面损害部分的专用车辆。所示为普通沥青路面综合养护车。1、分类及功用
陪伴英语根据路面铺筑材料的性质，路面综合养护车可分为沥青路面综合养护车和水泥路面综合养护车两类，本书主要介绍沥青路面养护车。沥青路面综合养护车按行驶方式分为拖式和自行式两类。
拖式沥青路面综合养护车是将各种设备和装置安装于拖挂底盘，一般用自备发动机输出动力驱动各种装置和机具，由汽车或拖拉机牵引到施工路段进行养护作业。
自行式沥青路面综合养护车是将各种设备和装置安装于汽车底盘或专用的自行式底般，分从底盘主机取出动力和自备发动机两种。目前生产的沥青综合养护车大部分是自行式的。
usually怎么读
依据公路技术等级、质量状况和数量的不同，选用不同类型的沥青路面综合养护车。高等级沥青路面
公路里程在300km以上的，适合使用自行式大型养护车；自行式中型养护车适用于200—300km的高等级沥青路面小修、养护；200km以下的高等级沥青路面适合使用自行式小型养护车。一般沥青路面日常养护适合使用小型自行式或拖式养护车。
沥青路面综合养护车除用于路面日常养护任务外，也可用于公路其他设施的维护，如交通工程设施的喷涂和清洗、除雪、清扫路面、剪除杂草、喷洒药剂，栽植和修整花草树木等。
2、多功能路面养护车国内外概况及发展趋势
2．1国外概况
国外沥青路面养护机械已有百年的历史，用于高等级公路的沥青路面小修作业的综合养护机械也有60一70年的历史。它们按功能和作业方式可分为以下几
