公路交通是社會發(fā)展和國防安全的重要保障。截至2023年末，我國公路總里程已達(dá)到544萬公里。隨著我國公路網(wǎng)絡(luò)建設(shè)日漸完善，未來公路建設(shè)強(qiáng)度將逐步下降，養(yǎng)護(hù)需求將快速上升。

　　Highway transportation is an important guarantee for social development and national defense security. As of the end of 2023, the total length of highways in China has reached 5.44 million kilometers. With the gradual improvement of China's highway network construction, the intensity of highway construction will gradually decrease in the future, and the demand for maintenance will rapidly increase.

　　新時代公路養(yǎng)護(hù)技術(shù)與裝備的發(fā)展需求

　　The development needs of highway maintenance technology and equipment in the new era

　　根據(jù)交通運(yùn)輸部數(shù)據(jù)，我國公路養(yǎng)護(hù)里程逐年增長，養(yǎng)護(hù)比例高達(dá)99.9%。

　　According to data from the Ministry of Transport, the maintenance mileage of highways in China has been increasing year by year, with a maintenance ratio of up to 99.9%.

　　養(yǎng)護(hù)工程需求

　　Maintenance engineering requirements

　　我國公路已進(jìn)入全面養(yǎng)護(hù)時代，需要綜合維護(hù)路面、橋梁、隧道等各類設(shè)施，公路養(yǎng)護(hù)財(cái)政支出每年約為1.2萬億元。隨著公路養(yǎng)護(hù)市場需求的持續(xù)增長，各類養(yǎng)護(hù)工程對公路養(yǎng)護(hù)裝備的需求也將隨之增長。

　　China's highways have entered the era of comprehensive maintenance, requiring comprehensive maintenance of various facilities such as road surfaces, bridges, tunnels, etc. The annual fiscal expenditure on highway maintenance is about 1.2 trillion yuan. With the continuous growth of demand in the highway maintenance market, the demand for highway maintenance equipment in various maintenance projects will also increase accordingly.

　　國家生態(tài)環(huán)境保護(hù)戰(zhàn)略需求

　　National ecological environment protection strategy needs

　　公路大中修產(chǎn)生的廢舊瀝青混合料已造成嚴(yán)重的環(huán)境污染。隨著全面養(yǎng)護(hù)時代的到來，以及全球日漸加劇的環(huán)境保護(hù)壓力，如何合理處置這些廢舊建筑材料成為亟待解決的重要課題。國家從戰(zhàn)略層面提出綠色發(fā)展要求，行業(yè)推出加快加大廢舊材料循環(huán)利用的政策措施，推動相關(guān)技術(shù)與裝備發(fā)展。

　　The waste asphalt mixture generated during the major and medium repairs of highways has caused serious environmental pollution. With the advent of the era of comprehensive maintenance and the increasing global pressure on environmental protection, how to properly dispose of these waste building materials has become an important issue that urgently needs to be addressed. The country has put forward green development requirements at the strategic level, and the industry has introduced policies and measures to accelerate and increase the recycling of waste materials, promoting the development of related technologies and equipment.

　　目前，國內(nèi)外普遍采用再生技術(shù)實(shí)現(xiàn)廢舊公路材料的循環(huán)利用，雖然已經(jīng)取得很大成效，但是還有較大發(fā)展空間，現(xiàn)有再生裝備也亟需升級換代。快速發(fā)展的養(yǎng)護(hù)需求，將使由運(yùn)輸車輛底盤改裝而來的養(yǎng)護(hù)機(jī)械裝備大量增加，其運(yùn)行排放對環(huán)境的影響也不容忽視。隨著國家逐步實(shí)現(xiàn)“雙碳”目標(biāo)，新能源技術(shù)應(yīng)運(yùn)而生。采用新能源電池、氫能源驅(qū)動，已成為發(fā)展趨勢。

　　At present, recycling technology is widely used both domestically and internationally to achieve the recycling of waste road materials. Although significant progress has been made, there is still considerable room for development, and existing recycling equipment urgently needs to be upgraded and replaced. The rapidly developing maintenance demand will lead to a significant increase in maintenance machinery and equipment modified from transport vehicle chassis, and the impact of their operational emissions on the environment cannot be ignored. As the country gradually achieves its "dual carbon" goals, new energy technologies have emerged. The adoption of new energy batteries and hydrogen energy drive has become a development trend.

　　The demand for building a modern highway maintenance system

　　加快構(gòu)建現(xiàn)代公路養(yǎng)護(hù)體系，推行養(yǎng)護(hù)決策科學(xué)化、養(yǎng)護(hù)管理制度化、養(yǎng)護(hù)工程精準(zhǔn)化、養(yǎng)護(hù)生產(chǎn)綠色化，是公路養(yǎng)護(hù)事業(yè)的發(fā)展方向，也是公路交通轉(zhuǎn)型升級、服務(wù)交通強(qiáng)國的必由之路。

　　Accelerating the construction of a modern highway maintenance system, promoting scientific maintenance decision-making, institutionalized maintenance management, precise maintenance engineering, and green maintenance production is the development direction of the highway maintenance industry, as well as the necessary path for the transformation and upgrading of highway transportation and the service of a strong transportation country.

　　現(xiàn)代公路養(yǎng)護(hù)體系要求養(yǎng)護(hù)技術(shù)綠色化，養(yǎng)護(hù)裝備智能化、系列化、多功能和配套集成化，養(yǎng)護(hù)施工節(jié)能環(huán)?！，F(xiàn)有技術(shù)與裝備很多還屬于傳統(tǒng)設(shè)計(jì)理念范疇的產(chǎn)物，與現(xiàn)代公路養(yǎng)護(hù)體系的要求尚有較大差距。

　　The modern highway maintenance system requires green maintenance technology, intelligent, serialized, multifunctional and integrated maintenance equipment, and energy-saving and environmentally friendly maintenance construction. Many existing technologies and equipment are still products of traditional design concepts, and there is still a significant gap between them and the requirements of modern highway maintenance systems.

　　因此，公路養(yǎng)護(hù)技術(shù)與裝備的更新?lián)Q代已成為構(gòu)建現(xiàn)代公路養(yǎng)護(hù)體系的重要內(nèi)容，也是深化國家交通強(qiáng)國戰(zhàn)略的迫切需求。其在加快建設(shè)交通強(qiáng)國、推動交通運(yùn)輸行業(yè)高質(zhì)量發(fā)展及服務(wù)構(gòu)建新發(fā)展格局等方面，具有促進(jìn)投資和消費(fèi)的積極作用。

　　Therefore, the upgrading of highway maintenance technology and equipment has become an important part of building a modern highway maintenance system and an urgent need to deepen the national strategy of building a strong transportation country. It plays a positive role in promoting investment and consumption in accelerating the construction of a strong transportation country, promoting high-quality development of the transportation industry, and building a new development pattern for services.

　　路面清掃車 路面清掃車用于清理路面上的灰塵、砂石及其他雜物，可保持道路清潔度，不僅提高了道路行駛的視覺美感，還降低了因路面碎屑、雜物造成車輛打滑或損傷的風(fēng)險。路面清掃車在高速公路、國省干線公路及城區(qū)道路上使用頻次較高。

　　Road sweepers are used to clean dust, sand, gravel, and other debris on the road surface, maintaining road cleanliness. They not only improve the visual aesthetics of road driving, but also reduce the risk of vehicle slippage or damage caused by road debris and debris. Road sweepers are frequently used on highways, national and provincial trunk roads, and urban roads.

　　封層車 目前使用的表面封層技術(shù)有同步碎石封層、霧封層、稀漿封層（微表處）、薄層攤鋪等。其中同步封層技術(shù)應(yīng)用最廣泛，霧封層和稀漿封層次之。同步碎石封層車采用普通載貨汽車底盤搭載專用上裝，實(shí)現(xiàn)一層瀝青和一層碎石同步撒布施工。瀝青灑布車是霧封層施工的專用裝備，是一種灑布乳化瀝青、稀釋瀝青、熱瀝青、熱改性瀝青及各種黏合劑的施工裝備。

　　The surface sealing technologies currently used by sealing vehicles include synchronous gravel sealing, mist sealing, slurry sealing (micro surface), and thin layer paving. Among them, synchronous sealing technology is the most widely used, followed by mist sealing and slurry sealing layers. The synchronous gravel sealing vehicle adopts a common cargo truck chassis equipped with a dedicated upper cover, achieving synchronous spreading construction of one layer of asphalt and one layer of gravel. Asphalt distribution truck is a specialized equipment for fog sealing layer construction, which is a construction equipment for spraying emulsified asphalt, diluted asphalt, hot asphalt, heat modified asphalt and various adhesives.

　　稀漿封層（微表處）主要用來處理道路表面裂縫、車轍和摩阻力下降等病害，以提高路面的防水性和抗滑性，改善路面平整度和行車舒適性，從而達(dá)到“返老還新”的效果。該封層裝備可廣泛應(yīng)用于普通稀漿封層、改性稀漿封層（微表處）的施工工藝中。

　　The slurry seal layer (micro surface) is mainly used to treat road surface cracks, ruts, and reduced friction, in order to improve the waterproof and anti-skid properties of the road surface, improve road smoothness and driving comfort, and achieve the effect of "returning old and new". This sealing equipment can be widely used in the construction process of ordinary slurry sealing and modified slurry sealing (micro surface).

　　公路應(yīng)急搶險裝備 公路應(yīng)急搶險裝備應(yīng)用較多的主要有高空作業(yè)車和防撞護(hù)欄安裝裝備。高空作業(yè)車是保障檢修人員作業(yè)安全的高空工作平臺，是確保交通設(shè)施正常運(yùn)行，維持交通系統(tǒng)順暢和安全運(yùn)行的關(guān)鍵裝備。防撞護(hù)欄安裝裝備專門用于安裝和維護(hù)公路上的防撞護(hù)欄，利用該裝備施工可提高作業(yè)效率和安全性。
