公路交通是社會(huì)發(fā)展和國防的重要保障。截2023年末，我國公路總里程已達(dá)到544萬。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(shí)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)入養(yǎng)護(hù)時(shí)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(chǎng)需求的持續(xù)增長，各類養(yǎng)護(hù)工程對(duì)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.

　　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。隨著養(yǎng)護(hù)時(shí)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。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(dòng)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(jí)換代?？焖侔l(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(duì)環(huán)境的影響也不容忽視。隨著逐步實(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(dòng)，已成為發(fā)展趨勢(shì)。

　　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 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(dòng)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.

　　The application of circular economy and environmentally friendly recycling technologies and equipment supports the recycling of road materials. The national "14th Five Year Plan" mentions achieving sustainable development through green maintenance projects and the use of materials, and puts forward higher requirements for the energy-saving and environmental protection performance of maintenance equipment. The emissions of maintenance equipment itself should be gradually reduced, and the chassis of freight vehicles that do not meet emission standards should be resolutely eliminated. The existing fuel powered vehicles should gradually transition to electrification. With the new electric driven maintenance equipment as the traction and the revision and supplement of highway maintenance machinery and new material standards as the driving force, standardize product series and models, increase environmental protection and efficiency requirements, improve the progressiveness, leading and innovative nature of products, and improve the concentration of maintenance machinery products, so as to change the current situation of small number of products, wide range, many enterprises, low concentration and lack of some standards.

　　With the accumulation of technology and the growth of market demand, the proportion of domestically produced maintenance equipment is gradually increasing. This not only enhances the competitiveness of domestic industries, but also reduces dependence on imported equipment. Policy support for innovative research and development, strengthening the development of independent intellectual property equipment, and increasing the market share of domestic equipment.

　　綜合管理 現(xiàn)階段由于公路管養(yǎng)具有分段的特點(diǎn)，每段都需要自備全套公路養(yǎng)護(hù)裝備，導(dǎo)致裝備利用率低，綜合管理可統(tǒng)一分配裝備資源，提高裝備利用率。

　　At present, due to the segmented nature of highway management and maintenance, each section requires a complete set of highway maintenance equipment, resulting in low equipment utilization. Comprehensive management can allocate equipment resources uniformly and improve equipment utilization.
