2020年12月21日,国务院新闻办公室发布《新时代的中国能源发展》白皮书,清晰勾勒了我国在2060年前实现碳中和的"基本路线图"。而在公路建设领域,我国公路及城市道路路面类型大多为沥青路面,沥青路面在新建、改扩建中所面临的能耗巨大、污染严重、旧料回收等环保问题日渐凸显,引发的环境问题不容小觑。本文通过将传统沥青路面的施工工艺流程与低碳、节能等绿色发展理念进行综合分析,阐明了其发展中所面临的诸多环保问题,并利用SWOT分析法对环保沥青的发展态势进行界定,提出了环保沥青材料在不同内外部环境下发展的应对举措,梳理思考了基于传统工法下几种环保沥青路面的发展路线,借以为科技创新引领绿色公路建设的新发展阶段提供一定参考。 相似文献

在双碳目标的指引下,低碳化乃至零碳化成为交通隧道工程发展的必由之路,而数字化转型为此带来了机遇与挑战。智慧基础设施服务系统可从信息的采集、传输、处理、分析、表达与服务全过程为交通隧道工程的低碳化发展提供强有力的数字底座,大数据、云计算、区块链、人工智能等前沿技术可为交通隧道工程的全面勘察、动态设计、智能建造与高效运维注入新的发展活力。目前关于低碳隧道的相关研究还处于起步阶段,相关标准体系尚未形成,低碳与零碳隧道的发展目标、数字化赋能的具体对象与实现路径尚未明晰,相应的顶层设计理论也亟待深入研究。文章初步分析了交通隧道工程的碳排放特征,回顾了当下数字化技术在隧道工程全寿命期的成功应用,并在此基础上进一步梳理、展望了数字化技术在低碳隧道中的应用前景。未来,低碳隧道的发展应把握好后发优势,加强数字化与绿色低碳理念的深度融合,在全面提升交通隧道工程数字化水平的同时,推进交通隧道行业碳中和目标的稳步实现。 相似文献

The rate and manner in which transport infrastructure (e.g. roads, railway tracks, airports) is deployed, will play an important role in determining energy demand, greenhouse gas emissions and the economic impact of the transport sector. This paper describes an exercise where the costs of infrastructure deployment for the transport sector have been incorporated into the IMACLIM-R Global E3 IAM. In addition to adding these costs, the modelling of the criteria for the deployment of infrastructure for roads has also been improved. It is found that this model recalibration results in a more accurate baseline as compared to historically observed data (2001–2013) for investments in energy demand, road infrastructure, and passenger kilometers travelled. Regarding macroeconomic effects, it is found that the imposition of a carbon emission trajectory to 2100 cause GDP to decrease relative to the newly calibrated baseline – this is a standard IAM result. However, when the deployment of infrastructure for roads and air travel is further constrained, the GDP loss is less than with a fixed carbon emission trajectory only. This is because early restriction of infrastructure for roads and air travel allows an expansion of public transport infrastructure which is adequate to meet low-carbon transport service demand whereas when less public transport infrastructure is available, more costly mitigation investments must be made in other parts of the economy. This suggests that restricting infrastructure deployment as a complementary policy to carbon pricing, lowers the cost of mitigation. 相似文献

Nearly all countries are seriously short of revenues for investment and maintenance of roads. Improving utilization of the existing road budget has helped to narrow, but not eliminate, this financing gap. Requests for additional resources from the government's budget have fallen on deaf ears, because the road sector has grown too large to be fully-financed through general tax revenues. Government tax systems were not designed to finance major economic sectors like roads. Faced with an acute shortage of funds, many road agencies have introduced tolls on high-volume roads and have invited the private sector to build and operate such roads under concession agreements. Although this has narrowed the financing gap, tolling is only economic on a small part of the road network. Tolls have thus had a relatively small impact on the financing gap. Against this background, and mindful of the fact that roads are now 'big business' on the scale of the Fortune Global 500, a growing number of countries have started to 'bring roads into the market place, put them on a fee-for-service basis and manage them like a business.' The fee-for-service concept, though superficially like the user-pay principle and the associated road funds which became popular during the 1950s, differs from user-pay in a number of important respects. The key differences are that: (i) only road user charges go into the road fund (i.e., there are no earmarked taxes); (ii) the fund is managed by a representative board with half or more members representing road users and the business community; (iii) members are nominated by the constituencies they represent and there is an independent chairperson; (iv) financing arrangements are designed to ensure that money is not diverted from other sectors; (v) funds are managed pro-actively by a small secretariat; (vi) there are published financial regulations governing the way funds are managed; (vii) charges are adjusted regularly to meet agreed expenditure targets; and (viii) there are regular technical and financial audits. Other important characteristics are that most commercially managed road funds are managed through a separate road fund administration, funds are channeled to all roads (sometimes even to unclassified roads) and they are introduced as part of a wider agenda to commercialize road management. Some of these road funds have been set up as road public utilities under a board with powers to set their own tariffs. 相似文献
