作为济南市政道路建设的核心载体，沥青砼（沥青混凝土）的施工与养护正在迎来一场以“绿色、智慧”为底色的深刻变革。在双碳战略的指引下，济南的沥青砼工程不再仅仅追求路面的平整与坚固，更将环保降碳与精细化管理融入了施工的每一个环节。

As the core carrier of Jinan's municipal road construction, the construction and maintenance of asphalt concrete (asphalt concrete) are undergoing a profound transformation with "green and smart" as its foundation. Under the guidance of the dual carbon strategy, the asphalt concrete project in Jinan no longer only pursues the smoothness and solidity of the road surface, but also integrates environmental protection, carbon reduction, and refined management into every aspect of construction.

在绿色低碳方面，济南大力推广环保型沥青砼与再生工艺。例如，在经十路等主干道的养护中，全面采用了沥青路面就地热再生技术，实现了原路面材料100%的回收利用，综合节能降碳达70%以上。同时，环保稳定型橡胶沥青玛蹄脂碎石混合料（ARSMA-13）等新材料也被广泛应用于急弯、陡坡路段，这不仅消耗了废旧轮胎，实现了资源的循环利用，还能有效降低行车噪声3至8分贝。

In terms of green and low-carbon, Jinan vigorously promotes environmentally friendly asphalt concrete and recycled technology. For example, in the maintenance of main roads such as Jingshi Road, asphalt pavement in-situ thermal regeneration technology has been fully adopted, achieving 100% recycling of raw pavement materials and comprehensive energy conservation and carbon reduction of over 70%. At the same time, new materials such as environmentally friendly and stable rubber asphalt mastic crushed stone mixture (ARSMA-13) have also been widely used in sharp turns and steep slopes. This not only consumes waste tires and achieves resource recycling, but also effectively reduces driving noise by 3 to 8 decibels.

在智慧施工方面，济南依托“智慧工地1+7体系”，将沥青砼的施工推向了数字化管理的新高度。通过引入智能温度监测系统与数字化辅助摊铺碾压系统，施工团队能够实时监控混合料的温度与平整度，将误差控制在毫米级。此外，配合“夜间封闭施工+分段压实”的模式，不仅保障了施工质量，还最大程度地减少了对市民通勤的影响。从新材料的研发到智慧工地的落地，济南沥青砼工程正以精益求精的态度，为市民打造更加便捷、舒适、绿色的“都市走廊”。

In terms of smart construction, Jinan relies on the "Smart Construction Site 1+7 System" to push the construction of asphalt concrete to a new height of digital management. By introducing an intelligent temperature monitoring system and a digital assisted paving and rolling system, the construction team can monitor the temperature and flatness of the mixture in real time, and control the error within millimeters. In addition, in conjunction with the "nighttime closed construction+segmented compaction" mode, not only does it ensure construction quality, but it also minimizes the impact on citizens' commuting to the greatest extent possible. From the research and development of new materials to the implementation of smart construction sites, Jinan Asphalt Concrete Engineering is striving for excellence to create a more convenient, comfortable, and green "urban corridor" for citizens.
