Beiyang Line Rehabilitation and Maintenance Project in Chaoyang Completes Test Section Inspection; Technology Empowers a Solid Road Safety Defense

On October 12, 2026, the road-marking rehabilitation and maintenance project on the Fangshen-to-Mengguying Bridge section of the Beiyang Line in Chaoyang reached a key milestone -- the on-site quality inspection of the test section (K28+600-K28+800) was successfully completed. This phase achievement is not only a comprehensive health check of the prior construction techniques but also a crucial step in establishing quality standards and accumulating key data for the subsequent large-scale construction along the entire line, marking that this key people-livelihood transportation project has entered a new phase of refined management and control.

As an important transportation link connecting Fangshen and Mengguying Bridge, the Beiyang Line has long borne heavy transportation traffic along the route. Affected by long-term loading and natural wear, some sections have developed problems such as pavement damage and aging road markings, urgently requiring scientific and systematic rehabilitation and upgrading so as to ensure vehicle driving safety.

This inspection is not merely routine quality acceptance but also a verification and optimization of construction technique parameters. The on-site manager explained that to control construction quality along the entire line, the project set up a 200-meter road-marking test section (K28+600-K28+800). The test section was established to verify the rationality and scientific validity of the mix proportion design and the compatibility of mechanical equipment, to check construction technique parameters and test the comprehensive performance of the markings, and to provide a reliable technical basis for the subsequent large-scale standardized construction. This test-section inspection strictly followed the Standard for Quality Inspection and Evaluation of Highway Engineering, focusing on core indicators such as the retroreflection coefficient of pavement markings, marking thickness, and asphalt pavement evenness, carrying out comprehensive technical testing and evaluation. The inspection team applied a working mechanism of multi-point sampling, dynamic analysis and real-time feedback. Through high-density point-based inspection of the section from K28+600 to K28+800, detailed and reliable first-hand measured data were collected, providing a scientific basis and parameter support for subsequent construction.

The inspection data show that the pavement markings on this section feature smooth alignment and neat edges, with thickness uniformity controlled within a very small margin of error. These detailed data provide solid parameter support for subsequent large-scale construction, avoiding material waste or quality risks that blind construction might cause. In particular, in response to the significant impact of the large day-night temperature difference and increasing wind in autumn on the cooling rate of marking materials, the technical team relied on real-time monitoring data to implement fine dynamic control of construction speed and material heating temperature, integrating a perfection-seeking craftsman spirit into the entire process of modern transportation maintenance. By pioneering and trialing through the test section, seasonal construction difficulties were resolved in advance and the optimal construction control plan was determined, effectively avoiding problems of reduced adhesion or degraded retroreflection caused by overly rapid cooling. The steady progress of the Beiyang Line road-marking rehabilitation and maintenance project not only effectively improves regional traffic capacity and road service levels but also injects strong momentum into economic exchange and development along the route.

Trees line the route from Fangshen to Mengguying Bridge; the autumn scenery, though beautiful, also poses certain challenges to driving safety. High-quality road markings are like the eyes of the road and are key facilities for ensuring safe passage. The successful conclusion of this test-section inspection, controlling quality with data and consolidating the foundation with technique, has provided a replicable and promotable technical template for subsequent large-scale construction. Next, the project team will fully extend the mature technique standards formed in the test section to construction along the entire line, advancing the Beiyang Line road-marking rehabilitation and maintenance project at a high standard, striving to build a safe, comfortable, durable and reliable trunk highway, upgrading the quality of the local road network, adding a new and striking landmark to the Four Good rural road construction of Chaoyang, and earnestly supporting the implementation of the rural revitalization strategy.

We have always upheld the quality pursuit of building one project and erecting one monument, committed to creating a durable, safe and comfortable transportation environment and serving local economic and social development. In the days to come, a smooth, safe and beautiful Beiyang Line will become yet another striking transportation landmark on the land of Chaoyang.
