Having been one of the first Chinese companies tasked with developing highway systems at our founding in 1978, we know a thing or two about delivering highways that connect communities and opportunities.
From the outset of our business in 1978, connecting people through high quality road systems has been major focus of our company. With over 40 years' experience in the field and having been responsible for some of the most important road networks in the country, we know what it takes to deliver on these kinds of projects.
We are also proud to be recognised leader's in research & development of this field, with two top national research centres in advanced road materials and bridge safety. Our National Engineering Lab for Advanced Materials is constantly working to provide durable, eco-friendly and functional new road materials that deliver on both quality and performance.
Meanwhile, our Bridge Safety Lab conducts research into issue detection and management of large scale bridges, health consultation, state evaluation, defect repairing and function improvement technologies. This research is fundamental to preserving the longevity of large scale bridges and increasing their functional life span.
