我们国家的经济在飞速的发展,我们国家的公路里程在不断的升高,很多桥梁也是横空而起的。交通设施在不断的完善,人们的出行变得越来越便捷,但是我们的路桥工程还有很多的不足。在实际的路桥工程之中,公路和桥梁的质量和路基路面的质量是息息相关的,本文探究的是路桥工程之中路基和路面的施工技术问题。 The economy of our country is growing rapidly. The mileage of our country’s roads is constantly rising. Many bridges have also taken shape. Traffic facilities are constantly improving, people’s travel has become more and more convenient, but our road and bridge project there are many deficiencies. Among the actual road and bridge projects, the quality of roads and bridges is closely related to the quality of subgrade and pavement.
