近几年来,公路交通建设的迅猛发展,也逐渐暴露出对自然环境的破坏问题。对此,已经引起了众多国内外专家学者的重视,坚持“宁填勿挖、减少废方,降低污染,节约造价”的原则。对于改建道路中旧路状况良好的路段按补强设计,不破坏旧路路基整体强度,根据实测弯沉值反算当量回弹模量,再计算路面厚度。
In recent years, the rapid development of road traffic construction has also gradually exposed the destruction of the natural environment. In this regard, it has attracted the attention of many domestic and foreign experts and scholars, insisting on the principle of “rather than digging, reducing waste, reducing pollution and saving costs”. For the reconstruction of roads with good roads in the old roads, the overall strength of the embankment will not be destroyed, and the equivalent elastic modulus will be calculated according to the measured deflection, and then the thickness of the road surface will be calculated.
