| Abstract: | Coal gangue as waste to the characteristics of its low cost, high benefit, environmentally friendly, more and more applied in highway roadbed. In cold regions, how to join the new and old road of coal gangue together is a hot problem which many project will focus on it. In this paper, the causing the old and new embankment settlement mechanism were analyzed. According to reasons which cause the differential settlement of the joint part of subgrade of coal gangue, proposed common approach to prevent the junction of gangue differential settlement of subgrade. Provide a reference for highway subgrade of coal gangue widening in cold regions. |
