级配碎石柔性加铺层铺筑技术研究

Study of laying technology of flexible intensified layer with graded macadam

根据唐山市205国道旧水泥混凝土路面加铺改造的实践,对级配碎石柔性加铺层的工艺进行了深入研究,并对其经济性进行了对比分析,认为在旧水泥混凝土路面与沥青加铺层之间铺筑优质级配碎石的方法,是一种技术上可行、经济上合理的施工新技术。

Based on the practice of flexible intensified layer on the existing cement concrete pavement of the National High- way No. 110 within Tangshan City, this article makes a deep study of construction technology for the layer of graded macadam, with compared to economy analysis. It is considered that paving method of graded macadam between cement concrete pavement and extra - paving layer is a new technology which is feasible in technique and reasonable in economy.
