摘要
中原油田原来修建的沥青道路，经过一个冻融期，路面便出现横向裂缝。这对工程竣工验收质量评定影响甚大。经多次攻关试验，在东明黄河大桥北岸边路工程中，采用了石灰、土、碎石什匕例为人2：52：8：40）作为道路的基层，路面层采用了下部为4m厚的乳化沥青贯入式，上部为3cm厚的细粒式沥青硅。经过一个冻融期的通车考验，路面未出现任何裂缝。文中介绍了采取此方法以防止沥青路面裂缝的措施。
The asphalt road former constracted in Zhongyuanoilfield through a freezing-melting perind, thetransversal rifts on road surface appear. In accordance with the problem, throngh many times oftackling key problem tests and on the high wgy engineering of north bank of YellowRiver, bridge,thehighway's base tier adopts lime, earth, cruChedstones (7. 2: 52. 8: 4o), pavement's under pmadopts 4 cm emulsified asphalt penetration and up-per tier adopts 3 cm tiny grain bituminous 'con-cretes. Through the test of a freezing-melting peri-od there has no any rift on the pavement.
