Expressway maintenance method
The invention belongs to the technical field of expressway maintenance methods, and particularly relates to an expressway maintenance method. The expressway maintenance method comprises the followingsteps of S1, firstly, laying cotton felt on a road section with serious oil flooding, uniformly spraying water to the surface of the cotton felt for cooling, and waiting for saturation of water absorption of the cotton felt; and S2, after an asphalt pavement is dried, fixedly mounting a spreading device at the front end of a heavy road roller, and then filling gravels with different grain size gradations into a storage box positioned at a top layer in the spreading device. According to the expressway maintenance method, the gravels can be evenly spread on the road surface while being screened,so that the step of screening the gravels can be omitted, time and labor are saved, and the working efficiency can be greatly improved; and compared with manual spreading, the spreading device is more uniform and more labor-saving, the gravels in certain gradation are classified according to large, medium and small particle sizes, the gravels with large particle sizes are firstly paved and pressed into the asphalt pavement, and then the gravels with small particle sizes are paved and pressed into the asphalt pavement, so that the roadbed stability is improved.
本发明属于高速公路养护方法技术领域，具体的说是一种高速公路养护方法,包括S1:首先先在泛油严重路段铺设棉毡，向棉毡的表面均匀的喷洒水进行降温，待棉毡吸水饱和后；S2:待沥青路面干燥后，再将撒料装置固定安装在重型压路机的前端，然后向撒料装置中位于顶层的储料箱内装入粒度级配不等的碎石；本发明可边将碎石均匀的洒在路面上，边对碎石进行筛分，从而可以省略对碎石的筛分步骤，不仅省时省力，且可大大提高工作效率，且本发明的撒料装置跟人工撒料相比更加的均匀且省力，且通过将一定级配中的碎石按照大、中、小粒径进行分类，先将大粒径碎石进行摊铺，压入沥青路面，然后再将较小粒径的碎石进行摊铺，压入沥青路面，提高路基稳定性。
