As the main bearing layer of the road structure, the water stabilized base course plays an undoubted role in each structural layer. However, during the construction of Jinan water stabilized material base course, due to various reasons, there will still be some quality problems, including aggregate segregation.
Aggregate segregation is one of the quality problems that often occur in the construction of water stabilized material base course. In the construction process of water stabilized material base course of highway engineering, if each construction link cannot be well controlled, the overall strength and flatness of the base course will be seriously affected.
The segregation of aggregates will lead to the lower strength, poor flatness, poor water stability and other problems of the base course. Therefore, the highway engineering construction technicians should carry out the construction of the water stabilized material base course in accordance with the requirements of the relevant construction technical specifications and design drawings, analyze the causes of segregation, constantly summarize the experience and lessons, be more careful, less careless, more responsible, less shirking, and work together, Avoid aggregate segregation as much as possible to improve the construction quality of road works.
During the construction of the water stabilized base course, although a lot of measures have been taken to control the occurrence of segregation, it is still impossible to completely avoid the occurrence of segregation. If there is an obvious "aggregate nest" or "aggregate belt" behind the paver during the construction of the water stabilized base course, it should be handled in a timely manner. The treatment method is to arrange a 2-3 person team behind the paver to remove the mixture at the segregation position, The mixture with qualified grading shall be replaced.
During the construction of water stabilized material base course, special attention must be paid to the problem of segregation. Control must be carried out from the source, and each construction link must be strictly controlled. If segregation is found, it must be handled in a timely manner. Only the construction personnel continuously enhance their quality awareness, and carry out the construction in strict accordance with the requirements of the highway base course construction technical specifications and design documents, so as to ensure the construction quality of water stabilized material base course, Thus, the construction quality of the entire highway project can meet the requirements of relevant acceptance specifications, and its service life can be extended.
