Example Embodiment

[0088] The construction process of the large-area lime soil road mixing method of the present invention includes a "three-stage, five-section, and ten-process" construction process, in which the three stages include the preparation stage, the construction stage, and the renovation and acceptance stage; the preparation stage includes construction preparation and There are two processes for substrate treatment; the construction phase includes five sections, the five sections are: filling section, mixing section, leveling section, rolling section, and testing section. Among them: filling section includes Layered filling process; the mixing section includes two processes of initial pressing and leveling and ash distributing and mixing; the leveling section includes two processes of filling fine leveling and sprinkling and drying; the rolling section includes the rolling compaction process; the inspection section includes the inspection and visa process ; Refurbishment acceptance stage...

Abstract

The present invention discloses a large-area double-ash lime soil pavement mixing construction process and its quality control detection method. Said construction process includes preparation stage, construction stage and finishing acceptance stage. In the lime-spreading and mixing process of construction stage the lime-spreading quantity can be defined by utilizing vehicle automatic computing system to regulate vehicle speed and belt roller rotating speed. Besides, it adopts road-mixing machine and road roller to make road-mixing operation and pavement-ramming operation. Its detection method is characterized by adopting cutting ring method to detect degree of compaction and adopting small-plate loading instrument to detect strength and deformation.

Description

technical field [0001] The invention relates to road construction technology, in particular to a large-area fly ash and lime soil road mixing construction technology for building high-quality racing track roads. Background technique [0002] For the construction of roads of high-quality racing circuits, such as F1 racing circuits, the construction period is very tight, the project volume is huge, and the quality requirements are high. Among them, fly ash and lime soil are used in a very large amount, and the existing lime soil and lime soil construction technology cannot meet the site's requirements for output and quality at the same time. [0003] There are three existing construction techniques for lime or fly ash, which are: road-mixing construction technology, centralized site road-mixing construction technology and field-mixing construction technology. in: [0004] The road mixing method refers to directly transporting the filler to the place where it needs to be fill...
