Embodiment Construction

[0039] In order to describe the technical solution disclosed in the present invention in detail, further elaboration will be made below in conjunction with the accompanying drawings and specific embodiments.

[0040] In the process of grouting pavement construction, the grouting fullness is an important index to evaluate its quality, which directly affects the anti-rutting ability, water damage resistance and durability of the pavement. However, in the current testing, there is no method to detect the fullness of the pavement after grouting. Therefore, accurate detection of the saturation after grouting can effectively evaluate the construction quality and play an important role in reducing road surface diseases. Aiming at this technical problem, the present embodiment firstly prepares the grouting test piece. For this, the prior art shows that the grouting mixture (GAC) is composed of porous asphalt mixture skeleton (PAC) and cement-based grouting material (GM). In this examp...

Abstract

The invention discloses a method for detecting grouting fullness of a cement-based grouting material, which comprises the following steps of: effectively distinguishing a grouting material, an asphalt mixture and a gap by adopting modes of two-dimensional slicing, image segmentation and the like according to color differences of the grouting material, the asphalt mixture and the gap, and automatically calculating the areas of the grouting material and the gap by adopting matlab; and respectively accumulating the areas of all the grouting materials and gaps on each slice, and then calculating the grouting fullness of the grouting test piece. The method provided by the invention solves the problem that the actual grouting fullness measured by a conventional test method is too high due to the fact that the conventional test method only considers the holes of which the communicated holes are not filled with the grouting material.

Description

technical field [0001] The invention belongs to road asphalt detection technology, and in particular relates to a detection method for filling fullness of cement-based grouting materials. Background technique [0002] With the rapid increase of traffic load and traffic volume, rutting has become one of the main diseases of asphalt pavement, seriously affecting the durability and comfort of the pavement. Studies have shown that the composite pavement paved with perfusion mixture has excellent anti-rutting performance. Perfused asphalt mixture (GAC) consists of two parts: porous asphalt mixture skeleton (PAC) and cement-based grouting material (GM). Among them, the perfusion saturation of GM has a significant impact on the performance of GAC. The high porosity of PAC and the sufficient fluidity of GM are the key factors to ensure full perfusion of GAC. Therefore, in the process of grouting pavement construction, the grouting saturation is an important index to evaluate its ...
