Embodiment Construction

[0070] Drilling core samples from asphalt pavement and conducting indoor test analysis can reflect the construction uniformity of asphalt pavement, but this detection method has certain defects. At present, random methods are usually used to select points for drilling core samples on the pavement. The test results of this kind of random sampling by point instead of surface often cannot fully reflect the construction uniformity of asphalt pavement in a certain area. In the asphalt pavement construction site, the detection of the density, temperature and structural depth of the pavement can reflect the construction quality of the asphalt pavement in a certain area, but this method starts from the surface characteristics of the pavement and cannot accurately reflect the internal characteristics of the pavement in detail. Uniformity situation. It can be seen that a single detection method cannot effectively evaluate the construction uniformity of asphalt pavement.

Abstract

The invention discloses an asphalt pavement hot in-place recycling construction uniformity evaluation method, which comprises the following steps of: firstly, carrying out dense division treatment on encountered sections to obtain harmony values of the corresponding sections; then obtaining all harmony value groups Hi, and performing section marking on the sections according to the harmony value groups to obtain all stable road sections, medium road sections and inferior road sections; then uniform inspection is carried out on the stable road sections by means of related modes in sequence, and the stable road sections are correspondingly divided into corresponding first-class stable road sections and second-class accounting road sections according to inspection results; analyzing the medium road section, and marking the medium road section as a three-class accounting road section or a four-class accounting road section according to an analysis result; and finally, analyzing all obtained inferior road sections, and generating five types of accounting road sections or six types of accounting road sections according to an analysis result.

Description

technical field [0001] The invention belongs to the field of construction evaluation and relates to asphalt regeneration technology, in particular to a method for evaluating the uniformity of asphalt pavement in-situ heat regeneration construction. Background technique [0002] The patent with the publication number CN109082985A discloses a construction method for hot-in-place regeneration of asphalt pavement. The technical scheme is as follows: (1) temporary enclosure; , Adding materials; (5) secondary heating; (6) adding asphalt oil; (7) mechanical rolling; (8) open to traffic. By heating the diseased part and adding cold new asphalt and mixing on the spot, it is avoided to transport the old and new asphalt to the mixing equipment for heating and mixing, and the construction efficiency is improved. [0003] However, it lacks a corresponding method for construction uniformity detection, and the existing detection methods on the market also have corresponding defects. Based...
