Embodiment Construction

[0034] Such as figure 1 and figure 2 Shown, the asphalt pavement compactness real-time monitoring method of the present invention comprises the following steps:

[0035] Step 1. Establish a linear relationship between the degree of compaction and the detection density of the non-nuclear density meter. The specific process is:

[0036] Step 101. First, prepare a plurality of rutting slabs with different compaction degrees in the laboratory using the pavement material of asphalt pavement, and then detect the density of each rutting slab with a non-nuclear density meter;

[0037] In this embodiment, the number of rutting plates in step 101 is 3-5.

[0038] Step 102, take the density detected by the non-nuclear density meter as the abscissa, and the degree of compaction of the rutting plate as the ordinate, draw a relationship curve between the density detected by the non-nuclear density meter and the degree of compaction, and perform a calculation on the drawn relationship cur...

Abstract

The invention discloses a real-time asphalt road compactness monitoring method which comprises the steps of (1) establishing a linear relation between compactness and detection density of a non-nuclear density gauge; (2) establishing a linear relation between a compaction value and the compactness; (3) according to the lower compactness limit requirement of a construction site and according to the linear relation between the compaction value and the compactness, established in the step (2), determining the lower limit of the compaction value; (4) monitoring the compactness in construction in real time, enabling an vibratory roller operator to control a vibratory roller through observing the compacted or uncompacted information displayed on an industrial control computer, continuously rolling when in uncompaction, and stopping rolling when in compaction. The real-time asphalt road compactness monitoring method is novel and reasonable in design, convenient to realize, capable of improving the compaction quality and efficiency of an asphalt road and avoiding damage to the road, relatively high in compactness detection accuracy, low in realization cost, strong in practicability, and high in popularization and application values.

Description

technical field [0001] The invention belongs to the technical field of asphalt pavement compaction quality control, in particular to a method for real-time monitoring of asphalt pavement compaction. Background technique [0002] Compaction is a very important link in the construction of asphalt pavement. The purpose of compaction is to make the pavement material reach the specified density, so as to resist the driving load and the environment. Effective compaction of asphalt pavement can significantly improve the bearing capacity, smoothness, stability, durability, etc. of the pavement, and the compaction quality directly determines the safety and service life of the road. The degree of compaction is an important index to evaluate the quality of compaction, and its detection accuracy and real-time control are hot issues in the field of compaction. [0003] With the significant improvement of the mechanization level of pavement construction in my country and the use of advan...
