Embodiment Construction

[0063] Such as figure 1A kind of asphalt pavement construction quality real-time control method shown, comprises the following steps:

[0064] Step 1. In the asphalt mixture design stage, evaluate the volume parameter characteristics of various asphalt mixtures by drawing a general map of volume parameters, and select an asphalt mixture ratio that is suitable for the local environment and is not easy to segregate. The asphalt mixture ratio The selection process is as follows:

[0065] 101. Draw the base map of the volume parameter general map: the processor uses V be is the x-axis coordinate, V a is the y-axis coordinate, according to VMA=V be +V a , VFA=V be / VMA relationship, the V a , V be , VMA and VFA four parameters are plotted on one graph; among them, V a is the porosity, V be is the volume percentage of effective bitumen, VMA is the void ratio of mineral materials, and VFA is the saturation of bitumen; figure 2 shown;

[0066] 102. Determine the volume in...

Abstract

The invention discloses a method for controlling construction quality of an asphalt pavement in real time, which comprises the following steps of: 1, drawing a universal volumetric chart to evaluate volumetric parameter characteristics of various asphalt mixtures, and selecting a proportion of an asphalt mixture, which is suitable for the local environment and is difficult to segregate; 2, checking that whether volumetric parameter information of the asphalt mixture produced in the day meets requirements of design and construction specifications so as to quickly regulate the production process; 3, evaluating the aggregation condition of the asphalt pavement by using the universal volumetric chart; and 4, analyzing and judging the compaction degree condition and temperature condition of the asphalt pavement, judging the compaction qualified rate, judging the significance of the density data difference of the asphalt pavement, checking the construction quality of the asphalt pavement and providing quantitative basis for later period payment adjustment. The method has the advantages of reasonable design, high reliability, high operability, high real-time property, high efficiency of evaluating the construction quality of the asphalt pavement, and high practicability, and contributes to improving construction quality and saving economic cost.

Description

technical field [0001] The invention belongs to the technical field of asphalt pavement construction quality control, in particular to a method for real-time control of asphalt pavement construction quality. Background technique [0002] At present, as a hot field of research, many domestic scholars have begun to study the non-uniformity of asphalt pavement construction. Since construction non-uniformity is the main cause of early disease of asphalt pavement, how to quantitatively express the non-uniformity in construction and guide the adjustment of payment after construction becomes particularly important. [0003] From the point of view of asphalt pavement construction quality control, currently available methods in China include the statistical analysis quality control method developed by Chang'an University based on the VB interface, with statistical F-test and T-test as the core. Its main feature is that it can perform F test or T test on any data, so as to judge whet...
