Method for detecting the texture of asphalt road face through simulated human eye identification technology

Abstract

The invention discloses a method for detecting the texture of an asphalt road face through simulated human eye identification technology. The method is performed through the following steps: calculating the texture depths of a asphalt road face at test spots through the analysis and processing of the asphalt road face's digital image simulation and identification; and calculating the relationship between the texture depths of the asphalt road face on one hand and the composition of mixed materials and the use amount of asphalt on the other so as to further evaluate the composition of the mixed materials on the asphalt road face and the use amount of asphalt. Compared to the prior art, the method provided in the invention uses a simulated digital image technology to measure the texture depths of an asphalt road face, the composition of mixed materials and the use amount of asphalt. Further, the method is high efficient, cost-effective, and simple to operate. In addition to that, since the method is performed without chemical agents, the safety of workmen is guaranteed. As a damage-free detection process, it does not require any alteration of the road, thus helping keep the road intact.

Description

technical field [0001] The invention relates to a method for detecting the composition of asphalt pavement materials and the amount of asphalt. Background technique [0002] At present, the commonly used methods for determining the amount of asphalt and grading inspection include centrifugal separation method, ray method, and combustion furnace method. [0003] Centrifugal separation is a standard method for determining asphalt content. The principle of determining asphalt content is to use trichlorethylene liquid to soak the sample, so that the asphalt and aggregates are discharged from the asphalt solution in the high-speed rotation of the centrifuge, and repeatedly added to the sample. Extract with new trichlorethylene until the outflowing extract is clear. The disadvantages of centrifugation are: 1. Trichlorethylene, the main chemical reagent used in the determination, is harmful to human health. Trichlorethylene mainly has an anesthetic effect on the central nervous sy...

Problems solved by technology

The disadvantages of centrifugation are: 1. Trichlorethylene, the main chemical reagent used in the determination, is harmful to human health. Trichlorethylene mainly has an anesthetic effect on the central nervous system, and can also cause liver, kidney, heart, and trigeminal nerve damage. , short-term contact or inhalation of a large amount of this product can cause acute poisoning

2. The measurement time is long, the accuracy of the test results is low, and it is very important to calibrate the amount of ore powder leaked into the extract during the operation, otherwise the measured oil-stone ratio may be too large every time

[0004] The disadvantages of the ray method are: 1. There are restrictions on the type of mixture. It is suitable for hot mix mixture of viscous petroleum asphalt, but not suitable for the determination of asphalt content in other asphalt mixtures.

[0005] The disadvantages of the combustion furnace method are: 1. When fiber or combustible materials are added to the mixture, it is not suitable for the determination of the combustion furnace method. Due to the combustion characteristics of the admixture itself, part of the mass will be lost during the combustion process, which will eventually affect the asphalt. Content test results
