Embodiment 1

[0043] In this embodiment, pavement and quality inspection are carried out on the pavement of Chizhou City, a pilot city for sponge city construction. The length of the test section of drainage asphalt concrete in Chizhou sponge city is 170m, and the double-layer drainage asphalt pavement is carried out on the basis of the original 8cm AC25 densely graded asphalt concrete. For construction, 5cm PAC20 or PAC16 drainage asphalt concrete is used as the middle surface layer, and the corresponding upper layer is 4cm PAC13 or PAC10 drainage asphalt concrete. Set a slurry seal layer between the lower layer and the middle surface layer to achieve the effect of water tightness.

[0044] The test section is paved in the west right lane of Xiangyun Avenue. The estimated paving length is 200 meters, the actual paving length is 170 meters, the starting pile number is K0+180, and the ending pile number is K0+340. Since the central motor vehicle separation strip 3 is reserved in the center o...

Abstract

The invention provides a double-layer drainage asphalt pavement quality detection method which comprises the following steps: step 1, sampling and incinerating an asphalt mixture before pavement laying to determine the asphalt consumption; the remaining mineral aggregate after incineration is screened, and the grading composition of the mixture is detected; 2, taking the asphalt mixture on site, forming a Marshall test piece, and testing performance indexes of the Marshall test piece; 3, the bituminous mixture is subjected to actual pavement laying, and after laying is completed, sampling is conducted to detect the pavement performance; and 4, carrying out pavement core drilling sampling on the detection road section, and carrying out industrial CT scanning on the core sample to obtain theinternal pore characteristics and spatial distribution of the core sample. The detection method disclosed by the invention can be used for timely and effectively monitoring the material consumption deviation in construction and providing timely feedback for mixture mixing; meanwhile, on-site construction links are managed and controlled, and the construction quality is guaranteed; the test resultis accurate and reliable, and practical guidance is provided for further optimization of the grading design of the permeable asphalt concrete.

Description

technical field [0001] The invention belongs to the technical field of asphalt pavement quality detection, and in particular relates to a double-layer drainage asphalt pavement quality detection method. Background technique [0002] The construction quality of asphalt mixture significantly affects the service life and service level of asphalt pavement. For double-layer drainage asphalt pavement, drainage performance is the key factor affecting the service life of the pavement. Therefore, it is necessary to strictly control the quality of the construction pavement and reasonably detect the construction of asphalt pavement The final condition, water seepage, friction coefficient and smoothness of the construction road surface, and the performance of asphalt concrete are all very important testing items in order to accurately understand the gradation control and asphalt ratio in the production process of the mixture. The performance detection data timely corrects and guides the...
