Double-layer drainage asphalt pavement quality detection method
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.
本发明提供一种双层排水沥青路面质量检测方法，包括如下步骤：步骤一，对路面铺设之前的沥青混合料进行取样，焚烧测定沥青用量；对焚烧剩余的矿料筛分，检测混合料的级配组成；步骤二，对所述沥青混合料现场取料，成型马歇尔试件，测试其性能指标；步骤三，将所述沥青混合料进行实际路面铺设，铺设完成后抽样检测所述路面性能；步骤四，在检测路段进行路面钻芯取样，对芯样进行工业CT扫描，获得所述芯样内部孔隙特征和空间分布。本发明的检测方法，能够针对施工中材料用量偏差进行及时有效监测，为混合料拌制提供及时反馈；同时对现场施工环节进行管控，保障施工质量；测试结果准确、可靠，为透水沥青混凝土级配设计的进一步优化提供实践指导。
