Do you know what information is included in the inspection items of asphalt concrete pavement engineering quality? In fact, most people have never known about this. Now, Jinan asphalt concrete manufacturer will give you some answers.
1、路基:压实度(检查方法:灌水法、灌砂法或环刀法；检查频率:每1000平方取每压实层抽查3点);道路弯沉(检查方法:弯沉仪检测;检查频率:每车道、每20m测1点);
1. Subgrade: compactness (inspection method: water filling method, sand filling method or circular knife method; inspection frequency: 3 points per 1000 square meters for each compacted layer); Road deflection (inspection method: deflectometer detection; inspection frequency: 1 point per 20 m per lane);
2、基层:原材料质量检测(检查方法:查检验报告、复验;检查频率:按不同材料进场批次，每批检查一次);压实度(检查方法:灌水法、灌砂法;检查频率:每1000平方取每压实层抽查3点);基层、底基层试件作7d无侧限抗压强度，(检查方法:现场取样试验;检查频率:每2000平方抽检1组(6块));道路弯沉(检查方法:弯沉仪检测;检查频率:每车道、每20m测1点);
2. Base course: quality inspection of raw materials (inspection method: check the inspection report and re inspection; inspection frequency: check each batch according to different materials' arrival batches); Compactness (inspection method: water filling method, sand filling method; inspection frequency: 3 points per 1000 square meters for each compacted layer); 7d unconfined compressive strength of base and subbase test pieces (inspection method: on-site sampling test; inspection frequency: 1 group (6 pieces) per 2000 square meters); Road deflection (inspection method: deflectometer detection; inspection frequency: 1 point per 20 m per lane);
3、沥青面层:
3. Asphalt surface course:
原材料质量检测(沥青:检查方法:查出厂“合格证、检验报告并进场复验;检查频率:按同一厂家、同一品种、同一标号、同一批号进场的沥青(石油沥青每100t为一批，改性沥青每50t为一批)每批次抽检一次;
Quality inspection of raw materials (asphalt: inspection method: check the factory's "certificate of conformity" and "inspection report" and conduct re inspection on the site; inspection frequency: spot check each batch of asphalt (petroleum asphalt every 100t is a batch, modified asphalt every 50t is a batch) delivered by the same manufacturer, the same variety, the same grade and the same batch number;
沥青混合料所用的粗集料、细集料、矿粉、纤维稳定剂等:检查方法:观察、检查进场检验报告;检查频率:按不同品种产品进场批次和产品抽样检验确定);
Coarse aggregate, fine aggregate, mineral powder, fiber stabilizer, etc. used for asphalt mixture: inspection method: observe and check the mobilization inspection report; Inspection frequency: determined according to the incoming batches of different varieties of products and product sampling inspection);
沥青混合料:检查方法:测温;检查频率:全数检查);沥青混合料马歇尔试验:(检查方法:现场取样试验;检查频率:每日、每品种取样一次);
Asphalt mixture: inspection method: temperature measurement; Inspection frequency: full inspection); Marshall test of asphalt mixture: (inspection method: on-site sampling test; inspection frequency: once a day for each type);
压实度(检查方法:马歇尔试验;检查频率:每1000平方取抽查1点);
Compactness (inspection method: Marshall test; inspection frequency: 1 point per 1000 square meters);
面层厚度:(检查方法:钻孔或刨挖;检查频率:每1000平方取抽查1点);道路弯沉(检查方法:弯沉仪检测;检查频率:每车道、每20m测1点)。
Thickness of surface course: (inspection method: drilling or digging; inspection frequency: 1 spot for every 1000 square meters); Road deflection (inspection method: deflectometer detection; inspection frequency: 1 point per 20 m per lane).
