简答题
Highway testing and inspection personnel should be realistic, loyal and decent (公路试验检测人员要实事求是、忠于职守，作风正派)。
简答题
For sampling the borehole or cut pavement potholes, the same type of material should be used to fill the compaction, sampling the moisture left behind should be absorbed by cotton yarn, etc. to be dried and then replenished（对取样的钻孔或被切割的路面坑洞，应采用同类型材料填补压实，取样时留下的水分应用棉纱等吸走待干燥后再补充）。
简答题
For the evaluation of the compaction of earth roadbed, the standard density determination method is the heavy compaction test method(对于土方路基压实度评定，标准密度的测定方法是重型击实试验法)。
简答题
The quality of field compaction is expressed by compaction degree(现场压实质量用压实度来表示)。
简答题

简答题
The quality of field compaction is expressed by compaction degree(现场压实质量用压实度来表示)。
简答题
In filling sand test, the loose square density must be measured for each change in the amount of sand(灌砂试验时，每换用一次量砂，都必须测定松方密度)。
简答题
The falling hammer bending instrument belongs to the dynamic test method, and its determination of the bending is dynamic rebound bending（落锤式弯沉仪属于动态测试方法，其测定的弯沉为动态回弹弯沉）。
简答题

简答题
Drilling method to determine the thickness of the pavement drilling core samples are available to clean and spare with water(钻孔法测定路面厚度钻取芯样都可用清水清洗干净备用)。
简答题
The quality assessment of highway engineering major and medium repairing project is based on "Highway Engineering Quality Inspection and Assessment Standard" JTGF80/1-2017(公路工程大、中修工程质量评定依据《公路工程质量检验评定标准》JTGF80/1-2017)。
简答题
When the thickness of the layer is measured by drilling core sampling method, and the average value is taken as the thickness of the layer from two symmetrical points in the core sample（ 钻芯取样法测定厚度时,从芯样中取对称的两点测定，取其平均值作为该层的厚度）。
简答题
Friction coefficient determination vehicle to determine the pavement transverse force coefficient test when the bilateral determination, the test results should take the average of the two sides（ 摩擦系数测定车测定路面横向力系数试验当双侧测定，其各侧测点结果互不相关，各自取值）。
简答题
When the representative value of pavement inspection thickness is less than the design thickness minus the allowable deviation of the representative value, the thickness index is rated as zero（当路面检测厚度代表值小于设计厚度减去代表值允许偏差时，则厚度指标评为零分）。
简答题
The error caused by the minimum physiological resolution and inherent habits of the testers is called human error（测试人员生理上的最小分辨率和固有习惯引起的误差称为人为误差）.
简答题
In filling sand test, the loose square density must be measured for each change in the amount of sand(灌砂试验时，每换用一次量砂，都必须测定松方密度)。
简答题
The fine structure of the road surface usually plays a decisive role in the skid resistance performance of the road surface at low speed（路表面细构造通常在低速时对路表抗滑性能起决定作用）。
简答题
Rebound method to test the strength of concrete a total of 16 points per measurement area, 16 rebound values of the three maximum and minimum values were excluded(回弹法检测混凝土的强度每测区共弹击16点，16个回弹值中分别剔除三个最大值和最小值)。
简答题
The percolation coefficient refers to the volume of water percolating into the specified pavement per unit of time at a specified initial head pressure（渗水系数指在规定的初始水头压力下，单位时间内渗入规定路面的水的体积）。
简答题
When the compaction test is carried out by the sand filling method, the thickness of the structural layer can be obtained by measuring the depth of the test pit(当用灌砂法进行压实度检测时，可通过量取试坑的深度，从而得到结构层的厚度)。
