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
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
When use the pendulum meter determines the skid resistance value of the pavement, we must be calibrated before use.（摆式仪测定路面抗滑值，使用前必须进行标定）。
简答题
The greater the permeability coefficient of asphalt pavement indicates the better the quality of the asphalt pavement（沥青路面的渗水系数越大说明沥青路面的质量越好）。
简答题
The vehicle-mounted bump accumulator is suitable for continuous collection of roadway levelness data in the quality acceptance of new and reconstructed pavement projects(车载式颠簸累积仪适用于在新、改建路面工程质量验收中连续采集路段平整度数据)。
简答题
The rebound meter detects the strength of cement concrete pavement, and the axis of the rebound meter should always be perpendicular to the concrete pavement(回弹仪检测水泥砼路面强度，回弹仪的轴线应始终垂直于砼路面)。
简答题
Unit project refers to the construction project, according to the contract signed, with independent construction conditions(单位工程是指建设项目中，根据签订的合同，具有独立施工条件的工程)。
简答题
The use of 5.4m Beckman beam bending instrument for testing can avoid the trouble caused by the pivot point deformation.（采用5.4m贝克曼梁弯沉仪进行检测可避免支点变形带来的麻烦）。
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 strength results of cement concrete pavement slabs measured by rebound meter can be used as project acceptance（回弹仪测定的水泥混凝土路面板强度结果可以作为工程验收使用).
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
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
For highway, cement concrete surface quality assessment can be used three meters straightedge method to test pavement flatness, asphalt concrete surface is not allowed to use three meters straightedge method to test pavement flatness(对于高速公路，水泥混凝土面层质量评定可以用三米直尺法检测路面平整度，沥青混凝土面层不允许采用三米直尺法检测路面平整度)。
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 error caused by the test personnel not in accordance with the prescribed method of operation is called human error（测试人员未按规定的操作方法进行试验所引起的误差称为人为误差）。
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
Test equipment for levelness can be roughly divided into two categories: section type and reaction type(平整度的测试设备大致可分为断面类和反应类两大类)。
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
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
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）。
