简答题The three-meter straightedge method can be used for highway surface leveling inspection(三米直尺法可用于高速公路面层平整度验收)。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Roadbed compaction index shall be tested in each layer, but score only according to the test data of the upper section(路基压实度指标须分层检测，但只按上路段的检测数据计分)。简答题The rebound method of testing the strength of concrete method does not reflect the internal quality of concrete, is an easy and fast method suitable for census concrete strength(回弹法检测混凝土的强度法不能反映混凝土内部质量，是一种适用于普查混凝土强度的简便、快速的方法)。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)。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Pendulum meter to determine the pavement skid resistance value, when the pavement test temperature of 20 ℃, no temperature correction（摆式仪测定路面抗滑值，当路面试验温度20℃时，不进行温度修正）。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）。
