沥青混凝土摊铺层质量的重要指标是平整度和密实度,而摊铺机则对最终形成的摊铺层起重要作用。然而,施工中的许多因素又直接对摊铺机的工作产生影响,例如:混合料的级配及温度、钢丝基准线的架设与测量、摊铺起步与暂停、摊铺速度、振动频率、摊铺层纵向搭接、混合料离析以及碾压方法等。因此,施工中应做好与上述因素有关的工作,以保证摊铺层的质量。 An important indicator of the quality of asphalt concrete paving is the flatness and density, while the paver plays an important role in the final form of the paving layer. However, many factors in construction affect the work of the paver directly. For example, grading and temperature of the mixture, erection and measurement of the wire baseline, start and stop of paving, paving speed, vibration frequency, booth Laying vertical lap, mixture segregation and rolling methods. Therefore, the construction should be done with the above factors related to the work in order to ensure the quality of the paving layer.
