The invention discloses an indoor test scheme for snow melting and deicing of an SMA asphalt mixture bridge deck pavement layer. The method comprises the following steps: (1), forming a test piece; tobe specific, forming nine test pieces respectively according to test purposes; and (2), carrying out testing by using the test pieces prepared in the (1) and carrying out snow melting and deicing tests under the conditions of three-side heat preservation and four-side heat preservation treatment of a concrete bridge deck model. According to the invention, snow melting and deicing are carried outon the test pieces under various conditions and thus the influence condition of the external environment on snow melting and deicing of concrete is obtained, thereby providing the basis for realizingrapid snow melting and deicing of roads. 本发明公开了一种SMA沥青混合料桥面铺装层融雪化冰室内试验方案，包括以下步骤，(1)、试件成型：根据试验目的分别成型9块试件，(2)利用步骤(1)制得的试件进行试验，进行在混凝土桥面板模型三面保温和四面保温处理情况下的融雪化冰试验。本发明模拟在多种条件下对试件进行融雪化冰，从而得到外界环境对混凝土融雪化冰的影响状况，为实现对道路快速融雪化冰提供了依据。
