沥青道路的施工工艺是怎样的？其中喷洒沥青的作用是什么？可以以动画的形式直观展示沥青道路施工工艺，重点突出喷洒沥青的工艺。---**Textual Information:** * **Main Title:** 乡村道路施工工艺 (Rural Road Construction Process) * **Road Layer Labels (from top to bottom on the diagram):** * 改性沥青混凝土 (Modified Asphalt Concrete) * 上封层 (Upper Seal Coat Layer) * 粘 层 (Tack Coat Layer) * 下封层或透层 (Lower Seal Coat Layer or Prime Coat Layer) * 水稳碎石 (Cement-stabilized Crushed Stone) * 基层 (Base Layer) * 素填土 (Plain Fill Earth) * 路基 (Subgrade) * **Layer Functions/Descriptions (from top to bottom on the right side of the diagram):** * **上封层:** 防水抗滑、延缓老化 (Waterproof and anti-skid, delay aging) * **粘 层:** 新、旧路面的粘结 (Bonding of new and old pavements) * **下封层或透层:** 加强粘结、防水护基 (Strengthen bonding, waterproof and protect base) * **Research Statement:** * **研究表明:** (Research shows:) * 封层、粘层、透层对道路质量的影响比例占据53% (The influence proportion of seal coat layers, tack coat layer, and prime coat layer on road quality accounts for 53%) **Chart/Diagram Description:** * **Type:** An illustrative cross-section diagram showing the layered structure of a rural road, accompanied by textual explanations of each layer's function and a research finding. * **Main Elements:** * **Title Area:** Located at the top, featuring a green circular icon with a white road symbol (two parallel dashed lines) and the main title "乡村道路施工工艺" (Rural Road Construction Process) in green text. * **Road Structure (Left Side):** A 3D perspective representation of a road cross-section, showing distinct layers stacked vertically. * The topmost thick layer is labeled "改性沥青混凝土" (Modified Asphalt Concrete). * Immediately below it are three thinner layers, from top to bottom, which are pointed to by green lines: * The first thin layer (directly under Modified Asphalt Concrete) is for "上封层" (Upper Seal Coat Layer). * The second thin layer is for "粘 层" (Tack Coat Layer). * The third thin layer is for "下封层或透层" (Lower Seal Coat Layer or Prime Coat Layer). * Below these thin layers is a thick grey block labeled "水稳碎石" (Cement-stabilized Crushed Stone) on its left and "基层" (Base Layer) on its right. * The bottommost layer is a white/light grey block labeled "素填土" (Plain Fill Earth) on its left and "路基" (Subgrade) on its right. * **Explanatory Text Boxes (Right Side):** * Three green text boxes on the right describe the functions of the "上封层," "粘层," and "下封层或透层." Green lines with circular markers connect these text boxes to their corresponding thin layers in the road structure. * Below these, a larger green text box contains the heading "研究表明:" (Research shows:) and a concluding statement about the impact of the seal coat, tack coat, and prime coat layers on road quality. * **Background:** The entire diagram is set against a light green and grey textured background with a faint grid of white dots, suggesting a technical or schematic drawing style.
