问题 沥青贯入式面层施工步骤包括:①撒布主层集料;②压路机碾压;③浇洒沥青;④撒布嵌缝料;⑤撒布封层料。正确的施工顺序是(   )。A.①→②→③→④→②→③→④→②→③→⑤→②B.①→③→④→②→③→④→②→③→⑤→②C.①→②→④→②→③→④→②→③→⑤→②→③D.①→③→②→④→②→③→④→②→③→⑤→②→③

选项 A.①→②→③→④→②→③→④→②→③→⑤→②
B.①→③→④→②→③→④→②→③→⑤→②
C.①→②→④→②→③→④→②→③→⑤→②→③
D.①→③→②→④→②→③→④→②→③→⑤→②→③

答案 A

解析 沥青贯入式面层施工顺序:清扫基层→洒透层或粘层沥青(乳化沥青贯入式或沥青贯入式厚度小于5cm)→撒布主层矿料→碾压→洒布第一遍沥青→撒第一遍嵌缝料→碾压→洒布第二遍沥青→撒第二遍嵌缝料→碾压→洒布第三遍沥青→撒封层料→碾压→初期养护。
