⒈施工準備
⑴ 施工測量
在開工前先進行施工測量，包括導線、中線及高程的復測，水準點的復查與增設，測量與繪制橫斷面。施工測量的精度符合《公路勘測規程》（JTJ061-99）的要求。并將測量方法及成果資料簽字后交送監理工程師。經監理工程師批準后方可施工。
在開工之前在現場放出路基坡腳、路塹塹頂、截水溝、邊溝、護坡道、取土坑、棄土場等的具體位置，標明其輪廓，提請監理工程師檢查批準。
⑵ 調查與試驗
路基施工前對施工范圍內的地質、水文、障礙物、及各種管線等情況進行詳細調查。
對圖紙所示的利用挖方、借土場的路堤填料取有代表性的土樣進行試驗，試驗方法按《公路土工試驗規程》（JTJ051-93）執行，試驗項目按 “技術規范”要求進行。
⑶ 防水、排水
施工前做好路基的各種防、排水設施，挖設排水溝，并保持其處于良好的排水狀態。
⑷ 清理場地
⒈ construction preparation
⑴ construction survey
To start construction before the measurement, including wire, middle and elevation of the retest, and the additional level of review points, measuring and drawing of cross section. Construction of measuring the accuracy of line "Highway Survey and order" (JTJ061-99) requirements. And measurement methods and results of data delivery after the signing of supervision engineer. By the supervising engineer for approval before construction.
Released at the scene before the start embankment slope, the top cutting cutting, drainage ditches, ditches, slope protection Road, take the pit, the specific location of dump yards, marking the outline, draw the supervision engineer inspection approval.
⑵ investigation and trial
Before the construction of roadbed construction within the scope of geology, hydrology, obstacles, and various pipelines for detailed investigation.
Shown on the drawings using excavation, embankment by earth field to take a representative soil samples to test, test methods according to "road soil test procedures" (JTJ051-93) implementation of pilot projects in accordance with "Technical Standards" requirements.
⑶ water, drainage
Well before construction of various anti-roadbed, drainage facilities, located dug drainage ditches, and to maintain its good drainage in the state.
⑷ cleaning up the site
