(1) Existing asphalt surface:
(a) Excavation shall be filled with thoroughly compacted sand to a depth not less than ten inches below finished grade;
(b) Portland cement concrete with a 3,000 psi minimum shall be deposited on top of the sand fill to within one inch below finished grade;
(c) After portland cement concrete has cured for a minimum period of four days, asphaltic primer RC-3 shall be applied at a rate of 0.5 gallons per square yard;
(d) A one-inch course of hot asphaltic concrete, Indiana State Highway Department, Type B shall be applied, thoroughly compacted and rolled. If the weather is unsuitable for properly applying hot asphaltic concrete for repairing the surface, a temporary patch may be applied consisting of asphalt coated aggregate (cold patch), provided that when suitable paving weather occurs, the temporary patching materials shall be removed and replaced with hot asphaltic concrete as specified above.

(b) The remaining depth shall be filled with crushed stone of the size required by the Street Commissioner.
(4) Existing earth surface: Excavation shall be filled with earth, and earth mounded above the excavation to a height above finished grade amounting to 10% of the depth of the excavation. After settling has occurred, earth shall be added or removed to level the fill with finished grade, and the surface restored to the same condition as existed before excavation was made.
(B) Exploratory drill holes shall be filled in the same manner as trench or pit excavations, except that when the holes are made in an existing earth surface, it shall be refilled with sand except the upper six inches of fill material, which shall be earth.
