Check that the surface is smooth, firmly compacted and atcorrect cross section, grade, and alignment. Existingbituminous and concrete bases are to be clean and free ofloose material, and tacked. Excessive joint and cracksealing material should be removed. Pre-level all Ensure that truck boxes are clean to prevent build-up (donot use kerosene, diesel fuel or fuel oil).

Review grading and erosion and control Inspect clearing and grubbing limits, and measurequantities. Check contract for disposal of firewoodand Monitor salvaging of topsoil to ensure properdrainage and erosion Insure unstable material below subgrade is undercutand measured for final pay.
