From Engineering_Policy_Guide
Jump to navigation Jump to search

The roadway inspector’s primary responsibility is to assure the placement of mixes to produce a smooth surface meeting the requirements of thickness, density, and cross section established by the contract. To do so, the inspector should understand and be familiar with all paving operations and equipment. Inspectors assigned to the roadway receive material tickets, check for correct truck tarping procedures, check temperatures, observe the placement and compaction of mix, check yield, straightedge and profilograph the surface, and procure density samples.

It is important for the inspector to respond to inspection requests promptly and to be consistent in those inspection procedures. The contractor should be notified immediately of any problems that are observed by the inspector. Also, the inspector must maintain open lines of communication with all of the parties involved in the paving operation. Finally, the inspector will maintain complete and accurate records.

Inspection personnel will have a copy of the plans, the contract and applicable special provisions, Standard Specifications, the approved job mix formula, and enough forms and field books to document all pertinent information and all work and materials to be paid for. Upon completion of a project, all records are maintained by the District Office.
