This article establishes procedures for inspecting, sampling and reporting polyethylene sheeting. Refer to [ Sec 1058] for MoDOT’s specifications.
The Resident Engineer may accept polyethylene sheeting, for use in curing Portland cement concrete or use as a bond breaker between a bridge approach slab and a granular base. However, if Construction and Materials is requested to perform inspection, the material may be accepted on the basis of manufacturer's certification or sampling and testing, if deemed necessary. When a shipment is sampled, the number of rolls to be sampled is one half the square root of the number of rolls, rounded to the nearest whole number, in the shipment. A sample is to consist of a strip 18 in. (450 mm) long by the width of the roll and is to be cut at least 5 ft. (1500 mm) from the end of the roll. The samples are to be submitted to the Laboratory for testing through SiteManager.
A list of those manufacturers who have submitted for New Product Evaluation and provided certification that their product meets the requirements of Sec 1058 is below.
