About this deal
ReferencesT.S.O. - Highways Agency - Specification for Highway Works. This document details requirement in term of the maximum permissible number of irregularities beneath a Rolling Straight edge. This method of testing is described in both BS8204-Part 1:2003 and BS8204-Part 2:2003. A 2m straight edge is used in both specifications. Optional 2.5 mm incremented wedges are available, which offer a range of 12.5 mm low to 12.5 mm high. Specifications SpecificationThe rolling straight edge is shipped in 3 wooden cases with a total gross weight of 112kg. The Rolling Straight edge was developed in conjunction with TRL.

These straight edges are designed for levelling and finishing wall and floor surfaces. The section is 76mm x 38mm. TRL - Supplementary Report 290 - details the calibration, maintenance and use of the Rolling Straight edge. The Rolling Straight edge measures depressions on the pavement surface on analogue scale 0-12mm + 0.25mm. The straight edge also has an odometer for accurate determination of distance travelled in units of 1 metre. For a proposed revision of BS 8204 in 2003, a straight edge with feet was again suggested, which was intended to be more portable than the 3m straight edge. This consistedof a collapsible 3m long frame with a wire stretched to standard tension from which to measure the deviation was proposed. This method was rejected in favour of a 2m straight edge set on the slab and is the methodis adoptedin the currentBS 8204,BS EN 13670 Execution of concrete structures, the National Structural Concrete Specification and National Building Specification.
