Rolling Straightedge

Rolling Straightedge Apparatus Geotechnical Testing Equipment The rolling straight edge (also rolling straightedge or planograph) is an instrument used to measure the surface regularity of roads and similar structures such as airport runways. What is a rolling straight edge? a rolling straight edge is a measuring tool used in construction to check the smoothness and evenness of paved surfaces such as concrete slabs, highways, and runways.

Pavements Fhwa Infotechnology High low detector (rolling straight edge) used to measure planeness of pavement surfaces, such as highways, airport runways, bridge decks, etc. requires only one operator to detect, register, and dye mark high and low areas that need to be ground down or filled. It is produced as an instrument to assist engineers with construction, quality control and with compliance assessment, of newly laid pavement regularity. the rolling straight edge measures depressions on the pavement surface on analogue scale 0 12mm 0.25mm. This document describes a method for determining the longitudinal regularity of a road surface using a rolling straight edge. the rolling straight edge apparatus consists of a 3.05m frame carried on 40 fixed wheels used to measure deviations in the road surface. To overcome this difficulty, a 3 m electronic rolling straight edge (erse) is fabricated. the erse is a portable apparatus which is used for quickly assessing the surface condition of a road,.

The rolling straightedge measures depressions on the pavement surface on analogue scale 0 12mm 0.25mm. the straightedge also has an odometer for accurate determination of distance travelled in units of 1 meter. A rolling straight edge is a precision engineering tool designed to measure the surface regularity and planeness of pavements, including highways, airport runways, and bridge decks, by detecting and quantifying high and low deviations through a rigid wheeled frame and integrated gauge. 2.1 rolling straightedge – the rolling straightedge should be 15 feet ± 2 inches in length measured from center to center of the wheel axles and in good working order. the rolling straightedge should have a read out gauge with low and high reading marks to the nearest 1 16 inch. It is produced as an instrument to assist engineers with construction, quality control and with compliance assessment, of newly laid pavement regularity. the rolling straight edge measures depressions on the pavement surface on analogue scale 0 12mm.
