DEFLECTION IN M1 MOTORWAY CARRIAGEWAY DUE TO SETTLEMENT OF BACKFILLED OPENCAST COAL SITE, STRELLEY, NOTTINGHAMSHIRE, ENGLAND
The maximum of the observed and measured deflections were of the order of 250mm, sufficiently significant to present an element of danger to fast moving traffic, especially in wet conditions. This article describes a comprehensive site investigation aimed at arriving at a viable solution to the problem. Two practicable solutions were retained: 1) the construction of vertical drains in pre-bored holes in a triangular pattern over the width of the existing carriageways; 2) continued maintenance and resurfacing of the section. The latter was considered the best option for the following reasons: lower cost; fewer unknown factors; maintenance will be required anyway with both options; and considerably less interruption to traffic.
