CAREFULLY DOES IT
As part of the ongoing £1 million programme of improvements to the road surface of Bristol’s Clifton Suspension Bridge, specialist road planning contractor, JET Plant have removed 120 tonnes of the existing asphalt surface.
Due to the 8 tonne maximum weight restriction on Bristol’s iconic Victorian bridge, two of the firm’s smallest planers, at just 350mm wide, were used at either end of the bridge. Not only did the JET Plant operators have to ensure that a 25m distance was kept between the two planers at all times, they also had to ensure that the metal reinforcement mesh covering the bridge deck remained untouched. Finally, just to make things even more challenging, the work was done at night, to minimise traffic disruption.
Managing Director of the Worcestershire firm, Sean Witheford commented, “This was undoubtedly one of the most difficult jobs we’ve done in a long time. It required a lot of planning to ensure the planers worked in a set sequence so as not to exceed the weight limit. We are fortunate to have very experienced operators who were able complete the job on time, whilst also complying with the bridge’s rigorous working conditions.”

PLANER PROVES ITS WORTH ON HIGH PRESSURE SITE
Specialist road planing contractor JET Plant planed out an amazing 270,000 m_ of asphalt on the M48 from the Severn Crossing to the M4 in just under 8 weeks.
JET Plant’s new state-of-the art, high-performance 2.1m cold planing machine, made light work of this mighty task – the largest contract undertaken by the company to date – enabling an average output of 30,000 m_ to be achieved per day.
Most of the work on this high pressure site was undertaken at night and in extremely tight working conditions. There was a particular emphasis on health and safety; the requirements included a three man crew, equipped with an intercom system to ensure good communications around the machine, and a banksman, all in appropriate PPE.
With a standard milling width of 2.10 m and high engine power, the machine is fully equipped for large-scale sites, delivering high output with maximum flexibility. With a planing depth of up to 320 mm, the entire pavement construction, from the wearing course down to the base course, can be removed in one single pass, saving time and ensuring high productivity.
Managing Director, Sean Witheford commented, “The 2.1m machine was ideal for this contract and with careful planning our very experienced operators were able to meet the output targets, completing the job on time, whilst also complying with the site’s rigorous working conditions.”
Based at Evesham in Worcestershire, JET Plant operate a fleet of 22 planers, with all operators CSCS, EPIC and NVQ 2 qualified, keeping JET Plant at the forefront of the UK road planing industry.

NEW ADDITIONS TO THE FLEET
In response to strong customer demand, JET Plant has added two new cold planers to their fleet – a Wirtgen 2.1m and a 500mm planer. This brings the fleet to a total of 21 planers, with all operators CSCS, EPIC and NVQ 2 qualified, keeping JET Plant at the forefront of the UK road planing industry.
The 2.1m machine, the second of its kind for JET Plant and the third 2m planer in the fleet, is a state-of-the art, high-performance planer mounted on crawler tracks. With a standard milling width of 2.10 m and high engine power, the machine is fully equipped for large-scale sites, delivering high output with maximum flexibility. Achieving a planing depth of up to 320 mm means that the entire pavement construction, from the wearing course down to the base course, can be removed in one single pass, saving time and ensuring high productivity.
By contrast, the 500mm cold milling machine, which works to a maximum depth of 160mm, is ideal on its own for small-scale repairs or working in conjunction with larger machines in the more confined and peripheral areas and around road fixtures. The truly versatile 500mm machine has an extremely small turning radius which allows planing right up to the edge of road fixtures, eliminating the need for manual reworking.
The machine operator can control the milling depth, as well as the longitudinal and cross slope of the planed surface with pin-point accuracy to produce a clean, straight and smooth milling edge. The texture of the milled surface permits an excellent bond between the existing base and the new pavement material.
Managing Director, Sean Witheford commented, “We have an excellent reputation for service and innovation which is second-to-none. Keeping a modern fleet ensures precision and reliability on site and all our operatives are trained to get the very best from the equipment. Continuous investment in the latest machinery ensures that we meet our customer’s high expectations of us.“

CASE STUDY
Client: Edmund Nuttall
Site Location: A465, Heads of the Valley, Abergavenny
Contract Duration: 6 Weeks
Completed : June 2007
The brief given to JET Plant Hire was to take up all the existing asphalt on the old carriageway which was soon to become redundant by the new road scheme. The plannings were then re-used by the main contractor on site, rather than bringing in virgin aggregates - a double environmental benefit as the redundant carriageway asphalt was not taken to landfill and the haulage of materials to and from site was eliminated.
The W100F cold milling machine proved ideal for the task, with its high output Deutz engine and ability to plane 320mm in one pass, it was capable of planning in excess of 500 tonnes in an 8 hour shift. Also, being relatively light weight and sitting on tracks, it was able to plane right down to the sub-base without any traction problems and fear of sinking into the granular material below.
Delivery to site with the W100FÕs own tipper and trailer meant JET Plant could react to the needs of the site requirements and travel from location to location quickly and efficiently as directed by the site engineers.
