(3) In case of deep screening, assessment of ballast required for recoupment and providing standard section should be made by deep screening the ballast section to the full depth in a rail length for two to three sleepers at every V2 to 1 km. In this case screening is done under the sleepers as well.
Adjustable ballast cleaning screen to allow aggregate size setting from 5/8inch to 1inch for screening material. Distribute returned ballast to either side of the track in tangent or curved track. Regulate/plow returned ballast to fit within standard track crosssection (capable
12 the lateral movement of a railway sleeper attributable to the ballast shoulder, for a range of 13 shoulder widths and heights. During the tests, the deflection and resistance were measured 14 and photographs taken. Photographs were analyzed using a digital image correlation
This powder along with dust, sand ashes from locomotive form an impervious layer and prevent the ease flow of water through ballast. The ballast are constantly press in the formation. This reduces the quantity of the ballast and also the elasticity of the railway track is affected. The ballast is cleaned regularly by means of screening.
Shoulder, or ballast cleaners are complicated looking machines that perform a basic but very important task, keeping ballast free from debris and dirt so it can most efficiently drain water away from the track structure (ties and rails).
A firm foundation for railroad performance. ... Loram''s missioncritical shoulder ballast cleaning, undercutting and excavating maintenance systems, coupled with ditching and drainage solutions deliver strong ROI and benefits to the health and performance of any railroad. Our inspection services, experienced teams and track record of safety ...

Similar to the laboratory studies, a 40 cmwide ballast shoulder was implemented in the test track. The geogrid used in these tests was 4 m wide, and it was spread out along the required lengths as mentioned previously. Fig. 8 demonstrates the different parts of the test track along with the location of geogrids.

Ballast Regulating • Can be done manually ... without screening • With modern machines very high outputs are
Shoulder Ballast Cleaning Guidelines 6 How does Shoulder Ballast Cleaning work? • It removes fouled ballast or mud "plugs" at the ends of sleepers that hold water in the ballast profile. • Mudholes form in wet, fouled ballast where there are impacts on the rail surface or weak spots in the underlying formation.
depth≥850mm(under railway surface) Screening efficiency: The cleaned ballast returned to the shoulders shall not exceed 3% fines when operating at the rated capacity of 1200m 3 /h with initial ballast bed contamination less than 30% fines. And the usable ballast contained in the waste shall not exceed 5% in weight.
It also helps with drainage, so rain water can drain away rather than pooling, and with preventing vegetation growth, which could destabilise the track and be a hazard for anyone working on the railway. The ballast is packed up to, between and around the sleepers, with a ''shoulder'' of ballast piled up at either end to resist sidetoside ...
adequate lateral track stability with smaller ballast shoulder widths than those specified in Table [8] The resistance to buckling forces may be enhanced by the provision of a ballast shoulder surcharge (windrow). [9] Use of the guidelines in this Clause will provide a design ballast shoulder .
This is because as the ballast layer tends to deform, the grains are restrained by tension generated within the fibres. However, the biggest benefit in the tests carried out in the SRTF was obtained by reducing the slope at the edge of the mound of ballast on which the track sits (termed the "ballast shoulder").
Rail ballast typically sits on a layer of roadbase type material, ... is most important, since this ballast shoulder is, for the most part, the only thing restraining lateral movement of the track. ... In the case of ballast the test is used to calculate volumes required as material is mostly delivered to a project by rail .

Figures 61 through 67 show standard ballast shoulder widths and side slopes. In. finished or resurfaced track, the top of ballast may be up to 1 in. below the top of the tie, but never above. the top ...
A Loram shoulder ballast cleaning program ensures a healthy, robust railroad infrastructure maintained to deliver maximum ROI. Shoulder ballast cleaning consists of removing ballast at the end of the ties, separating and discarding fines and fouled ballast from reusable ballast and restoring the reusable ballast to the shoulder.
Shoulder Ballast Cleaner – Specific to SBC34 Warning You cannot undertake this activity in the rail corridor unless you have completed a pre work brief and work site protection plan. Reference should also be made to the Protocol for Entering the ARTC Rail Corridor and the Business Rules for Working in the ARTC Rail Corridor
Furthermore, track ballast that is completely fouled can not be corrected by shoulder cleaning. In such cases, it is necessary to replace the ballast altogether. One method of "replacing" ballast, if necessity demands, is to simply dump fresh ballast on the track, jack the whole track .
Jan 31, 2010· The fastenings shall not be covered with ballast. Jointed track shall be fully ballasted so that the vertical faces of the sleepers, timbers or bearers are not visible. Ballast shoulders for jointed track should be level with the top surface of the sleeper ends.
