There ar many unresolved problems relating the preparation and use of waste tyre derived product like cut scrap tires particularly in fills and embankments. The foremost pressing unresolved issue is to see the chances of self ignition attributable to the exoergic reactions that might end in fireplace. Waste tyre utilization comes, particularly the thick fills ought to be additional closely monitored, probably by putting in temperature probes and gas sampling wells. Gas from such wells ought to be sporadically sampled and analyzed for future hazard free assurance. On the opposite hand, a scientific and careful analysis shall be allotted underneath variable conditions and temperatures to pinpoint underneath those conditions any instability or inconsistency can be expected. The findings from this type of studies would be terribly helpful in watching the soil condition throughout and when compaction.
Because of there’s wide range regarding the optimum particle size and form of the tyre shreds or chips which will be used; additional data is required on the essential physical properties of tyres per their particle form and size. The consequences or blending varied size shreds or chips at intervals and hill conjointly have to be compelled to be any evaluated in terms of resultant engineering properties, optimum gradation of shreds or chips, compaction and settlement behaviour, also as potential combustibility.
Another thought that warrants any investigation considerations the mixing of soil and tyre chips or shreds. Among the variables that require to be any investigated ar the consequences of assorted proportions of tyre chips and soil on the engineering properties of the resultant composites, particularly the majority density and compaction characteristics. The sort of soil is another variable which will influence the majority density and compaction characteristics of the tyre chip-soil blends. If potential, optimum proportions of tyre chips and soil ought to be known for various tyre particle sizes and/or soil varieties.
Lastly there’s presently little within the means of field internal control testing that’s being done throughout the development exploitation tyre chip or tyre shred hill. Besides visual examination on the movement and settlement of the waste tyre layers; there are no alternative physical check done at the positioning. However, any findings throughout the compaction stage won’t indicate the particular situation once the compacted surface is opened for traffic.
