Abstract:
The valley of Kashmir is situated in the subtropical region but owing to its high altitude, it is cold. Due to encompassing mountain ranges, its seasons are marked by sudden changes. It attracts the western precipitation in winter mostly in the form of snowfall which covers the valley from December to March, January being the coldest month. The spring season which follows is mostly wet and the summer is humid and warm. The highland ranges prevent the western precipitation which is responsible for the snowfall in the valley from crossing over Ladakh and Gilgit region.
Due to cold temperature, the paving season remains limited to months of May, June, July and August. The problem associated with the construction of bituminous pavements in Kashmir is the control of viscosity of bituminous mixes during laying and compaction. Proper viscosity can be achieved by maintaining a proper temperature. The mixing temperature for 80/100 grade bitumen (which is recommended for Kashmir) should be in the range of 140 C – 155 C which can be easily controlled in the hot mix plants. Minimum laying and compacting temperatures of 115 C and 138 C respectively have to be ensured at the working site. If the bituminous mix is overheated at the mixing stage it loses the important volatiles resulting in loss of its basic binding property. Because of the large distance of hot mix plants from most of the working sites in Kashmir and generally low atmospheric temperatures it becomes difficult to maintain the minimum requisite laying and compacting temperatures. Sometimes the bituminous mix is overheated in the hot mix plants to ensure the minimum laying and compacting temperatures which is, as said already, very detrimental for the mix and the resulting pavement surface.
