    Experimental investigation of RAP modified asphalt binder and crushed RAP aggregates
    (AIKTC, 2018-05) Kazi, Tehsin A.; Kadir Ahmed, Abdul Qayum (12CE23); Shaikh, Asgar Ali Gaffar Ali (14CE54); Khan, Salman Mehboob (14CE31); Ansari, Tahir Ahmad Khurshid Ahmad (14CE11)
    With the increase of the environmental awareness of people and the cost for petroleum based Asphalt as the binder of asphalt concrete, use of RAP has been the common construction practice for several decades in some countries. Since it gives the better performance over other material. To stimulate the reasonable use of RAP, it is necessary to research the ageing behavior asphalt under high temperature and oxidative condition. RAP is the term that has been given to removed or reprocessed pavement materials that contain asphalt and aggregates. The study shows the physical characteristics of bitumen grade VG30 when mixed with RAP in various proportion i.e (10% , 20% , 30% , 40% , 50%) and the effects of these percentage on the physical characteristics like ( Penetration, Softening point, Ductility and Specific gravity) Study also shows the recycling of RAP material and to minimize the problem of waste disposal into landfill up to some extent. For the present study, the RAP was collected from Mumbai International Taxiway. The age of RAP is 8 years. The various test such as Crushing test, Impact test, Los Angeles Abrasion test and Shape test on crushed and virgin aggregates were also carried out. The summarizing results of RAP in various proportions with virgin bitumen and crushed aggregates are discussed.

    Intelligent traffic control system at intersection: Case study
    (AIKTC, 2021-05) Kazi, Tehsin A.; Shaikh, Mohamed Ishaque Rafiq (18DCE15); Qureshi, Mohammed Usama (17CE45); Shaikh, Salah Raisuddin (18DCE16); Chougule, SaifAli Shabbir (18DCE03)
    Traffic jam and accidents are one of the major problems in a densely populated cities, whereas population and number of running vehicles are much more than the road capacity. Due to traffic jam a substantial portion of working hours have to be left on streets which indirectly put adverse impact on economy and unavoidable road accident which results loss of lives. As the number of road users constantly increases, and resources provided by current infrastructures are limited. Traffic control system has become a very important issue. The main objective of this study is to reduce the accidents at the cross junction point. For doing this a microcontrolleror barricade is used with the help of sensor based technology which will make the drivers bound to follow the traffic rules by controlling traffic system that brings the result of decreasing the rate of accident, controlling crowd, lowering the tendency of road blocking etc. This approach can be applied in cross road junction.

    Navi mumbai international airport EIA report: Case study

    The dictionary meaning of the term ‘environment’ is a ‘surrounding’. It is derived from the English word ‘environ’ which means ‘to surround’ or to ‘encircle’. What constitute a surrounding? It is not very easy to Comprehend this term. It encompasses all external conditions influencing development or growth of people, animal, and/or plants. The external conditions are quite profound in the context of ‘environmentalism’. The basis for ‘environmentalism’ is the belief that environment rather than heredity is the main influence on a person’s behaviour and growth. It is a thought process which concerns about the environment and its protection from the adverse effects of all kinds of pollution and other human activities. Darwin’s Theory of evolution leading to the situation of the survival of the fittest is perhaps the best example of the environmentalism (Darwin 1859)

    Pavement evaluation and design of overlay
    (AIKTC, 2018-05) Kazi, Tehsin A.; Dayatar, Mohammad Sajid Aziz 15DCES66; Patel, Saqib MohdHanif 15DCES80; Qureshi, Mohd Subhan Mohd Miya 15DCES81
    In India, different types of pavement design have been observed. Most of the highways are having the flexible pavement. Pavement is designed to support the wheel load imposed on it from traffic moving over it. Additional stresses are also imposed by change in the climate. Pavement should be strong enough to resist the stresses and to distribute the external load. The study highlights the need of pavement evaluation and pavement evaluation measures for the road pavements of Road joining NH48 to NH548. Present study also includes the collection of required field data like soil subgrade data, existing pavement structure, traffic data, pavement surface condition and rebound deflection by using BBD technique and laboratory investigations, and finally on the basis of data analysis, design of extra width of road and overlay thickness of the road pavement and strengthening of the pavement has been discussed for the same road stretch. For road widening the existing traffic volume study carried out and compared with design standard volume as per IRC: 64-1990 guidelines and need of widening is justified. For structural evaluation the existing pavement condition has carried out by BBD technique and overlay design has carried out as per IRC: 81-1997 guidelines.

    Study on the performance of crumb rubber modified bitumen by varying the sizes of crumb rubber
    (AIKTC, 2017-04) Kazi, Tehsin A.; Ansari, Mohd. Hammaad (13CE05); Chaudhary, Abdul (11CE15); Choudhary, Mohd. Arshad (13CE13); Shaikh, Rehan (12CE55)
    The abundance and increase of waste tyre disposal is a serious problem that leads to environmental pollution. Crumb rubber obtained from shredding of those scrap tires has been proven to enhance the properties of plain bitumen since the 1840s. It can be used as cheap and environmentally friendly modification process to minimize the damage of pavement due to increase in service traffic density ,axle loading and low maintenance services which has deteriorated and subjected road structures to failure more rapidly. Use of crumb rubber leads to excellent pavement life, driving comfort and low maintenance . The rheology of CRMB depends on the internal factors such as crumb rubber quantity, type, particle size, source and pure bitumen composition , and external factors such as the mixing time, temperature, and also the mixing process(dry process or wet process). The present study aims in investigating the experimental performance of the bitumen modified with 15% by weight of crumb rubber varying its sizes. Four different categories of size of crumb rubber will be used , which are coarse(2.36 mm- 1.6 mm); medium size(1.6 mm- 1.18 mm); fine (1.18 mm- 600 μm); and superfine (600 μm- 300μm). Common laboratory tests will be performed on the modified bitumen using various sizes of crumb rubber and thus analyzed. Marshal stability method is used for mix design. Finally a comparative study is made among the modified bitumen samples using the various sizes of crumb rubber particles and the best size is suggested for the modification to obtain best results.
