    Case Study On Pavement Maintainance Management System (PMMS) Of Urban Roads Network Using HDM-4 Model
    (AIKTC, 2020-05) Kazi, Tehsin; Sayeed, Guhagarkar Mubeen [14DCES58]; Kazi Danish Abdullah, Danish Abdullah [16DCES68]; Khan, Aslam Nasir [14CES15]; Pugavkar, Puja Dipak [17DCES50]
    The aim of the study is to develop Pavement Maintenance Management System (PMMS) for four road sections of urban road network (Patiala, Punjab, India) using Highway Development and Management (HDM-4) model. The HDM-4 provides a deterministic approach in data input and process data of existing road condition, traffic volume and pavement composition to predict road deterioration as per the urban road conditions in terms of International Roughness Index (IRI) value. This study presents the use of HDM- 4 model for the computation of optimum Maintenance and Rehabilitation (M&R) strategy for each road section and comparative study of scheduled and condition responsive M&R strategies. The results of present study will be useful for gaining better support for decision-makers for adequate and timely fund allocations for preservation of the urban road network.

    Pavement surface unevenness plays a pivotal role on roughness index of road which affects on riding comfort ability. Comfort ability refers to the degree of protection offered to vehicle occupants from uneven elements in the road surface. So, it is preferable to have a lower roughness index value for a better riding quality of road users. Roughness is generally defined as an expression of irregularities in the pavement surface which can be measured using different equipments like Merlin, Bump integrator, Profilometer etc. Among them Bump Integrator is quite simple and less time consuming in case of long road sections. A case study is conducted on low volume roads in West District in Tripura to determine roughness index (RI) using Bump Integrator at the standard speed of 32 km/h. But it becomes too tough to maintain the requisite standard speed throughout the road section. The speed of Bump Integrator (BI) has to lower or higher in some distinctive situations. So, it becomes necessary to convert these roughness index values of other speeds to the standard speed of 32 km/h. This paper highlights on that roughness index conversional model. Using SPSS (Statistical Package of Social Sciences) software a generalized equation is derived among the RI value at standard speed of 32 km/h and RI value at other speed conditions.

    Use of geotextile in road construction
    (AIKTC, 2021-05) Maheboob, Nadaf; Kazi, Tehsin; Khan, Mohd Rafique Raees Ahmed (17CE25); Shaikh, Mohd Irfan Shamsaad Alam (17CE35); Mansoori, Mohd Raees Rafique (17CE30)
    Geotextile have been successfully used for decades in the construction of roads. They fulfil almost all classical function like separation, protection, filtration, Drainage, sealing, and reinforcement. In recent time the scope of application has been extended significantly by the construction of road pavement. Field evidences indicate that geosynthetic reinforcements can improve pavement performance by avoiding cracking, rutting, potholes & by reducing deflection of road surface. Jute produced abundantly in India and may used in beneficially and abundantly with great efficacy for stabilization of soil and soil stabilization for week sub grade .Though there has been extremely limited but successful construction of roads.

    Use of recycled aggregates in rigid pavement
    (AIKTC, 2020-05) Kazi, Tehsin; Khan, Alfiya Mashid (16CE03); Dalwai Khan, Arbaz Afzal (16CE11); Solkar, Furqan Abdul Munaf (17DCE76); Suwarnadurgakar, Adnan Khalil (17DCE77)
    With the rapid rate of global urbanization and industrialization, there is an intense development around the globe. This call for a non-ending need of resources (both natural and artificial) and leaves behind huge piles of wastes. In developing countries like in India, generally C&D waste is not properly disposed in an unorganized manner thereby leading the problem of environmental issues. However these days globally research work is done regarding recycling and for devising new applications to make more sustainable environment. Concrete is the premier construction material across the world and the most widely used in all types of civil engineering works. In the past, aggregates were readily available at lower prices and qualities to suit all purposes. However, in recent years the uncontrolled quarrying and use of aggregates from natural resources has led to the depletion of primary aggregates and has created greater awareness of environmental protection. This paper explores a theme on the use for recycled concrete aggregates and highlights its potential use as aggregate in rigid pavement construction along with various techniques and applications involved in the process. The effect of adhered mortar on the properties of aggregate particle along with various methods proposed by different studies in the past for their removal is discussed in the study. Also established rules or specifications for incorporating recycled concrete aggregates by different countries are discussed in study.
