Title: Assessment of need for structural overlays using benkelman beam deflection method and improvement of the distressed pavement Authors: Mathakiya, Ashraf Mahmad Abstract: Road transportation constitutes a major portion in the overall transportation system. With the increase in traffic volume, there is observatory increase in the distress of pavement structure, which in turn causes excessive deterioration. With time, the failure goes on increasing gradually due to overloading of axles and significant variations in daily and seasonal temperature of pavement which is responsible for early development of distress symptoms like potholes, rutting, cracks, and undulations in bituminous surfacing. Thus the evaluation of the condition of pavement becomes quite necessary to choose appropriate improvement technique that can be implemented to improve the quality and strength of the pavement structure. This paper presents a case study on structural and functional evaluation of flexible pavement and analyzes the condition of the pavement which includes relevant data like soil sub grade data, existing pavement structure, traffic data, laboratory investigations, rebound deflection by using BBD technique and finally the design of the overall thickness of the pavement and overlay, required to strengthen the pavement. A detailed pavement condition survey is done on State Highway 17 (Doliya to Muli) and the road condition is evaluated structurally. The present study is evaluates the overlay thickness for State Highway 17 Doliya to Muli.

Title: Development of heterogeneous traffic noise level prediction model and Los at arterial road of nadiad city Authors: Mathakiya, Ashraf Mahmad Abstract: In developing countries like India, the nature of the composition of traffic is heterogeneous .A heterogeneous traffic flow consists of vehicles that have different sizes, speeds, vehicle spacing and operating characteristics. As a result of the widely varying speeds, vehicular dimensions, lack of lane discipline, honking becomes inevitable. Nadiad city has evidence a very rapid growth in urbanization which resulted in increased demand for transportation and at last it resulted in increased rate of noise pollution. Therefore, the traffic prediction models that are used for heterogeneous traffic conditions are nor applicable in heterogeneous traffic conditions. To increase the accuracy of noise prediction models, in depth understanding of heterogeneous traffic noise is required. Understanding the real traffic noise characteristic requires quantification of some of the basic traffic flow characteristics such as speed, flow, level of service, and density. In a given roadway, the noise level changes with density and level of service on the road. The noise prediction model will be developed based on various factors affecting noise.

Title: Retrofitting of Existing Building in “Sapar Industrial Area- Rajkot” Authors: Parekh, Mayank Abstract: Earthquake is considered as a most vulnerable activity for buildings. In this study, the existing building is considered which was not designed by consideration of earthquake, so as a part of a safety this building will be analysed by considering earthquake load and a new design will be given for retrofitting. The traditional method of seismic retrofitting is reviewed and their weak points are identified. Modern method and philosophies of retrofitting and energy dissipation devices are reviewed. The presentation is illustrated by case studies of actual buildings where traditional and innovative retrofitting methods have been applied. RC Jacketing of structural member is most suitable method for strengthening of building. Retrofitting is used to increase the load carrying capacity, increasing the current structure's stiffness, strength and ductility. The construction would therefore lead in secure and stable structures.

Title: To Develop Correlation between California Bearing Ratio (CBR) and Dynamic Cone Penetrometer (DCP) value for subgrade soil of selected stretches of Suredranagar District Authors: Mathakiya, Ashraf Abstract: There is lack of correlation between dynamic cone penetrometer (DCP) and California bearing ratio (CBR) for subgrade materials. This reasearch aims at determining a correlation equation between California bearing ratio (CBR) and dynamic cone penetrometer (DCP) for subgrade soils of surendranagar city in Gujarat allowing to economically and approprietly determine bearing capacity of subgrade soils in pavements design. The relationship developed in this reasearch considers subgrade materials behavior and largely saves time and cost of preliminary and detailed engineering works of road projects. Total 52 pits locations of surendranagar region of Gujarat state, where tests were conducted on in-service flexible pavement and also samples were collected for laboratory test. A series of DCP tests in field and CBR, proctor, Atterberg’s limit and grain size analysis tests in the laboratory has been conducted. Based on the field and laboratory test results relationship between DCP and CBR has been established. Power regression models were found to the best fit, which connecting soaked CBR with DPI shows strong correlation of a coefficient of determination (R2) of 0.876.
