STUDY ON POTHOLE FILLING METHODS AND TRUCKS
In 2016, nearly 1,50,000 deaths were caused by road accidents in India. Out of these, 2,424 deaths in road accidents were caused by potholes. Apart from deaths, they cause several accidents leading to major and minor injuries, and delay in travel time. Pothole is a failure in an asphalt pavement when there is water present in the underlying soil which weakens the supporting soil, and then traffic around affected area fatigues and breaks the asphalt surface. In this paper, methods which are used for filling potholes are discussed along with a concept of a modified pothole filling truck. This truck is equipped with a roller at its rear, and consists mixing blades for the aggregate and emulsified asphalt.
DESIGN AND ANALYSIS OF HANDICAPPED STEERING TRICYCLE
Conventional tricycles for handicapped require a lot of human effort to operate. They generally come with separate arrangements for providing motion and giving direction to the vehicle. These separate arrangements cause asymmetric use of hands and this results in discomfort of the rider. To alleviate this discomfort, a new arrangement which is mechanically more efficient than the conventional handicapped tricycle has been introduced, contains a single unit for providing motion and giving direction to the tricycle. Push and Pull motion of the steering results in forward and backward motion of the chair, while rotational motion of the same gives direction to the chair. In this paper, structural analysis is performed on the handicapped steering tricycle. Modelling is done on Solidworks 14 and ANSYS Workbench 15 is used to perform structural analysis.
