Static Analysis of Precast Concrete Piles using Resonance Moment–Displacement Method
Abstract: This paper presents the results of static analysis of circular precast single piles from critical buckling load by resonance moment-displacement approach. The circular precast single piles of different support conditions; pinned-pinned, fixed-fixed, and fixed-pinned were investigated. The critical buckling load was evaluated as the resonance moment-total deflection ratio. A computer program coded in basic language was invoked to carry out a composite analysis of single piles from critical buckling load …

An Investigation into the Mechanical and Strength Properties of Rubberized Asphalt Concrete
Abstract: In this study, the suitability of large rubber chunks from shredded tires as aggregates in cold mixes for road construction is investigated. The rubber was used as an additive to the asphalt binder. Thirty percent of rubber by weight was introduced into the binder at a higher temperature and the rubber was allowed to react with the binder. It was shown among other findings that for various particle sizes, the …

Stabilization using Waste plastic for Subgrade soil
Abstract: The Biggest challenge in a developing country like India is to build infrastructure system especially roads with limited financial source available. Use of local materials can considerably lower down the construction cost. If the stability of local soil is not adequate for supporting wheel loads, the properties are improved by soil stabilization techniques e.g. use of waste material obtained from industries or waste plastic in the subgrade soil, this can …
