Analysis of Bituminous Concrete Mixes Using H.D.P.E & Crumb Rubber as Admixtures

Abstract

Flexible pavements need more attention in selection of Resources and preparation of mixes now a day’s temperature is the main criteria which affect the mix quality, strength and durability. Rapid changes in temperature now a day’s big problem to face worst situations, Durability point is a big factor which affects the life period of the pavement surface and its components, Nominal mixes which consists of inert material doesn’t gives better Durability in severe traffic and climate conditions Today’s flexible pavements are Required to perform better as they are facing increased volume of traffic, increased loads and increased variations in daily or seasonal temperature over what has been Challenged in the past. In addition, the performance of bituminous roads is to be identified that they are poor in high drainage situations. Present scenario on using various additives for better drainage is not satisfying the expected results. However, the additive that is to be used for modification of mix or binder should satisfy both the strength, durability requirements as well as economical aspects. Plastics are using extensively in all over world and developing country like India. As these are non-biodegradable there is a major problem posed to the society with regard to the management of these solid wastes. Even, the reclaimed polyethylene originally made of HDPE has been observed to modify bitumen. In the present study, an attempt has been made to use HDPE and CRUMB RUBBER as admixtures in nominal bitumen mix to overcome the problem of resistance to weathering actions and repetitive wheel load
