INTRODUCTION
On the greater part of streets, ordinary bitumen performs agreeably. In any case, high activity power, expanding hub load and day by day and regular varieties in temperature of the asphalt prompt an early improvement of misery side effects like raveling, rutting, undulations, breaking, dying, and potholing of bituminous surfaces. Subsequently the heap bearing limits of the street is to be expanded. Adaptable asphalts (bitumen streets) involve the significant segment of all surfaced streets. In India, it is evaluated that more than 33 need kilometers of street exists and out of which of which around half is surfaced. Street transport has obtained prevailing position among the different methods of transportation framework because of its adaptability, way to-entryway administration, unwavering quality and speed. In India, street transport conveys near 90% of traveler movement and 70% of cargo transport. In India, dominant part of the asphalts is bituminous since they expend lesser beginning cost when contrasted and inflexible asphalts i.e. bond solid asphalts.

Literature Survey
Vasudevan et. al [2014], exhibited an investigation on the readiness of plastics squander -bitumen mix and its properties to discover the appropriateness of the mix for street development, was completed. A changed procedure was produced and the stone total was covered with liquid plastics and the plastics squander covered total (PCA) was utilized as the crude material for adaptable development. PCA demonstrated better restricting property. It had less wetting property. Its voids were substantially less. The example demonstrated higher Marshall Solidness esteem. The streets laid utilizing PCA are performing admirably. A point by point considered is exhibited.
Vasudevan, et al. [2015] likewise watched that the polymer mixed bitumen has better properties with respect to Softening point, Entrance point, Flexibility, Stripping Quality and Marshall Security esteem. Thus the mix can be utilized for laying adaptable asphalt. In this investigation both dry and wet procedures were utilized to get ready adjusted bituminous blends. In the wet procedure, the mixing was done by straightforwardly blending the destroyed polymer with hot bitumen at 160 deg. C. In the dry procedure, a novel system was utilized to utilize higher level of waste plastics in street development and utilizing this strategy a substitute technique was utilized. In this technique, the waste polymer was included the hot total (170deg.C). The polymer was covered over the total. Here the spreading was simple. The hot total was covered with polymer consistently. At that point the Bitumen was included. The blending of bitumen with polymer was occurring at the surface of the total. The temperature was around 155 -163 C. Both the polymer and bitumen were in the fluid state.
Vasudevan et al [2016] displayed that plastic waste comprising of convey sacks, containers and thermocoles can be utilized as a covering over total and this covered stone can be utilized for street development. By this procedure a street of 1 Km length and 3.375M width of single path can expends 10, 00000 convey sacks and the street quality is expanded by 100% and there is no pot opening arrangement. Infiltration was diminished to a low esteem and correspondingly the pliability. It has been construed that the utilization of higher rate (over 3%) of plastics in polymer altered bitumen isn't good. The paper additionally contemplates utilization of scrap elastic waste as bitumen modifier. Squander tires are powdered and the powder is Page: 381 mixed with bitumen (80/100) warmed to 100-120oC and blended at speed of 3000 rpm for 2-3 hours. This mix is utilized alongside plastic covered total. The blend polymer covered total and tire altered bitumen have indicated higher quality. The level of scrap elastic modifier in the blend changes from 1% to 5%.

Yadav et al [2017]
manages the improvement of changed fastener definitions from plastomer and elastomer write squander with a mean to limit non-biodegradable the post customer polymer squander and also ecological peril, to meet this target ten unique examples have been grabbed from a few sorts of waste to cover distinctive classifications of polymeric waste from the household, mechanical and in addition therapeutic waste. Changed cover definitions were at first portrayed according to the pertinent gauges (code of training) to determining their appropriateness for above said application. The physical properties of altered covers are inside as far as possible. Marshall Soundness, backhanded rigidity and crawl modulus conduct have been assessed and talked about in this examination to demonstrate their double advantages like waste minimization and appropriateness of such fasteners to be utilized for Sturdy Street.

The objective of this research is to determine the potential effect on the resilient modulus of asphalt mixtures of using granular Buton Rock Asphalt (BRA) modified binder. The indirect tensile stiffness modulus (ITSM) tests were performed to examine the resilient modulus of unmodified and BRA modified asphalt mixtures for dense graded aggregates of 10 mm (DG10) and 14 mm (DG14) based on standard AS-2891.13.1-1995. In these tests, three percentage of BRA natural binder, including 10%, 20% and 30% by total weight of asphalt binder, were chosen as a substitute for the base asphalt binder in the BRA modified asphalt mixtures, with the purpose of improving the resilient modulus values. According to the test results, the resilient modulus of BRA modified asphalt mixtures was higher as compared to the unmodified asphalt mixtures. A higher percentage of BRA modifier binder content resulted in a higher resilient modulus. Furthermore, the unmodified and BRA modified containing only 20% BRA modified binder of DG10 were tested under different conditions of temperature, rise time, and pulse period. The results indicated that the BRA modified asphalt mixtures containing 20% BRA modified binder were less sensitive to the changes in the temperature, traffic volume and loading frequency. In addition, the substitution of 20% BRA modifier binder reduced the effect of the rest period ratio and loading time on the resilient modulus of the asphalt mixtures.
Problem identification  Review of literature has revealed that E-waste causes adverse effects on the environment.  The eco-Friendly and reliable development for construction consists the use of non-conventional and different waste materials and recycling of waste material and decreasing the use of natural resources.  The growth in various types of industries together with population growth has resulted in enormous increase in economic activities world-wide.  Roads now have to be able to service large vehicular movements over diverse landscapes.
 It is very much desirable that lives of roads be long and requires minimal maintenance. Bitumen is most widely used for roads due to its characteristics, includingbetter binding property, etc. Such useful characteristics of bitumen can be further enhanced by adding modifiers to it.

Objective
The objectives of this study are as follows:  To analyze the engineering properties of modified bitumen using E-waste in varying percentage.

CONCLUSION
Marshal Stability values and flow value of bituminous mix are increased due to addition of E-Waste.
