Hemantha Raja Assistant professor, Department of Civil Engineering, KL University, Vaddeswaram, Andhra Pradesh, India ABSTRACT The idea of utilizing different fibers to enhance the conduct of pavement is not new in nowadays. The modern developments of fiber fortification began in the mid-196s. The fiber materials were presented and are ceaselessly being presented in the market as new applications for the pavement for example polyester fiber, asbestos fiber, glass fiber, polypropylene fiber, Carbon fiber, Cellulose fiber, etc. Among these distinctive fiber materials we have picked the glass fiber in light of the fact that the consequence of this review demonstrates that strengthening the bitumen clearing blend with glassfiber upgrades the general execution of the pavement. To study the effect of pavement when it is Partially replaced with glass fiber and how ductility and penetration value is varying by adding 1%,2%,3% glass fiber by replacing bitumen.the stability and flow values should be determined for nominal and modified mix by method by varying percentage of fibers.

International Journal of Civil Engineering and Technology, 8(4), 217, pp INTRODUCTION 1.1. General The massive development of highways everywhere through the world was going ahead at present century. A good roadway infrastructure is the foundation of a solid stable financial [1]. So main aim of the project is to increase the life period and stability of the flexible pavement editor@iaeme.com

2 K. Sri Harsha, M. Nikhil and K. Hemantha Raja As we know that the life period of the rigid pavement is more than flexible pavement But the cost of the rigid pavement is high and the cost of the flexible pavement is low [1].And the strength of the flexible pavement is low.so to increase the strength and the reduce the maintenance we are using glass fiber. Glass fiber that is used in the study was the recycled from waste glass as we know all over India some million tons of glass is disposed outside every year in the form of bottles and jars [11]. one answer for a part of the waste transfer issue is to reuse and utilize these material in the managing the developing issue of transfer of this material is an issue that requires coordination and duty by all gatherings development of highways however such an utilization ought not trade off the quality and execution of the roadway framework not bring about a domain issue [2]. 2. OBJECTIVES To study the effect of pavement when it is partially replaced with glass fiber. To study the ductility and penetration values for nominal and modified bitumen mix. To know the stability and flow values for nominal and modified bitumen mix by conducting Stability test. 3. MATERIALS USED 3.1. Aggregates Coarse aggregates from the major part of the pavement structure and this is the prime material used in pavement construction. Aggregates have to primarily bear load stress occurring on the roads and runway pavements and have also to resist abrasive action of traffic movement under dry and wet conditions, will used in the surface coarse of the pavement. The aggregates subjected in the pavement layers are subjected to impact due to heavy moving loads. Therefore aggregates used in pavement layers should have resistance to impact or toughness. The stone aggregates should retain the strength characteristics and should not disintegrate under adverse weather conditions including alternate wet dry and freeze thaw cycle. The properties of the aggregates are shown in the table-1. Table 1 Tests on aggregates S.No Name of test Trail 1 (%) Trail 2 (%) Trail 3 (%) (%) Specified values 1. Aggregate impact value [3] (strong) 2-3(good) Max Max.3 2. Aggregate Crushing Test [4] 3. Los Angeles Abrasion test [5] 4. Water absorption test [6] Specific gravity [6] Tests on Bituminous binders used in pavement construction works include both bitumen and tar. is a petroleum product obtained by the distillation of petroleum crude whereas road tar is obtained by the destructive distillation of coal or wood. Both bitumen and tar have similar appliance as both black in color, both these binder scan be used for pavement works. is used in surface coarse of pavement, this also used in the binder and base coarse of editor@iaeme.com

3 Partial Replacement of with Glass Fiber in Flexible Pavement flexible pavement to with stand relatively adverse conditions of traffic and climate.this materials also used in soil bitumen stabilization and to prepare sealer materials for filling the joints in cement concrete pavement. is available in variety of types. The grade of bitumen used in our project was 6/7.The properties of the bitumen are shown the table-2.

It is placed between the leveling layer or existing pavement and the new asphalt overlay, and becomes the hidden strength in the road. It retards reflective cracking by dissipating the horizontal stresses induced by the crack [7] Marshal Stability stability and flow values along with density; air voids in the, voids in the mineral aggregate, or voids filled with asphalt, or both, filled with asphalt are used for laboratory mix design and evaluation of asphalt mixtures [9] 12 1 % of passing LL Seive sizes Mix Figure 1 Gradation Graph Table 3 Marshal stability values for the Nominal mix MC editor@iaeme.com

The ductility value decreasing by increasing glass fiber. As glass fiber increases the softening point increases. The optimum binder for addition of glass fiber is 5.4%. The optimum binder for the nominal mix is 5.6%. The Maximum Stability value occurred at 5% of bitumen for 3% of glass fiber is 26.3KN. As compared to the nominal mix the stability value increasing. And the flow value is decreasing.
