14 Bitumen - An introduction LAST RESIDUE OF CRUDE OIL TREATED TO PRODUCE BITUMEN.USED IN BUILDING AND PAVING SINCE ANCIENT TIMES.OLDEST ADHESIVE KNOWN TO MAN.USED IN 3500 B.C. AS MORTAR FOR BUILDING STONES AND PAVING BLOCKS IN MESOPOTAMIA.USED FOR WATER TIGHTENING OF RESERVOIRS, CANALS, BATHING POOLS & EMBANKMENTS OF RIVERS IN INDUS VALLEY.
15 Bitumen - An introduction (Contd.) Streets of Babylon constructed in 2000 B.C. still in good shape.Used for Mummification in 300 B.C.Rock Asphalt used for flooring/sidewalks in France in 1800 A.D.First road surfacing done in New Jersey in 1870 A.D.From 1900 onwards Bitumen produced from Refineries being used extensively.
17 Production Process Produced by fractional distillation of Crude oil. Crude Oil heated to 300 – 350OC in distillation column. Lighter fractions separated at different column heights. Bottom product called long residue.Long residue heated upto 450OC in Vacuum distillation column. Bottom residue (short residue) used for manufacturing Bitumen.Hot air is blown through short residue OR blended with superior quality bottom products to achieve desired consistency / penetration.
18 Advantages of Bituminous Roads Initial saving : fast construction + low cost.Ageless – rehabilitation is inexpensive.Stage Construction - in ribbons, not in slabs.Safe: High skid resistance + Good VisibilityBetter riding quality Less wear & tear of vehicle, Low noise while cruisingCan be fully recycled.
19 Engineering Properties of Bitumen A visco-elastic material : Deformation under stress a function of temperature & loading time.At high temperature & loading it behaves as viscous liquids, whereas at very low temperature or low loading it behaves as elastic solids.In the intermediate range of temperatures / pressure, more typical of the conditions in road service, bitumen has visco-elastic behaviour.
21 Composition of Bitumen Chemical composition depends on origin of Crude Oil and refining process.Chemical composition is extremely complex. Astronomically large number of Molecules with different chemical structures. Not feasible to attempt a complete analysis of Bitumen.Elemental composition of Bitumen provides little information of the types of molecular structure present in Bitumen.

30 Selection of Grade of Bitumen Choice of Bitumen is based onClimatic Conditions - Maximum & Minimum temperature & rainfall.Intensity of Traffic - Number of vehicles per day & axle load of vehicles.
31 Applications of 80/100 Grade Less viscous grade.Used in all climatic conditions.Suited for traffic load of less that commercial vehicles/day.Better suited for high altitude/snow bound regions irrespective of traffic intensity.
32 Applications of 60/70 Grade More viscous grade. Higher softening point.Suited for traffic intensity of more than commercial vehicles/ day.Can withstand heavier axle loads.Suited for areas where difference between min. & max. temp. is more than 25 o C.Reduced stripping of Bitumen from Aggregate in presence of water.Better suited for highways, expressways & urban roads.
33 Applications of 30/40 Grade Suited for traffic intensity of more than 1500 commercial vehicles/ day.Suited for areas where difference between min. & max. temp. is less than 25 o C.Used in metropolitan areas / airport runways.

42 What is Crumb Rubber Modified Bitumen? Crumb Rubber Modified Bitumen is Conventional Bitumen with treated Crumb Rubber Additive at high temperature which results inLower susceptibility to temp. variationHigher resistance to deformation at high temperatureBetter Age Resistance PropertiesHigher Fatigue Life of MixesBetter Adhesion Properties
43 Why Treat Crumb Rubber? Be compatible with Bitumen. Blend with Bitumen properly & thoroughly.Improve temperature resistance of Bitumen.Resist degradation of Bituminous mix.Be capable of being processed by conventional mixing plants and laying machinery.Produce coating viscosity at application temp.Maintain premium properties during storage,application and in service.Be cost-effective considering life cycle cost.

45 Circular Test track study conducted by Highway Research Station, Chennai
46 Tests conducted in Circular Test Track Study Surface EvaluationSkid resistanceTexture depthDepletion values
47 STUDY RESULTCRMB mixes indicate better resistance to deformation at high temperature times higher values of stability, Marshall quotient and stiffness modulus.Higher indirect tensile strength and stiffness modulus - better resistance to cracking in structural layers.Modified mixes in structural layers take higher traffic stresses due to higher values of stiffness modulus.Tensile strength ratio before and after conditioning in water is higher - superior resistance to moisture damage.
48 CIRCULAR TEST TRACK STUDY CONCLUSION The Highways Research Station has opined that the performance of modified bitumen stretch improves by 1.7 times than the conventional bitumen stretch.
