Buildings and Concrete Roads
(Polymer Modified Bitumen)
This invention relates to the process for the preparation of a polymer and rubber based modified binder which is useful for the construction of roads catering to heavy traffic and also for the formation of airfields and surfacings, besides its use as binder for stress absorbing membrane (SAM) and stress absorbing membrane interlayer (SAMI) for sealing of cracks, preventive maintenance of flexible pavement and delaying reflective cracking. Modified Bitumen performs better than ordinary Bitumen in high rain fall area and in situation where the aggregates are prone to stripping.
- Improves resistance in cracking resulting in stronger and more durable overlays even in extreme climatic conditions.
- Reduces deformation on the roads even at temperatures of ( 50-70 degrees C)
- Polymer and Rubber based modifer binder extend life of pavement by 50-70% compared to conventional bitumen.
- PMB act as a multigrade bitumen and are economical when life cycle cost is taken into consideration.
(Crumb Rubber Modified Bitumen)
TIKI CRMB is a blend of selected grades of bitumen and crumb rubber modifier. The modifier restores the required visco-elastic balance of the Bitumen binder, which improves binder resistance to any form of permanent deformation while maintaining high resistance to fatigue, thermal and low temperature cracking. Using TIKI CRMB, the maintenance free life of pavement will increase one and half to two times as compared to roads built using unmodified neat bitumen binders. TIKI CRMB has good adhesion to different types of aggregates which therefore reduce rutting, cracking, deformations, etc. TIKI CRMB meets the performance- based specification of IRC: SP 53-2002.
- Excellent Resistance to Thermal and low temperature cracking.
- Superior resistance to any form to permanent deformation.
- Better adhesion between aggregate and binder.
- Overall improved performance in extreme climatic conditions.
- Higher fatigue life of mixes.
- Highly flexible and stability.
- Cost effective.
TIKI EMULSIFIED BITUMEN
IS : 8887 : 2004 (ISI MARKED)
TikiBitumen Emulsion is available as Anionic,Cationic and Nonionic types. Usually, it is the type of aggregate and climate that defines what type of Bitumen Emulsion be should used. Cationic Emulsion represents more than 95% of the world Consumption today.
The technology for the emulsion chemistry and type of application equipment make it the most logical class of emulsion to use, especially in case of tropical countries and countries with extreme climatic conditions.
The application advantages of Cationic Bitumen Emulsion depend on coalescence of the Bitumen droplets when they contact aggregate or road surfaces. Such coalescence is called breaking.Emulsions are broadly classified according to the speed with which they break when contacted with aggregate.
Paving Bitumen (Straight Grade)- shall be prepared by the distillation of suitable crude,petroleum oil without subsequent blending with other grades.The material shall be homogenous and shall not foam when heated to 175°C. No mineral matter other than naturally contained in the material shall be present.
TIKI ANTISTRIPPING AGENT
IS:14982/2001 & MORT&H REF. MANUAL
TIKI ANTISTRIPPING AGENT is a specially formulated compound for improvement of adhesion between Bitumen & Aggregates so as to avoid stripping of Bitumen on aggregates. It strengthens the bond between Bitumen & Aggregates which will not be dislodged by water.
Bitumen Primer -IS:217 & IRC:16
TIKI CUTBACK BITUMEN is low viscosity, cold applied bituminous primer. Cutback Bitumen is produced by fluxing bitumen with distillates of petroleum for use in road construction. A bituminous or an absorbent surface preparation before any super-imposed treatment construction. The objective of priming is to promote adhesion between the existing surface and the super-imposed treatment or construction.
ASPHALTOSEAL® has been used to provide a barrier between the concrete and the blacktop to minimize the differecnce between the temperature response of the two materials. Additionally, heavy traffic, such as loaded trucks, will cause a bow wave, analogous to that produced by a ship moving in water, on the surface of even a rigid concrete bridge-again, adversely affecting the surface quality of the deck.
TIKI EXJO FILLER
IS:1838 :PART I:1983 (ISI MARKED)
COMPRESSIBLE RESILIENT NON-EXTRUDIBLE EXPANSION JOINT FILLER
Engineers & Architects the world over are in accordance that because of seasonal variation in temperature,provision must be made to accommodate the expansion and contraction that invariably occurs in concrete structures such as construction of runways roads and long span building. Therefore to maintain the evenness of the surface and prevent it from cracking, thereby weakening the subgrade, provisions have been made to use correct Joint Filling and Sealing Compound so as to extend the life of these constructions.
TIKI SEALING COMPOUND
IS :1834I 2005 (ISI MARKED)
(HOT APPLIED SEALING COMPOUNDS FOR JOINT IN CONCRETE)
The important properties required in sealing compounds are that it can be applied without difficulty, are not unduly affected by temperature variation, adhere strongly to the concrete, and resist any tendency to flow out of the joint under hot weather conditions or loss of resiliency during cold weather conditions.
