1 Engineered Solution Provider in Geosynthetics GEOSYNTHETICS APPLICATIONS & IMPORTANCE OF PERFORMANCE RELATED SPECIFICATIONS By M. VENKATARAMAN
2 NEW CHALLENGES In recent years, while providing a solution, the Engineer has to face increased challenges: Various site constraints like space, alignments etc. Tight time schedules Ensure max. usage of local resources (Material & Manpower), hence Cost effective!! Least environment impact Long term performance & higher Cost benefit ratio over a larger period of time (Least maintenance cost)
3 SOLUTION!!! USE OF APPROPRIATE GEOSYNTHETIC MATERIALS OFFERS THE POSSIBILITY TO SOLVE OR DRASTICALLY REDUCE THE PROBLEMS
4 GEOSYNTHETICS CONCRETE & STEEL GEOSYNTHETICS

29 TECHNICAL SPECIFICATIONS Properties : Polymer Composition, Structure & Physical Properties Mechanical Properties Hydraulic Properties Survivability Installation Practices UV Resistance
30 TECHNICAL SPECIFICATIONS Present Scenario: For any application, the technical specification includes all the properties irrespective of the function to be satisfied It is significant to specify the properties essential for the function Eg: For Reinforcement application It is more relevant to specify long-term strength and strength at 2% and 5% strain rather than Ultimate Strength
31 TECHNICAL SPECIFICATIONS Dictates the exact materials and processes to be used in a project No guarantee that the best available product is delivered They focus on the Process and not on the Final Output (Performance)
32 TECHNICAL SPECIFICATIONS Properties Influencing Effective Performance of the Product FUNCTIONS Separation Filtration Drainage Reinforcement PROPERTIES AOS AOS & Permittivity AOS & In-Plane Permeability Tensile Strength, Secant Modulus
33 PERFORMANCE RELATED SPECIFICATIONS (PRS) Performance specifications describe how the finished product should perform over time It is the bridge between design, construction quality, and long-term product performance Specifications that use quantified quality characteristics and life cycle cost relationships correlated to product performance.
34 Performance Parameters Depends on the Product and the application Governing Factors PERFORMANCE RELATED SPECIFICATIONS (PRS) End Result Elements: - Bearing capacity, stability, settlements, cracking, etc., Functional Requirements: - Smoothness, friction, etc.,
35 PERFORMANCE RELATED SPECIFICATIONS Fundamental Requirements: Critical Quality Characteristics Measurable and tied to product performance Prediction Tools (modelling and databases) Verified, calibrated, validated, and made appropriate for local conditions Life Cycle Cost Analyses (LCCA) To compare the as-designed product section to the as-built section
36 Benefits PERFORMANCE RELATED SPECIFICATIONS Improved link between Design and Construction Improved and focused testing on characteristics related to performance Promoting best practices to improve quality Improving Flexibility, Efficiency and Value of the system
37 Benefits PERFORMANCE RELATED SPECIFICATIONS Adding private sector innovation Allow contractors more freedom to implement their own procedures, choose their own equipment, and conduct site-specific process control programs Transferring risk away from the owner
38 Barriers PERFORMANCE RELATED SPECIFICATIONS Determining good performance criteria and measures Potential impacts to contractors performance bonds A drastic change in corporate culture Openness and Trust Change of Industry mind set Focus on solution rather services Delivery driven by value not cost
39 WORLDWIDE SCENARIO Premier Institutes and Agencies implementing PRS FHWA AASHTO European Union UK DOT, California (Caltrans) Winconsin, DOT experienced 36% improvement in highway ride quality & 10% savings in LCC using PRS in Pavements
40 ROAD MAP TO THE FUTURE VISION Better translation of design and performance requirements into specifications MISSION Establish Performance Related Specifications
41 ROAD MAP TO THE FUTURE GOALS Identify relationships that link design and construction with product performance Develop and Implement Performance Specifications DRIVING FORCE Freedom to innovate with accountability to deliver
