1 NEOBALLAST SEEKING FOR THE BALLAST OF THE FUTURE

2 PROJECT CONSORTIUM NEOBALLAST BUDGET: ,92 PERIOD: SPANISH FOUNDED PROJECT PRODUCT DESIGN ACADEMIA FOUNDED IN 1891 RAILWAYS AS A CORE BUSINESS PRESENCE IN 23 COUNTRIES 48 R+D PROJECTS. (FP7- ECO INNOVATION LIFE+ - INNPACTO ETC.) MEMBER OF CLUSTER NETWORK BARCELONATECH (UPC). MANAGING FIVE RESEARCH INSTITUTES. HEAVILY INVOLVED IN RAILWAYS RESEARCH (PROF. A.LOPEZ PITA) CHEMICAL PRODUCTS SPECIFICATIONS & QA FOUNDED IN FACTORIES IN 5 CONTINENTS IN 31 DIFFERENT COUNTRIES 18 R&D LABORATORIES 12% OF THEIR RESOURCES AND 5% OF THE INVOICE IN R+D 57 R+D PROJECTS WHICH REPRESENTS 107 M IN COLLABORATION WITH 125 SPANISH ENTRERPRISES, 22 TECHNOLOGIES CENTRES AND 24 UNIVERSITIES LARGEST HIGH SPEED RAIL NETWORK IN EUROPE (3100 km)

4 INFRASTRUCTURE EVOLUTION RAILS GEOMETRY & GRADES FASTENINGS ELASTICITY SLEEPERS STRENGTH & DURABILITY AND BALLAST?.....

5 BALLAST. STATE OF THE ART UNDER AVOIDS TACKLING BALLAST ABOVE/OVER WEAKNESSES FILL IN PERFORMS AS A BLOCK SYSTEM JEOPARDISING BALLAST BENEFITS SUBSTITUTION VERY EXPENSIVE ALTERNATIVE WITH POOR ABRASION RESISTANCE

6 BALLASTED vs. SLAB TRACK Low inicial cost Easy to laid out Allows geometry restoration (tamping) High permeability Low maintenance cost Longer life expectancy Higher speeds permitted Higher tonnage capacity

7 FEATURES TO ENHANCE MAINTENACE COSTS N&V LIFESPAN RECYCLE FOULED BALLAST

8 NEOBALLAST FEATURES TO ENHANCE NEOBALLAST ACADEMIA SOLVING ENVIROMENTAL ISSUES MAIN GOAL Improve ballast properties in order to increase lifespan of ballast tracks and decrease the intervention level using a smart coating which reduces N&V as well.

9 NEOBALLAST IMPROVEMENTS TECHNICAL UPGRADES Increase friction angle and dilatancy High abrasion resistance (less fines) More energy dissipated (rubber contact) ACHIEVEMENTS Extended lifespan Less maintenance Improvement of N&V performance Preserved high permeability Increase of load capacity Fit for tamping Compatibility: recycled / precast ballast

10 PROJECT STAGES. Work in progress STATE OF THE ART. SPECS AND REQUIREMENTS DESIGN AND DEVELOPMENT OF IMPROVED BALLAST DIFFERENT GRANULOMETRIES BINDER PROPERTIES COATING METHOD

11 -15% PROJECT STAGES. Work in progress PERFORMANCE OF THE NEW MATERIAL. LABORATORY TESTS LOS ANGELES AND D&A TESTS Los Angeles (abrasion) Density and absorption Micro-Deval (abrasion) Magnesium sulfate soundness Impact resistance Direct shear FROM LA16 TO LA1 (UNALTERED EDGES AND GEOMETRY)

12 PROJECT STAGES. Next steps FULL SCALE TRIALSAND FIELD TESTING Full scale test (CEDEX 21x4x5 m cavity test) In situ test Finite Element Modelling ANALYSIS OF RESULTS. GUIDELINES. ADAPTATION ON STANDARDS CHALLENGES TO BE FACED FIRE PERFORMANCE OPTIMIZATION OF RUBBER GRANULARITY - INDUSTRIAL PRODUCTION

13 SUMMARIZING NEOBALLAST Decrease of ballast degradation. Recovery of end-of-life aggregates N&V reduction. Enviromentally friendly. Already patented

15 TRACK PROBLEMS & CURRENTLY SOLUTIONS GEOMETRY DEFECTS TAMPING LOAD DISTRIBUTION NEW BALLAST FOULED BALLAST CHANGE BALLAST LAYER 15-20% fine material (under 1,6 mm) Every 25 years

16 TRACK PROBLEMS & CURRENTLY SOLUTIONS N&V EMISSIONS Vehicles Catenary Wheel-Rail Tie-Ballast Ballast-Ballast NOISE REGULATION Acustic map in urban areas with more than hab. and more than trains/year ( Ley Española 37/2003 ) Acustic contamination in urban areas under db ( Llei 16/2002 Cataluña ) NOISE BARRIERS Increases 5-10 times the kilometer cost of the line High visual impact More construction time for the line

17 NEOBALLAST TECHNICAL DESCRIPTION OF THE PROJECT PRINCIPAL OBJETIVE Improve ballast properties in order to increase the life cicle of ballat tracks and decrease the intervention level utilizing a smart coating BALLAST SMART COATING NEOBALLAST + = Reutilization of recicled ballast or other curruntly unsuitables materials.

18 TRACK PROBLEMS & CURRENTLY SOLUTIONS VIBRATIONS Vibration induced noise UNDER BALLAST MATS & UNDER SLEEPERS PADS Structure security Increases 5-6 times the kilometer cost of the line Affect permeability More time to extend the line

19 PERFORMANCE & ENVIRONMENT ENHANCED RESISTANCE BEARING CAPACITY OF FUNDATION SOIL (HIGH SPEEDS LINES, A. López Pita) If ϕ grows Nγ grows higher resistance ENVIROMENTALLY FRIENDLY tn/year of NFU in Spain 4% of pneumatics go to landfills in Europe 38% used to generate energy CO2, SO2 and NO2 emisions 10 centuries untill a tire disappear in a dump
