- 2. PEDESTRIANS FOOTPATH MATERIALS FOR FOOTPATH CONSTRUCTION INTERLOCKING CONCRETE BLOCKS
- 3. PEDESTRIANS
- 4. Definition of pedestrian People 1.Who walk 2.Sit 3.Stand in public spaces 4.Use a mobility aid like walking stick 5. Use Crutches or wheelchair BE THEY CHILDREN,TEENAGERS,ADULTS,ELDERLY PERSONS,PERSONS WITH DISABILITIES,WORKERS,RESIDENTS,SHOPPERS,PEOPLE WATCHERS
- 5. FOOTPATH FOR PEDESTRIANS CONCEPTS 1.FOOTPATH SURFACE 2.FOOTPATH WIDTH 3.OBSTRUCTION 4.ENCROACHMENT 5.POTENTIAL FOR VEHICLE CONFLICT 6.CONTINUITY
- 7. Design standards for footpaths
- 8. • Clear walking zone-----1.8 m X 2.2 m (w and height) • Clear width ------ • for a single wheel chair—900mm • for a single wheel chair and a person –1200 mm • for two wheel chair-----1800mm • . dead width----1 m extra for shopping area • kerbs------max. 150 mm • surface quality • Cross falls—1:50 if absolutely necessary for drainage purpose • Service covers • Pedestrians guardrails. • Continuity and consistency

- 11. Interlocking concrete block SOME APPLICATIONS 1.Footpath and side-walks 11.Roads in high altitude area 2.Cycle track 12.Urban section highway 3.Village roads through villages 13.Road repairs during monsoon 4.Fuel stations 14.Residenttial streets 5.Highway rest areas 15. Car parking 6.Toll plaza 16.City streets 7.Industrial floors 17.Port wharf and roads 8.Bus depot 18.intersections 9.Truck park area 19.Container depots 10.Approaches to railway level crossing
- 12. SOME ADVANTAGES • HIGH QUALITY DUE TO MANUFACTURING IN FACTORY • IT RESTRICTS THE SPEED LIMITS • SKID RESISTANT • IDEAL FOR INTERSECTION • THE DIGGING AND REINSTATEMENT EASY • NOT AFFECTED BY SPILLAGE OF VEHICLE OIL • MAINTERNANCE COST LOW • NO CURING NEEDED • CONSTRUCTION IS EASY
- 13. LIMITATIONS •Can not be used in high speed traffic •Riding quality is not good •More noise •Very good drainage needed
- 14. DIMENSIONS TOP SURFACE AREA OF INTERLOCKING:- 5000 TO 60000 SQ.MM 1<MEAN LENGTH/MEAN WIDTH<3 LENGTH/THICKNESS>OR=4 THICKNESS BETWEEN 60 MM TO 140 MM
- 15. TYPES OF BLOCKS • Interlocking can be placed horizontally and vertically Horizontally placed vertically placed
- 16. Interlocking can also be grouped in three categories
- 18. PROCESS OF CONATRUCTION AND LAYIONG •SAND BEDDING AND JOINTING A course sand bed 20mm-40mm, joints 2 to 4 mm wide and filled with fine sand •BASE AND SUBBASE LAYERS sub base-GSB and drainage layer base -soil-cement ,lean concrete or WMM •EDGE RESTRAINT BLOCKS compresive strength >30 Mpa and flexural strength >3.8 MPa
- 19. COURSE SAND FOR BEDDING IS SEIVE % PASSING 9.52MM 100 4.75 MM 95-100 2.36 MM 80-100 1.18 MM 50-95 600 MICRON 25-60 300 MICRON 10-30 150 MICRON 0-15 75 MICRON 0-10
- 20. FINE SAND FOR JOINT FILLING IS SEIVE % PASSING 2.36MM 100 1.18 MM 90-100 600 MM 60-90 300 MM 30-60 150 MICRON 15-30 75 MICRON 10-30
