42 MTV & Segregation Why MTV (Material Transfer Vehicle): 1. Provide Non Contact Continuous Paving Receive the material from the truck & Deliver to the paver without stopping Provide adequate surge for Truck Exchange Eliminate the Truck bumping the Paver 2. Ensure Material Consistency Re-mix Segregated material (Gradation & Thermal) in the Truck Bed End / Start of Load & Segregated Mix that Rolled to the side of the bed Crust on top of the truck bed and along the sides

43 MTV & Segregation End and Start of Load Segregation: Conical Augers Reblend End of Load & Start of Load Segregation End of Load Rear Tilting Hopper Dumps Material on top or Re-mixing Augers Start of Load

44 MTV & Segregation Segregated Material along the Side wall of the Truck Bed Segregated Stones gather to the outside of the hopper Re-blends as the variable volume augers moves the material to the belt Start of Load

45 MTV & Segregation Thermal Segregation in Truck Bed Crust from Hauling Re-blends as the material travels From MTV Hopper / Belts Through the Insert Grate system Baffles in the insert Finally through the Paver System

46 MTV & Segregation MTV Don t Prevent Segregation in the Hopper Insert Avoid Sloping Heap - Larger stones tends to rolled to the insert wall Sloping walls leads segregated stones to edge of conveyor tunnel The segregated stones placed as it reaches the bearing hanger End of Insert Insert wall

47 MTV & Segregation b) Segregation Created as the Tractor Delivers Material to the Screed (Not prevented by MTV) Could occur at Several Location along the width of the mat Leads to mostly Longitudinal Cracking Center Line & wheel path Wheel path

48 MTV & Segregation Typical Failure Modes: Longitudinal Cracking Centerline Wheel Path from edge of conveyor and edge on mainframe

49 MTV & Segregation Quick Review of NCHRP Report 441.A Detailed Study of Segregation Sponsored by AASHTO (American Association of State Highway and Transportation Officials) In cooperation with FHWA

50 MTV & Segregation Alabama Failure Modes: Longitudinal Cracking

51 MTV & Segregation Washington State Failure Modes: Longitudinal Cracking

52 MTV & Segregation Minnesota Failure Modes: Longitudinal Cracking

53 MTV & Segregation Texas Failure Modes: Longitudinal Cracking

54 MTV & Segregation b) Segregation Created as Tractor Delivers Material to Screed: A Center Line, Under Auger Box Difficulty in feeding under the auger box Large stones gather to the center B At the edge of the Tunnel Large stones gathering at edge of Tunnel C At the Edge of Fenders / Main Screed Restricted flow at auger bearing hanger Change of Flow at Tractor & Main screed Edge D At the Endgate / Joint When Material is forced to flow to End Gate

55 MTV & Segregation b) Segregation Created as Tractor Delivers Material to Screed Features that reduce Segregation as Tractor delivers to screed 1. Independent Auger and Conveyor Drive & Controls Material Delivery 2. Auger Extensions beyond Bearing Hanger 3. Reverse flights at Drive Box 4. Material Chutes under conveyor tunnels 5. Proper Auger & Tunnel Extensions when Paving Wide Material Deliver wide
