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

MTV & Segregation

End and Start of Load Segregation:

Conical Augers Reblend End of Load & Start of Load Segregation

Rear Tilting Hopper Dumps Material on top or Re-mixing Augers

End of Load

Start of Load

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

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

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

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

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

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

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
