History

Already in 1851 the first road was made in

MA construction in Potsdam

3


Production of MA(1934)

Laying MA manually (1934)

Transport in special vehicles - The asphalt is constantly in motion

Porous Mastic Asphalt (PMA)

young design

Further development of the mastic asphalt with an open pore

structure at the surface

Densely at the bottom of layer, open at the surface

Coarse aggregate determines the surface

Paving temperature 180 – 190 °C

By using a traditional paver

no recompaction

No gritting

Noise reduction >4 dB (A)

Production and paving

• Note the specific requirements for raw materials• Meet mix temperature requirements (max. 200 °C)• Carry out a test mixture• Installation of a trial field• no silo storage• Short transport distances• investigate influence of release agents


14


• paving temperature 180 to 190°C• Avoid stoppages• Easy to use roller (only static) no compression - only for

eveness of the surface• Rolling temperature should be about 130°C
