First conclusion

The only real difference between

regular micro and color micro is

the color of the emulsion

Second conclusion

For market development,

colored micro-surfacing requires less

investment,

has almost no logistical constraints,

is more cost effective and

is significantly less risky.


14/30

Equipment

Only some small

alterations of availableslurry seal equipment

are required


15/30

Pigment addition

Pump and hydraulic system for pigment paste


16/30

For small applications

small scale micro surfacing machines (MiniMac)

Compared to the European market,

The US market is more focused on rustic

pavements to create a historical or natural

atmosphere/look.

Important learning experience


28/30

Conclusions

There are no technical constraints for a

successful introduction of colored micro-

surfacing in the US

Suitable micro equipment is available in the US

The US has numerous quarries offering

excellent sources of aggregate with a wide

variety of consistent colors.


29/30

Conclusions

US market is potentially strong for rustic

pavements

Marketing, marketing, Marketing.. key for further growth of this new micro

technology in the US and Canadian market
