ROAD RECONSTRUCTION WITH ROADCEM






            To understand the way RoadCem works we have to take a look at the repetitive loads which are typical for roads
            when in use; assuming we have a cyclic dynamic loading which is acting through the asphalt to the road base




                                                           However it is possible to have these two attributes  within one material. Reinforced  concrete  is a good
                                                           example; It has a higher modulus  of elasticity than standard concrete,  and it is more  flexible. As we
                                                           know it is not suitable for  road  base construction  and it isn’t needed as RoadCem technology  achieves
                                                           both these requirements  in the following way:-


                                                           By  forming  needle  like  crystalline  growths  around  and  between  the  particles  being  stabilised  RoadCem
                                                           essentially  wraps  the  individual  particles  together  in  a  dense  woven  matrix;  this  is  far  stronger  than
                                                           conventional  cement  bonding  between  particles  which  is  based  on  the  individual  contact  points
                                                           between  adjacent  particles  being  ‘glued’  together  –  a  more  unstable  connection  leading  to  brittle
                                                           behaviour.


                                                           The  wrapping  effect  produced  by  the  inclusion  of  RoadCem is  far  more  effective  at  binding  soils
                                                           and  weaker  aggregates  than  traditional  cement  stabilisation,  enabling  higher  loads  to  be  managed
                                                           by  the  stabilised  material  with  much  lower  deformations  and  the  a  far  higher  average  dynamic
                                                           modulus  than  conventional  cement  stabilisation  alone.
