The existing road network surface in Ashar area are damaged and suffer from rutting. The Royal Commission of Al-Ula requested the road network to be improved and surface layer shall be designed to achieve smoothness surface and to reflect the surrounding area. To preserve the historical nature the recreation road is intended to have the colour and feel of the environment.
Ooms PMB was approved by the ultimate client Royal Commission of Ula and appointed by the contractor as the supplier of the synthetic pigmentable clear binder for the project. Based on the technical requirements for the asphalt surface layer, Ooms PMB proposed its synthetic clear binder Sealoflex® Color PG76 as the appropriate binder to withstand the tough climatic conditions in the Middle East.
In close cooperation with the client, contractor and engineer, a suitable mix design was developed. As a next step, a pilot project of 2 test sections of coloured asphalt was executed. In order to obtain the same colour as the environment, the client decided to use local crushed aggregates which resemble the colour of the surrounding area, without pigment. The Sealoflex Color® PG76 was manufactured in Ooms’ production facility in the Netherlands, and shipped to the Kingdom of Saudi Arabia in 3.800 steel drums in containers.
