DIRECTIONAL KERB AND KERB BASE

For better understanding and more information of Derectional Kerbs please refer to "ReflectiveDirectional Kerb and K2 kerbs".

The existing method of repairing and repainting the damaged kerbs is time consuming. It takes 20 days to replace and repaint a typical 1350 metres of the kerbs at one junction which the practices adopted by others in this industry in Singapore. To benchmark the re-instatement or replacement to the damaged kerbs, there were no best practices tobe considered as the industry generally relies on Land Transport Authority of Singapore forsuch specifications.

This innovative concept would incorporate incorporate coloured reflective white and black directiona kerbs. These kerbs would be interlocking thereby eliminating cementing. These kerbs would then be fitted into a precast interlocking element that would act as a base. As such such no cementing at site would be carried-out. All the units will be made in a factory and transported to the site for installation.

The following objective could be achieved by using Reflective Directional Kerbs with precast kerb base:

*  Minimise road or lane closures
* Clear and visible kerbs in all weather conditions
* Quick and easy method of replacing damaged kerbs
* Cost and time savings

Below are the design of the permanently coloured Directional Kerbs with Precast Kerb Base:
