DID YOU KNOW?

 

The chipseal method is a Kiwi invention. It was developed in 1935 by Levin-born Frederick Melrose Horowhenua Hanson, a maverick, decorated veteran of both world wars who rose to become Commissioner of Public Works. In 1935, while working for the Government, he perfected the scientific approach to laying chipseal, offering a way to build affordable roads in a young, agricultural country with a small population. The ministry that Hanson headed later became part of Downer, Road Science’s parent company.

“The Road Science innovation has delivered a huge benefit in terms of the road having a longer life … it’s all about sustainability and getting the most out of existing infrastructure,”

Veenay Rambisheswar, Manager Programme & Development Services @ Auckland Transport.
