Are Our Roads Prepared for Climate Change?

We have all recently seen what happens to the road infrastructure when Global Warming events like the recent floods in Germany, The Netherlands, Belgium, and Austria happen.


Whole road systems swept away by the fierce torrents of water.



In Central parts of Mexico flooding is an annual event. Traditional deep stone road base is always vulnerable to washout. So, roads in this region have for the last ten years have been constructed using RoadCem technology. Unaffected by the weather be it heat, ice and/or rain. The thermal neutrality and waterproof nature of RoadCem bound soil base, will with a tack course bind effectively directly to an asphalt running surface. To form a stiff elastic structure with excellent recovery attributes, to cope with the frequent repetitive loadings applied by the millions of axle passes for many years.

A UNESCO study in to RoadCem technology, calculated that over a twenty-year period cost savings of over 75% would easily be made, compared to traditional highway design. (See link below)

UNESCO Report

Constructing roads with RoadCem technology is far a more sustainable method, with large carbon savings. We must all presume that things are changing and that heatwaves and the potential for massive local downpours will only increase.

One thing that will not increase is our legacy of natural stone. Never have we quarried, crushed, and trucked such large quantities of stone about the country. Buildings and roads are nearly all built on foundation beds of crushed natural stone, why!
