New Concrete Road Joint Method Promises Crack-Free Pavement
A British road engineer introduces a method to lay concrete in alternating portions, allowing set sections before filling gaps to create joints. The approach prevents cracks at freshly finished edges and uses angled joints to distribute weight, aided by reinforcements across joints to strengthen the slabs. Aluminum alloys are advancing in aviation and machinery, with seven studies from the National Physical Laboratory backing promising new materials for engines, rolling stock, and steam power.
