Engineering Reports, Volume 8, Issue 1, January 2026.Open‐Graded Friction Course (OGFC) mixtures for flexible pavements. ABSTRACT Open‐Graded Friction Course (OGFC) mixtures in flexible pavements are known for their efficient drainage characteristics, but concerns exist regarding their structural weaknesses and short lifespans. This study investigates methods to improve the mechanical performance of OGFC

Elastic Properties of Concrete Incorporating Ogugu Lateritic Sand as Fine Aggregate
The Journal of Engineering, Volume 2026, Issue 1, January/December 2026.This study investigates the substitution of conventional fine aggregate with Ogugu lateritic sand in concrete grades 25 and 50, focusing on elastic behavior and strength development. The results show that laterized concrete achieves significant strength gains over time, with grade 25 compressive strength increasing from 14.11 N/mm2 at 3 days to 32.27 N/

Stabilisation of Sulfide‐Bearing Clays as a New Building Ground
European Journal of Soil Science, Volume 77, Issue 1, January–February 2026.ABSTRACT Fine‐grained, sulfide‐bearing marine clays are found along the Finnish coastline. When excavated and exposed to air, the sulfides within these soils react with oxygen to form sulfuric acid. Such soils are classified as hypersulfidic soils.
