What Is Micro-Surfacing? Micro-surfacing is a modified form of slurry surfacing designed for relatively rapid setting and improved performance under traffic. The treatment uses a carefully proportioned mixture of aggregate, …

Road rutting is a common form of pavement distress caused by permanent deformation along vehicle wheel paths. It is particularly common on roads carrying heavy commercial traffic, especially when pavement …

Utility trenching is an important construction method in urban infrastructure projects, where underground networks have to be installed beneath roads, footpaths, public spaces and developed areas. Water supply pipelines, sewerage …

Road construction in waterlogged areas presents a different set of challenges compared with projects on well-drained and stable ground. High groundwater levels, saturated soils, poor bearing capacity, excessive settlement and …

Highway shoulders are constructed along the edges of the carriageway to provide lateral support to the pavement, accommodate stopped or disabled vehicles, improve road safety and assist surface-water drainage. Depending …

What Is Perpetual Pavement? Perpetual pavement is a multi-layer flexible pavement structure designed for a very long service life. Its design philosophy is based on controlling the two major structural …

Cut-and-fill construction is a fundamental earthwork method used in highway projects to create a suitable formation level for road pavement. The method involves excavating soil or rock from elevated areas, …

Road construction over weak soil presents engineering challenges because the subgrade may not have sufficient strength or stiffness to support construction traffic and long-term pavement loads. Soft clay, loose silt, …

Road underpasses are grade-separated structures that allow vehicles, pedestrians or other traffic to pass below an existing road, railway line or infrastructure corridor. They are used to reduce traffic conflicts, …

Road infrastructure is expected to support increasing traffic volumes, heavier axle loads, and changing climatic conditions while remaining cost-effective throughout its service life. Traditional flexible (asphalt) and rigid (concrete) pavements …
