It’s a liquid asphalt surface treatment with a thin layer of aggregate placed at a thickness of around 0.5 inches or less. BSTs are normally used on pavements with lower traffic volumes. Types of Bituminous Surface Treatments 1. Single Surface Treatment The bituminous […]

But it can be minimized by proper planning for construction practices, compaction methods, and startup procedures. […]

These joints are formed when a new lane of hot mix asphalt pavement is placed adjacent to a previously placed lane. An improperly constructed longitudinal joint forms the weakest link threatening the whole pavement system. This article discusses the various techniques used to […]

Asphalt pavement is made of aggregates, sand, additives, and asphalt and is laid for the construction of driveways, parking lots, roadways, etc. Based on the variations in asphalt used in pavement design, there are several types of asphalt pavements. The five most common […]
