Choosing between macadam and asphalt depends on various factors, including: Budget: If initial costs are a major concern, macadam may be more appealing. Aesthetics: Consider whether you prefer the rustic look of macadam or the sleek appearance of asphalt. Maintenance: Think about the time and money you're willing to invest in upkeep.
DBM pavement is commonly used as a base course layer in road construction. Bituminous Macadam (BM) Pavement: BM pavement is similar to DBM pavement but has a lower bitumen content. It consists of multiple layers of crushed stone aggregates bound together with bitumen. BM pavement is commonly used as a base course or binder course layer.
Maintaining a macadam pavement is not difficult. It conceals oil spills better than asphalt and concrete driveways, and it's beautiful finish lasts even if it is not treated on a regular basis. Furthermore, a macadam pavement does not need frequent seal coating, which is often performed every two or three years on asphalt driveways. The only ...
