I built an engineered concrete block retaining wall at Lincoln's Tomb in Springfield, Illinois. 15,000 blocks, 12,000 tons of sand backfill. I built it per Illinois Department of Transportation (IDOT) design and specs. We make a pot full of money and it looks great twenty two years later.
Bituminous asphalt concrete, commonly called asphalt is not usually designed only for compressive strength. Portland Cement Concrete, often called simply cement, is designed for many qualities including compressive and flexural strenth. Asphalt is the bituminous material that binds the hot mix asphalt (HMA) together while Portland cement is what binds the aggregates together in concrete. Both have their place in modern pavement designs. Nothing to do with trucks but I felt like some more educating might be in order. Have fun with that my haters.
