These pavements are called perpetual pavements or long-term performance pavements (LTPP). When repairing pavement affected by fatigue cracking, the main cause of the distress should be determined. However, often the specific cause is fairly difficult to determine, and prevention is therefore correspondingly difficult.
In flexible pavements, the upper layer consists of asphalt concrete, that is a construction aggregate with a bituminous binder. The wearing course is typically placed on the binder course which is then laid on the base course , which is normally placed on the subbase , which rests on the subgrade .
Pavement engineering is a branch of civil engineering that uses engineering techniques to design and maintain flexible and rigid pavements. This includes streets and highways and involves knowledge of soils, hydraulics, and material properties. Pavement engineering involves new construction as well as rehabilitation and maintenance of existing ...

The results from the AASHO road test were used to develop a pavement design guide, first issued in 1961 as the AASHO Interim Guide for the Design of Rigid and Flexible Pavements, with major updates issued in 1972 and 1993. More recent versions of the guide are not primarily based on the results of the AASHO Road Test.
Highway engineering (also known as roadway engineering and street engineering) is a professional engineering discipline branching from the civil engineering subdiscipline of transportation engineering that involves the planning, design, construction, operation, and maintenance of roads, highways, streets, bridges, and tunnels to ensure safe and effective transportation of people and goods.
In landscape architecture, pavements are part of the hardscape and are used on sidewalks, road surfaces, patios, courtyards, etc. The term pavement comes from Latin pavimentum, meaning a floor beaten or rammed down, through Old French pavement. [5] The meaning of a beaten-down floor was obsolete before the word entered English. [6]
