The pavement condition index (PCI) is a numerical index between 0 and 100, which is used to indicate the general condition of a pavement section.The PCI is widely used in transportation civil engineering [1] and asset management, and many municipalities use it to measure the performance of their road infrastructure and their levels of service.

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.
[1] [2] The health of pavement is assessed using different performance indicators. Some of the most well-known performance indicators are Pavement Condition Index (PCI), International Roughness Index (IRI) and Present Serviceability Index (PSI), [3] [4] but sometimes a single distress such as rutting or the extent of crack is used.
Among the construction trades, in most industrialized countries, each has a distinct 2-5 year craft apprenticeship education and usually once started a worker remains in a single craft and progresses through ranks of skill for the duration of their career (pre-apprentice, apprentice, and journeyman; some countries include a post-journeyman ...
The IRI is used in managing pavement assets, as well as sometimes in evaluating new construction to determine bonus/penalty payments for contractors or for identifying specific locations where repairs or improvements (e.g., grinding or resurfacing) are recommended.
The PASER scale is a 1-10 rating system for road pavement condition developed by the University of Wisconsin-Madison Transportation Information Center. PASER uses visual inspection to evaluate pavement surface conditions. When assessed correctly, PASER ratings provide a basis for comparing the quality of roadway segments. [1]
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.
The EPC contractor coordinates all design, procurement and construction work and ensures that the whole project is completed as required and in time. They may or may not undertake actual site work. EPC companies are often used in large-scale projects, such as power plants, refineries, chemical processing facilities, infrastructure projects, and ...
