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.

The concrete step barrier in the under construction M8 motorway in Ireland (August 2008) With effect from January 2005 and based primarily on safety grounds, the UK National Highways policy is that all new motorway schemes are to use high-containment concrete barriers in the central reserve. All existing motorways will introduce concrete ...
Real estate experts say these 6 curb appeal mistakes can lower your home's value. Attract buyers and avoid selling at a loss by following these tips.
A geometric design saved on construction costs and improved visibility with the intention to reduce the likelihood of traffic incidents. The geometric design of roads is the branch of highway engineering concerned with the positioning of the physical elements of the roadway according to standards and constraints. The basic objectives in ...
Curb appeal can be accomplished by any number of methods [2] including the installation of exterior decorations, re-painting, extensive attention to the landscaping. Several television programs have been created to explore ways for homeowners and building contractors to increase the curb appeal of their properties for a more profitable sale. [3 ...
Logo of Eurocode 2 An example of a concrete structure. In the Eurocode series of European standards (EN) related to construction, Eurocode 2: Design of concrete structures (abbreviated EN 1992 or, informally, EC 2) specifies technical rules for the design of concrete, reinforced concrete and prestressed concrete structures, using the limit state design philosophy.
The F-shape barrier is a concrete crash barrier, originally designed to divide lanes of traffic on a highway. It is a modification of the widely used Jersey barrier design, and is generally considered safer. [1] A parametric study, one that systematically varies the parameters, was done through computer simulations of barrier profiles labeled A ...
The sight distance, curvature and superelevation of the highway should follow the current edition of AASHTO's A Policy on Geometric Design of Highways and Streets for the chosen design speed. [4] Maximum grade: The maximum permissible vertical angle, or grade, along the highway is determined from terrain and design speed, [4] with up to 6% ...
