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 and asset management, and many municipalities use it to measure the performance of their road infrastructure and their levels of service. It is a statistical measure and requires manual survey ...

Ride quality has been integrated into the department's highway construction procedures as a Standard Specification Item since 1993. The ride quality goal is to begin a pavement structure's performance period (see Chapter 2, Fig. 2-12) at a high level of smoothness, and maintain it at an acceptable level throughout the design life by ...

Road Standards and Paving Standards. ASTM's road and paving standards provide the specifications and test methods pertinent to the material, physical, mechanical, performance, and application requirements of road surfaces and pavements. These geotechnical surfaces are laid down on specified areas intended to sustain either or both foot and ...

Superior paving systems used for asphalt work make it easier to achieve a high level of ride quality. A very high standard of ride quality is required on high speed rural and urban roads with a speed limit in excess of 80 km/h for reasons of driver comfort, safety and to reduce road user costs and accelerated pavement wear and deterioration.

Swelling soils are responsible for pavement heaving, poor ride quality, and cracking in many areas of the southern and western United States.

The new European Standards for asphalt comprise two families of standards: the EN 13108 family of product and associated standards. the EN 12697 family of testing standards. These ENs (the UK versions of the ENs are designated 'BS EN' and are published by BSI) replace the current Part 1 of BS 49871, which addresses coated macadams, and Part ...

It is imperative that your asphalt is smooth and Andersen Asphalt & Striping is here to explain why. Pavement Ride Quality. Many people enjoy driving on a surface that has been freshly paved. It is like riding on glass. You would never want a freshly paved road to have an uneven surface as this creates bumps and a rocky ride as you drive down ...

Asphalt is a mixture of aggregates, bitumen and filler, used for constructing and maintaining roads, parking areas, ports and airport runways among others. There are various benefits to using asphalt for paving: 1. Smoothness / Ride Quality. Asphalt mixes provide a smoother pavement surface, thus reducing damages to the surface.
