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. [2]
Generally concrete pavements are more durable in warmer climates, and asphalt pavements are more resilient against cold weather. The joints in concrete pavement is another source of issue. In a certain type of road (concrete, asphalt or gravel), the thickness of layers and type of materials used in base, sub-base and pavement layer matters.
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.
Asphalt shingles on a home in Avalon, New Jersey. Two types of base materials are used to make asphalt shingles, organic and fiberglass.Both are made in a similar manner, with an asphalt-saturated base covered on one or both sides with asphalt or modified-asphalt, the exposed surface impregnated with slate, schist, quartz, vitrified brick, stone, [6] or ceramic granules, and the under-side ...
A deterioration model can help decision-makers to understand how fast the condition drops or violates a certain threshold. [5] Traditionally, most municipalities have been using deterioration curves for deterioration modeling. [5] Recently, more complex methods based on simulation, Markov models and machine learning models have been introduced.
The road test used large road user panels to establish the present serviceability rating (PSR) for each test section. Since panel ratings are expensive, a substitute key parameter present serviceability index (PSI) was established. The PSI is based on data on the road's longitudinal roughness, patchwork, rutting, and cracking. Later studies ...
The present serviceability index (PSI) is a pavement performance measure.Introduced by the American Association of State Highway and Transportation Officials (AASHTO), the PSI is one of the most widely used pavement performance indicators after pavement condition index (PCI) and international roughness index (IRI).
Like wheel-path fatigue cracking, poor drainage is a main cause of edge cracking, as it weakens the base, which hastens the deterioration of the pavement. [4] Water ponding (a buildup of water which can also be called puddling) happens more frequently near the edge than in the center of the road path, as roads are usually sloped to prevent in ...
