Pavement Engineering

Posted on by A F

Highway, Bridge and Street Construction
Pavement engineering is a branch of civil engineering that uses engineering techniques to design and maintain flexible (asphalt) and rigid (concrete) 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 pavements.

Maintenance often involves using engineering judgment to make maintenance repairs with the highest long-term benefit and lowest cost.

The Pavement Condition Index (PCI) is an example of an engineering approach applied to existing pavements. The PCI was developed by the United States Army Corps of Engineers.

Another example is the use of a falling weight deflectometer (FWD) to non-destructively test existing pavements. Calculation of pavement layer strengths can be performed from the resulting deflection data. The two methods – empirical or mechanistic is used to determine pavement layer thicknesses.
