In addition, there are systems of roads maintained by the federal government and local counties. There are frequent overlaps between designations when different types of highways share the same stretch of pavement in concurrencies.
The Office of Materials Technology (OMT) which consists of the Executive Services area and eight divisions: Field Explorations, Engineering Geology, Pavement and Geotechnical, Asphalt Technology, Concrete Technology, Soils and Aggregate Technology, Structural Materials and Pavement Markings, and Materials Management.
This manual is the base bridge design manual that all DOTs use across the US. Manual for Assessing Safety Hardware (MASH), crash testing criteria for safety hardware devices for use on highways; it updates and replaces NCHRP Report 350. In addition to its publications, AASHTO performs or cooperates in research projects.
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]

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).
A pavement management system (PMS) is a planning tool used to aid pavement management decisions. PMS software programs model future pavement deterioration due to traffic and weather, and recommend maintenance and repairs to the road's pavement based on the type and age of the pavement and various measures of existing pavement quality.
