Based on those questions and a review of literature, we are issuing this guidance to provide clarification to pavement preservation definitions.Preventive Maintenance is "a planned strategy of cost-effective treatments to an existing roadway system and its appurtenances that preserves the system, retards future deterioration, and maintains or improves the functional condition of the system (without significantly increasing the structural capacity)." Source: aashto Standing Committee.This is the true goal of pavement preservation, a goal in which the fhwa, through its partnership with States, local agencies, industry organizations, and other interested stakeholders, is committed to achieve.Pavement Rehabilitation consists of "structural enhancements that extend the service life of an existing pavement and/or improve its load carrying capacity.There are 219 lanes miles of arterial streets and 128 lane miles of local streets (each local street has two lanes and arterial streets have multiple lanes.)
