Optimization For The Allocation Of Funds For Pavement Maintenance In Pavement Management Systems, Armando Ramirez
Optimization For The Allocation Of Funds For Pavement Maintenance In Pavement Management Systems, Armando Ramirez
Open Access Theses & Dissertations
Pavement maintenance and rehabilitation are critical and costly elements for highway agencies. A challenge for transportation agencies is to preserve roadways in an appropriate condition and extend the pavement service life while maintaining the safety and satisfaction of its users, and maximize the benefits obtained by the repair investments. Pavement maintenance programming is increasing in complexity due to limited resources and increments in traffic and population. Management decisions are usually based on personal judgment by pavement managers and sometimes those decisions are not even supported by previous experience. Research shows that optimization methods can produce significant benefits when transportation agencies …

A Tool To Improve And Preserve Flexible Pavement At Intersections, Carlos Jesus Solis
Open Access Theses & Dissertations
Rural intersections originally constructed with thin untreated flexible base and hot mix or a two-course surface treatment tend to experience severe pushing, shoving and rutting. These failures cause an extremely rough surface that can cause damage to small vehicles and potentially cause motorists to lose control of their vehicles. These distresses almost always result in complete failure of the existing pavement that must be repaired several times during the life of the roadway by maintenance forces. In most cases, pavements constructed with the same materials and cross-sections adjacent to the intersection perform adequately.
The sources of and solutions for failure …
