Pavement management analysis of Hamilton County using HDM-4 & HPMA.

摘要

According to the 2009 ASCE Infrastructure Report Card, Tennessee roadways have received a B- due to lack of funding. This thesis focuses on the optimal utilization of available funds for Hamilton County using PMS. HDM-4 and HPMA are used to assess the existing pavement conditions and predict future conditions; estimate fuel consumption; calculate road agency costs and user costs; determine cost-effective maintenance treatment; and suggest optimum utilization of funds.;From this study, fuel consumption is higher at peak hours due to reduced traffic speeds. User cost is higher on the state route than the interstate due to stop-and-go motion. Road agency cost for the state route is four times higher than the interstate. Micro-surfacing treatment may cost less, but does not improve rut depth, while an overlay improves the roadway including structural cracking and rut depth. In Tennessee, HPMA cost-effective optimization analysis is available to adequately distribute the available funds.
