Reducing Greenhouse Gas Emissions Through Strategic Management of Highway Pavement Roughness
3.1 INTRODUCTION
The national pavement network is a key component of the transportation infrastructure that the modern US economy depends on for mobility and movement of goods. The vehicles that use the network are responsible for nearly a quarter of the US’s greenhouse gas (GHG) emissions [1].
