The Project Emission Estimator (PE2) is for benchmarking life cycle emission
estimates associated with construction maintenance and use of a roadway.
Generalized Roadway Speed:
Build Life Cycle
Use this form to construct and benchmark pavement life cycles. Life cycles are
defined in terms of interventions (maintenance and rehabilitation jobs), with
the initial job determining the initial roadway construction type (materials,
batch plant, and hauling/construction equipment) and the associated work zone
emissions in year 1. Choices are limited to the reconstruction, rehabilitation,
and maintenance job types investigated by researchers at Michigan Technological
