Reduksi Emisi Gas Rumah Kaca Campuran Aspal Industri Konstruksi Jalan

Abstract

The construction industry plays an important role in the national economic development, however it also contributes to greenhouse gas (GHG) emitters. According to the BPS Indonesia regarding Final Energy Consumption referring to the 2009-2013 sector, the Industrial and Construction sector ranked first, thus the phenomenons of global warming, climate change, energy conservation and GHG emission reduction has become important issues in the construction industry including road contruction industry. This study is to determine the amount of GHG emissions from road construction industry at the production and the implementation of the asphalt pavement construction stages and also to determine the gap of mitigation results against the GHG emission benchmarks. To achieve these objectives, development of data activities and identification of key sources of GHG emissions for each stage are carried out. Equipment type, capacity,specifications, year of manufacture and fuel requirements were obtained from the survey. GHG emission estimates refer to the IPCC 2006 procedures and Bina Marga AHSP 2010. Aggregate heating at the production stage of HMA using diesel as a benchmark compared to aggregate heating: 1. HMA production using LPG 2. HMA production with 60% original aggregate + 40% RAP using Solar 3. HMA production with 60% original aggregate + 40% of RAP uses LPG 4. Production of warm asphalt mixture (WMA) uses Solar 5. Production of warm asphalt mixture (WMA) uses LPG. Furthermore, the study also carried out a reduction in the temperature of the asphalt mixture to the distance and travel time from the production location to the project location. achieved reduction of GHG emissions exceeding the target of 2.4%. Themost dominant aggregate heating process produces GHG emissions of 59.5% - 67.5% for all stages. Ranking of the largest emitters: AMP (aggregate heating.
