Application | Advantages | Disadvantages |
---|---|---|
Asphalt binder modifier |
– Enhances rheological properties (e.g., increased stiffness, elasticity, deformation resistance) – Improves aging resistance and temperature sensitivity – Reduces VOC emissions compared to conventional petroleum-based binders |
– May have negative effects on low-temperature performance at high biochar contents – Potential variability in biochar properties depending on feedstock and production conditions |
Asphalt mixture additive |
– Increases rutting resistance and resilient modulus – Enhances moisture resistance, particularly at lower biochar contents – Improves cracking resistance at optimal biochar content – Reduces VOC and GHG emissions compared to conventional mixtures |
– May reduce moisture susceptibility at high biochar contents – Cracking resistance may decrease at high biochar contents – Potential variability in biochar properties depending on feedstock and production conditions |
Stormwater filter material |
– High surface area and porosity for adsorbing pollutants – Renewable and cost-effective compared to other filter materials – Contributes to carbon sequestration and emission reduction |
– Long-term performance and durability under field conditions need further investigation – Potential clogging and reduction in permeability over time |
