A conceptual study on the formulation of a permeable reactive pavement with activated carbon additives for controlling the fate of non-point source environmental organic contaminants.

摘要: Abstract To take advantage of the road pavement network where non-point source (NPS) pollution such as benzene, toluene, ethyl-benzene, and xylene (BTEX) from vehicle traffic exhaust via wet dry atmospheric deposition occurs, asphalt may be used a media to control NPS pollution. An experiment prepare an adsorptive porous reactive (PRP) was initiated explore potential reduce environmental The PRP prepared studied follows: various activated carbons (AC) were initially screened determine if they suitable additive in mixture; mixtures selected AC incorporated with design concrete (PAC) produce PRP, formulations tested ensure that comply required specifications; qualified specimens subsequently their adsorption capacity for BTEX aqueous solution, compared conventional PAC. PRP08 PRP16 samples, named 0.8% 1.6% (by wt. formulation), exhibited low drain-down abrasion loss also met all regulated specifications. measurements 33–46%, 36–51%, 20–22%, 6–8% respectively, higher than those obtained PACs. Based on test results, PRPs showed good physical performance considered method controlling transport pollutants.
