The tests with SSA as 30% of the fine aggregate |in concrete revealed that these specimens satisfied the more lenient hazardous waste classification limits, though the detection limits were not sufficiently sensitive to allow further comparison to the more stringent soil or water quality thresholds. Though the allowable leached concentrations should be much higher than these Japanese thresholds, the Cr(VI) results perhaps suggests that the use of SSA in this form may need some conditions. In this form, the leached elements concentrations satisfied the most stringent Japanese water quality limits, with the exception of Cr(VI) ( Sato et al., 2012, 2013).

SSA was classified as a material that has some potential for use as fill, capping or subbase, though restrictions may be needed in its use to avoid overly unfavourable conditions.Īs described in Section 8.3, SSA has been mixed with fresh concrete, which was subsequently hardened and crushed to be used as a base course material. Its potential use in unbound form as fill, capping and subbase ( CIRIA, 1997) and hydraulically bound as base course material ( Khanbilvardi and Afshari-Tork, 2002 Sato et al., 2012, 2013) has also been dealt with, albeit to a slightly lesser extent.Ī CIRIA (1997) report put forward a leaching classification system for assessing the potential use of waste material in road construction, based on the released element concentrations compared to the drinking water limits. It was found that more of the leaching testing work has been done on the most natural suitable option of using the material as a filler in bituminous bound mixtures ( Enviroscience, 1982 Japan Sewage Works Agency, 2010 Khanbilvardi and Afshari-Tork, 2002 Purdue University, 1991 Sato et al., 2012, 2013).

As such, the leaching performance of SSA used in bituminous bound, hydraulically bound and particularly unbound form carries significant importance.Īs has been the case throughout this work, the environmental impact of SSA as a road pavement material is dealt with in full in Chapter 9, though a shorter version of the assessment is provided in this chapter for completeness. Similar to the use of SSA in geotechnics, its inclusion in road pavements is one of the more environmentally sensitive applications, with the potential for harmful elements released from the ash to make their way along a direct path into the water system.

KDOT asks motorists to reduce their speed, watch for construction workers and vehicles entering and leaving the site and obey flaggers and traffic control devices. Motorists should expect delays while traveling through the work areas, consider alternate routes and expect additional commute time. Roads will remain open during treatment, but will be reduced to one lane of travel using flaggers and temporary daily lane closures. Roads listed on the projects map below include Randall Road, Plank Road, Big Timber Road, Huntley Road and Bowes Road. Monday through Friday for about two to three weeks. Construction work hours will be from 7 a.m. Work is expected to occur from the south end of the county progressing north until all roads listed have been completed. The process will involve applying a rejuvenator liquid, allowing the liquid to cure, placing sand on the treated roads for traction, and then sweeping up the excess material. By conducting these improvements earlier in the life cycle of the asphalt pavement, KDOT can reduce the water penetration that leads to freeze/thaw damage and prevent oxidation of the asphalt material. Schumacher said pavement preservation techniques such as this are lower-cost maintenance improvements. “As these roads have been resurfaced within the last two years, it is important to protect the new asphalt with the pavement rejuvenator,” Kane County Division of Transportation Project Manager Matt Schumacher said in a news release. Starting the week of May 3, Kane County will begin the process of applying an asphalt sealer/rejuvenator on the below listed roads as part of the county’s annual maintenance program.
