An immense problem affecting environmental pollution is the increase of waste tyre vehicles. In an attempt to decrease the magnitude of this issue, crumb rubber modifier CRM obtained from waste tyre rubber has gained interest in asphalt reinforcement. The use of crumb rubber in the reinforcement of asphalt is considered as a smart solution for sustainable development by reusing waste materials, and it is believed that crumb rubber modifier CRM could be an alternative polymer material in improving hot mix asphalt performance properties. In this paper, a critical review on the use of crumb rubber in reinforcement of asphalt pavement will be presented and discussed. It will also include a review on the effects of CRM on the stiffness, rutting, and fatigue resistance of road pavement construction.

Hosken Reserve: grass oval used for soccer training, informal reacreation, off-lead dog exercise Photo by John Englart. The conversion of a grass oval to synthetic turf at Hosken Reserve, Coburg North, is about a failure in transparency and consultation with the local community, and poorly framed triple bottom line decision making by Moreland Council. There are questions about the integrity of the triple bottom line decision making embracing the social, environmental and economic impacts, costs and benefits, that was used in the process in the past decade for this site. And there are questions how triple bottom line decision making and weighting of factors will be applied for the current process. This literature review provides numerous reasons why conversion of a natural grass oval and open space to a fenced synthetic soccer pitch should not take place. It finds that there are two primary reasons against synthetic turf at Hosken Reserve, and that either reason is significant in itself for the primary project not to go ahead.
Abstract Background: All around the world tire disposal is becoming a greater environmental problem. The installment of recycled tire crumb rubber fields and playgrounds are one way communities have decided to relieve the issue of end-of-life tire disposal. Many laboratory toxicology studies have identified hazardous chemicals within these shredded tires to include polycyclic aromatic hydrocarbons PAH , volatile organic compounds VOC , semi-volatile organic compounds SVOC , and as well as heavy metals such as lead and fine particulate matter. Objective: This paper aims to systematically review the current literature on the association between exposure to tire crumb rubber playgrounds or fields and the air pollution health risk to children worldwide.
What research is included in the Federal Research Action Plan? Will it answer the question of whether tire crumb is safe? The research activities have been prioritized based on data needs and available resources. This study will provide a better understanding of the chemicals found in tire crumb and the potential exposures that field users may experience by using these fields. This study, in and of itself, will not determine if fields are safe, but this work is a necessary first step that needs to be taken.
