Project introduction

The issue of dust carried on unpaved haul roads and emission of dust particles under PM-10 received significant consideration in recent years due to its huge effect on global air quality.

Especially in areas considered as major dust emitters such as quarries, mines, dirt roads, construction sites, landfills, and waste processing sites, in which vehicular traffic causes dramatic changes in ground stability, resulting in Aeolian (wind-borne) drifting and emissions of huge dust amounts into the atmosphere.

Awareness of the direct and indirect damages of dust emission to global ecosystems and humans is increasing. Current global estimates of soil erosion and natural lifting of dust into the atmosphere are still very rough, yet range from 500 to 3000 million tons per year while human activity exacerbating air pollution by 20%-50% and exceeding the threshold approved by environmental law enforcement authorities in numerous places in Israel and worldwide.
Especially in populated areas located near mines and quarries.

Unpaved haul roads used by heavy vehicles are a significant source of smaller than PM-10 airborne dust particles. These vehicles erode and crush the topsoil, destroy the substrate and thus encourage emission of wind-born particles carried to great distances. Historically, different materials are using to suppress dust, but global standards changed recently.

Prohibitions and restrictions is applied to the use of many dust suppressants, with a significant impact on dirt road users, which resulted in the high number of accidents and the decreased general safety of the road are caused by poor visibility created by heavy air pollution.

These also resulted in increased damages to work tools of the entire site up to the extent of shutting down the worksite, resulting in low productivity, money losses, higher incidence of respiratory diseases in humans and animals, damage to agricultural areas and natural vegetation as well as water sources contamination.
