Improvement of Forest Road Gravel Surfacing Quality by Nano-polymer CBR PLUS
نویسندگان
چکیده
In this study, CBR PLUS was used on gravel roads to reduce erosion and consequently maintenance costs of forest road network. Nano-polymer CBR PLUS with weight percentages of 0.25, 0.50, 0.75 and 1.00% in water were added to the surfacing materials of a forest road in Nekachoob Company of Iran. A comparative soil chemical and mechanical test for untreated and treated soil was carried out to observe variations in results. The results showed that by increasing the percentage of CBR PLUS, the soil fine particles content decreased. In addition, with increasing the CBR PLUS content, a decrease of the liquid limits was observed in soil. Soil treated with CBR PLUS, resulted in improvement of soil dry density and California bearing capacity (CBR). Moreover, the amount of Calcium, Magnesium, Potassium ions increased with the increasing CBR PLUS. Finally, it was concluded that 1.00% of nano-polymer CBR PLUS acted better in comparison with lower concentration. However, it is suggested that higher levels of this substance should be evaluated in future studies.

Where pavements pass through highly developed areas, I think such service drives will be necessary to overcome constant interference of traffic turning in and out of the property with through traffic. These service drives would not, of course, be improved to nearly as high type as the through pavements. In most cases a surfacing of...
