Adding Recycled Asphalt Pavements in Gravel Roads to Control Traffic Generated Dust available in PDF, EPUB and Kindle. Research Paper (undergraduate) from the year 2017 in the subject Engineering - Civil Engineering, Addis Ababa University, course: Road and Transport Planning, language: English, abstract: As many of the developing countries Ethiopian's road network is mostly gravel. It comprises 82.7% of the road network. Road users and residences around these roads highly exposed to the dust generated due to traffic. In the past years so many techniques of dust reduction has been applied, starting from application of water to using chemical adhesives. In this work an alternative option for dust reduction is presented. Sub base materials from Gelan-Insilale-Legedadi DS6 road section and tear off asphalt pavement from Kality-Akaki road were bagged, tagged & transferred to laboratory. In laboratory in order to determine the engineering property ASTM & AASHTO standards were used. Precipitation Data from Ethiopian National Meteorology Agency, traffic count, vehicle classification of federal highway administration and laboratory test results of silt content & particle size multiplier K-value were used for adopting EPA3 dust quantification model & fugitive dust handbook equation. MINI-TAB17& Excel analyses were used to analyze the data. The result shows blending the 70% sub base with 30% RAP the dust emission was reduced by 17%. The method was also found to be both ecological & economical.

As more Recycled Asphalt Pavement (RAP) becomes available to use in roadways, The Wyoming T2/LTAP Center and two Wyoming Counties investigated the use of RAP in gravel roads. The Wyoming DOT and the Mountain-Plains Consortium funded this study. The investigation explored the use RAP as a means of dust suppression on gravel roads while considering road serviceability. Several test sections were constructed in two Wyoming Counties and were monitored for dust loss using the Colorado State University Dustometer. Surface distress evaluations of the test sections were performed following a technique developed by the U.S. Army Corps of Engineers in Special Report 92-26: Unsurfaced Road Maintenance Management. The data collected were summarized and statistically analyzed. The performance of RAP sections was compared with the performance of gravel control sections. This comparison allowed for fundamental conclusions and recommendations to be made for RAP and its ability for dust abatement. It was found that RAP-incorporated gravel roads can reduce dust loss without adversely affecting the road's serviceability. Other counties and agencies can expand on this research to add another tool to their toolbox for dust control on gravel roads.

This book was released on 2000. Gravel Roads available in PDF, EPUB and Kindle. The purpose of this manual is to provide clear and helpful information for maintaining gravel roads. Very little technical help is available to small agencies that are responsible for managing these roads. Gravel road maintenance has traditionally been "more of an art than a science" and very few formal standards exist. This manual contains guidelines to help answer the questions that arise concerning gravel road maintenance such as: What is enough surface crown? What is too much? What causes corrugation? The information is as nontechnical as possible without sacrificing clear guidelines and instructions on how to do the job right.

As the volume of traffic on unpaved roads in Wyoming increases with increased drilling activities, dust loss and surface distresses will continue to rise. It would make sense to pave some of these roads, but many counties cannot afford these expensive operations especially when future traffic volumes on these roads are unknown. An alternative option needs to be explored that will reduce dust loss and associated surface distresses.
