Review
This guide prepared by Mr. Post Bahadur Dangol for Bituminous Surface Dressing work reflects the true picture of his practical experience in the construction of Hetauda Narayanghat Highway Project especially for Double Bituminous Surface Treatment work (DBST).
Mr. Dangol has gained practical experience and knowledge in the field of bituminous works since 1961 during the construction of Tribhuvan International Airport Kathmandu Valley Road Nepal
In this guide, he has truly represented all the activities in sequence from the beginning of double bituminous surface treatment works to the final setting. He has explained how much quantity of bitumen at what temperature has to be sprayed, spray rate of aggregate in different stages and use of different equipment at those stages. During the construction activities, all the required laboratory tests of materials, checking and trial tests of equipment, handling of manpower use of relevant standard charts and tables are elaborated as per actual field conditions.
Although this guide is concentrated on Hetauda Narayanghat Highway Project, it is indeed a very useful reference to all concerned client, consultant and contractors related to bituminous work.
Finally I would like to congratulate Mr. Dangol for his effort to prepare this guide. I consider this guide is an asset in the field of bituminous work.
